Most of us don't think about our car’s radiator plastic tank until we have to. One day, everything’s running fine, and the next thing you know, you see steam rising from under the hood or a suspicious puddle forming beneath your car. It’s at this moment you realize how crucial that plastic tank is. So, now you need a replacement. But how do you choose the right one when there are so many options out there? Whether you're a DIY enthusiast or someone just trying to avoid another costly repair, here’s everything you need to know about picking the correct radiator plastic tank for cars, the kind that won’t let you down a few months later. Understand Your Car First This might sound obvious, but you'd be surprised how many people order the wrong part. Start with the basics: your car’s make, model, year, and engine size. Even a small difference, like the engine type or a mid-year model change, can mean a completely different radiator setup. Check your owner's manual or pop the hood and take a picture of your current radiator tank. If you're unsure, you can also call an auto parts store with your VIN number. It’s a simple step that saves a ton of frustration later. OEM vs. Aftermarket: Know the Difference Next up, you’ll notice most parts are either OEM (Original Equipment Manufacturer) or aftermarket. So which should you choose? OEM parts are made by the manufacturer (or their certified partners), meaning they’re the exact same part your car came with. They fit perfectly and usually offer peace of mind, but that often comes at a premium price. Aftermarket parts can be a great value, but they’re a bit of a mixed bag. Some are made by top-tier brands and work just as well as OEM. Others might save you money upfront but crack or leak within months. When going aftermarket, research the brand, read reviews, and avoid suspiciously cheap options. Not All Plastic Is Created Equal Even though it’s called a “plastic tank,” it’s not just any plastic. Your radiator tank has to handle extremely high temperatures, pressure, and vibrations every time you drive. Look for tanks made from reinforced nylon, glass-filled polymers, or UV-resistant plastics. These materials are specifically designed to handle under-the-hood heat cycles and won’t degrade or become brittle as quickly. If the product listing doesn’t specify the type of plastic used, take that as a red flag. Inspect the Craftsmanship (Even If It's Online) Take a close look. Smooth seams, even wall thickness, and no visible air bubbles or mold defects are signs of quality manufacturing. These little details matter because they determine whether the tank will seal properly and survive repeated heating and cooling cycles. If you’re shopping online, check for close-up photos, or even better, look for video reviews. You can often tell a lot about the product just from what other users share. Don’t Overlook the Extras Some radiator plastic tanks come as part of a complete kit, including things like: Mounting hardware Radiator caps O-rings and seals Overflow hose connections Others come as just the bare tank. Kits may cost a bit more, but they often make installation easier and prevent return trips to the auto parts store. If you’re not particularly handy, having everything in one box can be a real time-saver. Can It Handle the Heat?  It’s easy to forget just how hot things get under the hood. Your radiator tank deals with temperatures that can exceed 200°F (93°C) during normal operation. That’s a lot to ask from plastic. Always check if the tank is rated for high-heat applications. Some listings will specify temperature resistance or operating pressure, others won’t, and that’s not a good sign. You don’t want to risk a blowout on a hot day just because you saved a few dollars. Was It Pressure Tested? The cooling system in your car is pressurized, so any weak point, like a poorly made radiator tank, can lead to leaks or even total failure. A quality tank will have undergone pressure testing to ensure it can hold up under real-world driving conditions. Look for terms like pressure-tested, DOT-certified, or ISO compliant. These aren’t just buzzwords; they’re your assurance that the tank won’t fail the first time you get stuck in traffic on a summer day. Check the Fitment (Twice!) Fit is everything. Even if a tank is technically “compatible” with your car, that doesn’t always mean it will line up perfectly with the radiator core, mounting brackets, or hose connections. Misalignment can lead to coolant leaks, rattling, or worse, total system failure. Dig into reviews from people who own the exact vehicle. Did they need to trim the hoses? Drill holes? If the fit isn't perfect out of the box, it's probably not worth your time. A Good Warranty Goes a Long Way A solid warranty shows the manufacturer stands behind their product. Look for a warranty of at least 12 months, and avoid sellers that don’t clearly state their return policy. Bonus points if the brand offers good customer support. Being able to call or email someone when you're stuck mid-installation is more helpful than you might think. Real People, Real Reviews Don't underestimate the power of user reviews. If you’re buying online, read what others have experienced with the product. Look for answers to questions like: How easy was it to install? Did it fit perfectly? Did it crack or leak after a few months? Filter out generic or suspicious reviews. Focus on the ones that include specific details or photos from people who installed it themselves. Don’t Let Price Be the Only Deciding Factor We get it; car repairs can get expensive fast. It’s tempting to grab the cheapest tank and hope for the best. But remember: you’re protecting your engine, one of the most expensive parts of your car. Cheaper tanks often cut corners on material or testing. A slightly more expensive part could last for years, while the bargain version might cost you a full radiator replacement down the line. Availability of Matching Accessories If the tank has a unique cap, mounting style, or hose setup, check whether replacement parts or accessories are available. It might not matter today, but in six months, if the cap cracks or a hose connector wears out, you’ll appreciate having access to matching components. Wrapping It Up: Choose Smart, Drive Safe Choosing the right replacement for auto radiator plastic tank isn’t something you want to rush. It might seem like a small part, but it plays an important role in keeping your engine cool, your coolant contained, and your car running reliably. So take a few minutes to compare materials, check compatibility, read reviews, and choose a tank that’s built to last. 

The process of locating the correct plastic tanks to use in an auto radiator seems like looking for a needle in a haystack. There are a lot of suppliers available in the market, so how do you get to know which suppliers will provide quality parts that you can count on? This blog will take you through everything you need to know about acquiring high-quality radiator plastic tanks for your business. The Knowledge of What Makes Radiator Tank Quality First, we will make a point about what distinguishes good radiator tanks from bad ones, and then we can move on to sourcing. A good radiator plastic tank must not burst or warp under severe temperature conditions. It must be corrosion-resistant to coolant chemicals and sealed tightly against pressure. The highest-quality tanks are made from high-quality plastics, such as PA66 (nylon) or reinforced polypropylene. These items can withstand the heat cycles to which they are exposed by car engines every day. The low-quality, inexpensive tank plastics usually wear out, making them brittle and, hence, expensive to break down. Search for tanks that have even, smooth surfaces and no defects, such as bubbles or jagged edges. Mounting points must be strong and well-reinforced. Keep in mind that at any given time, a radiator tank failure could find a customer on the roadside, and the quality of a tank should never be compromised. Research your Potential Suppliers The first step in your search should be to create a list of possible suppliers. Never select the first company you see on the web. Research on the options will be conducted at a later time. Check the years of experience and the other businesses they are engaged in. A good supplier must possess a good history of manufacturing automotive parts. Seek suppliers of aradiator parts as opposed to suppliers who manufacture all types of plastics. Read customer reviews and testimonials, but be cautious when trusting them completely. Some individuals may be dishonest, while others may reflect unrealistic expectations. Essential Questions for the Suppliers • Be prepared to ask the right questions when calling potential suppliers. Inquire about their control process and their certifications. • Ask them about the materials and the reasons why they have used the particular plastics. An ideal supplier should be able to provide the technical advantages of their material selection. Enquire about their test procedures as well. Do they pressure test every tank? What is their test of temperature resistance? • Do not forget to ask them about their production capacity and lead times. You do not need to collaborate with a supplier that you cannot satisfy or one that will take several months before shipping products. Request some references from other customers, particularly those in the same business as yours. Testing of Quality of Materials When it comes to plastic, not all plastics are good, particularly those used in radiator tanks. This material must be able to withstand coolant temperatures of up to 200°F and remain flexible at freezing temperatures. Glass-reinforced PA66 (Polyamide 66) hardware can be considered the gold standard for radiator tanks. This material exhibits excellent heat-resistant qualities, chemical compatibility, and durability. Other suppliers may propose lower-cost substitutes, such as regular polypropylene, which, however, does not work well under extreme conditions. Suppliers should be asked to provide material certificates and test reports. This should include temperature resistance, chemical compatibility, and pressure testing of these documents. If a supplier is unable to provide such information, it should be considered a red flag. Importance of Manufacturing Process Tank production encompasses both the quality aspect and the materials. The most widespread ones are injection molding, but the specifics are important. Enquire on the quality of the molds, injection pressure, and cooling. High-quality manufacturers maintain precise temperatures during molding to prevent internal forces that could cause future cracking. They also use proper cooling cycles to ensure the plastic sets correctly in the tank wall. Quality control and testing A supplier of high-quality goods must have robust testing mechanisms. It is necessary to put a tank under pressure. Pressure testing is essential; tanks must be tested under pressure far greater than usual to ensure they will not fail under stressful situations. Temperature cycling tests are used to determine the potential harm caused by the expansion and contraction of materials. Request them to show you their quality control paperwork. Good suppliers maintain good records of every batch of production, certifications of materials, and test results. They should be able to trace any tank in terms of its date of production and material lot. Other suppliers make other tests, such as vibration resistance tests or accelerated aging tests. Such tests are not always required, but they can give additional assurance in high-performance applications. Managing Good Supplier Relations When you get a sufficient supplier, you should develop a strong relationship with them. Communicating regularly will help avoid misunderstandings and also alert you to any variations in their processes or materials. Try visiting their facility if you are able. Visiting their operation will enable you to get firsthand information concerning their capabilities and quality levels. It also demonstrates to the supplier that you are in business. Nevertheless, do not place all of your eggs in one basket. Backup suppliers will help you to continue production despite the difficulties with your primary supplier. Involve secondary suppliers by placing product orders periodically, as needed, to maintain demand. Expenses and Values • Price matters, but it is not the only thing that you should consider. The low-cost tanks will also be the most expensive in the long term because they will attract warranty claims and customer dissatisfaction. • Consider total ownership costs, not just unit price. A more expensive tank provides better value with twice the longevity. To choose the best alternative, compare suppliers based on delivery, minimum order criteria, and payment terms. • When you have a regular demand, you can ask to negotiate volume discounts. Best deals are provided by numerous suppliers when the sizes of orders are larger than usual. However, ensure that you can utilize the volumes you are committing to effectively, as excess inventories block both cash and space. Best Practices of Sourcing Obtaining high-quality plastic radiator tanks is quite tiresome and time-consuming. Do not hurry and shorten the research. The money you will spend initially on identifying a suitable supplier will be rewarded by customer satisfaction and warranty costs. Remember, the lowest price isn't always the best. Pay attention to suppliers that can appreciate your demands regarding quality and are consistent. Maintaining relationships with multiple suppliers ensures the supply chain remains resilient. And last but not least, do not sacrifice quality and spend a few extra dollars. Failure of the radiator tank may lead to engine damage and leave the customer stranded. Your reputation is based on the quality of the parts you purchase, so select suppliers who share your commitment to quality and excellence.

People know how crucial it is to replace a damaged plastic radiator tank. When problems like cracks, holes, and tears start, the countdown for the replacement process begins. An engine needs full support from the radiator tank, especially for long journeys and hot regions. Any leaking tank could lead to a disaster for the engine, and this is where users have to find a replacement faster. If you are one of them, you might also have questions regarding replacing the plastic radiator tank. Before you go for the solution, here is what you should know.  Metal Tanks Can Resist Heat Much Better There is no doubt that metal tanks are better than plastic ones in terms of strength. What makes them superior is their heat resistance. No matter how strong a plastic tank is, it can not last against extremely hot conditions. However, metal tanks can deal with these situations quite easily and for longer. Therefore, replacing plastic radiator tanks in your car with metal ones will give you higher heat resistance. You will not have to worry about deformity in extreme conditions. Metal can withstand these conditions much longer than you can imagine.   Replacing a Plastic Tank with a Long-Lasting Metal Tank That long-lasting performance comes because the metal type will not melt or crack. Unlike plastic, it will not give up in extreme conditions. Therefore, replacing plastic tanks could benefit people driving in hot regions. They will not have to worry about heat-related damage inside the tanks. As a result, the vehicle will not demand a new tank after a few years in an extremely hot region. However, a plastic tank can survive long enough to cover your cost, but not as long as a metal tank. Metal tanks are specially built and are strong enough to deal with harsh conditions. No Impact will Cause Cracks in the Tank Impacts are common when you talk about machines. Since automobiles have various components inside them, the risk of impacts increases. This is another advantage when replacing plastic tanks with metal tanks. They have better shock resistance than plastic, which makes them impact-resistant. Moreover, the dents and cracks do not occur in the metal tanks unless a much more powerful hit is taken from a sharp object.  Harsh Chemicals will Be Harmless for Metal Tank Likewise, some coolants may have harsh chemicals. These chemicals can cause plastic to leach or face internal damage faster than metal. That makes the metal tank better than the plastic type. If you replace a plastic tank with a metal tank, you will probably get better resistance against harsh coolants. Such coolants have almost no impact on the metal surface. As a result, drivers do not have to bother to replace tanks any sooner. Metal Tanks Can’t Beat Plastic Tanks in Some Factors   You must accept that plastic tanks are still beneficial, even with their disadvantages. The benefits they offer are still irreplaceable by metal tanks. What makes plastic tanks better than metal tanks is mentioned below.  • Plastic Tanks are Corrosion-Free Plastic tanks have a huge advantage that can never be ignored. That advantage is their corrosion-free surface. Plastic can not be corroded since it is not metal, so plastic tanks are better than metal tanks. If metal tanks get corroded, they start losing their surface strength. Then, the risk of leakage and shortage of coolant starts occurring. This is not the case with plastic tanks. Water and coolant can not cause any damage to the plastic ones at all. • They are lightweight  The weight of components matters a lot in a machine's overall performance. Engineers choose lightweight components to keep the fuel average good because speed is affected by it. This is where plastic tanks become a better choice than metal tanks. Their lightweight bodies make them compatible with modern cars. There is no worry regarding excessive weight because these tanks are already lightweight.  • Much Cheaper than Metal Tanks Another reason many companies prefer to install plastic tanks is the cost of production. Therefore, users also choose plastic tanks when they choose to buy new ones. Their production cost is low, and so is the replacement cost. Many drivers prefer to go for an affordable option when it comes to car parts. They have to maintain their monthly budgets. This factor contributes to the selection of plastic tanks for radiators. • Available in Flexible Designs Likewise, plastic tanks are available in flexible designs. Their production method is different from that of the metal type. That method is injection molding, which has much more flexibility than metal. That is why modern cars need different designs that are easily compatible with plastic radiator tanks. Manufacturers can make any shape or design using the same machine.  Conclusion A car radiator can have many troubles after it crosses its durability limit. Therefore, people have to replace it before things get worse. The question arises whether they should replace it with the same plastic tank or with a metal tank. Both have various advantages and disadvantages. After reading the above reasons, you can decide when you need a plastic tank and when you need a metal tank. It all depends on your condition.  

Radiator tanks are fundamental components that keep an automobile moving. Minor damage to this component can stop your vehicle, which shows how essential an ordinary-looking radiator tank is. Some users often assume the choice regarding plastic radiator tanks could be bad. The reason is the heat, pressure, and vibrations near the engine, which can cause consistent threats to the plastic tank. However, it can survive longer than an expert can imagine. It does so through its different types that fit various applications. Types of Plastic Radiator Tanks You can find not only one but four types of plastic radiator tanks in the automotive industry. Each type has a specific advantage over the others. Some have more customizability and lightweight bodies, and some have better durability and higher resistance to wear and tear. Each type meets the specific requirements of automobile users.  • Polyamide radiator tanks • Polypropylene radiator tanks • Fiberglass radiator tanks   • Polyethylene terephthalate radiator tanks   Benefits of Choosing Plastic Radiator Tank Many reasons behind the success of auto radiator plastic tanks that make global users prefer it in certain conditions. These conditions are related to budget limits, flexibility of production, car type, and living conditions. All the reasons below will make things clear for you. 1. Lightweight The first reason your car needs a plastic radiator tank is its lightweight body. This weight factor has a great impact on a car's overall efficiency. The fuel average is affected by the load inside a car. The heavier it gets, the slower it will drive. Therefore, plastic provides a lighter structure than metal. 2. Easy to Repair and Replace You don’t need a mechanic to weld the radiator tank. Unless it is made of metal, you can repair it yourself. You only need epoxy to fill every hole and crack in a plastic radiator tank. Tiny damages can not bother you for long when you have epoxy to repair. Even if it has significant damage, you can replace it with a new, affordable one. 3. Less Expensive Than a Metal Tank Since plastic is cheap, it is less expensive than a metal tank. As a result, replacing the radiator tank is very affordable. However, going for a metallic tank will be more costly than almost all types of plastic tanks.  4. There is No Risk of Corrosion  Since water and coolant are filled inside the radiator tank, you can expect the risk of corrosion. However, if the radiator tank is plastic, there will be no such risk. There will also be no risk of corrosion-based cracks and holes. 5. Customizable in Any Shape  Another major advantage of plastic radiator tanks is customization. Plastic’s high moldability makes it easily customizable. There will hardly be any kind of automobile whose design can not be compatible with plastic radiator tanks. All it takes is a custom mold, and the results will be available in the form of a custom plastic radiator tank. 6. Limitations of Plastic Radiator Tanks Everything has some limitations, and so do plastic radiator tanks. These limitations make them an insufficient choice for some automobiles and environmental conditions.  7. Less Durable Plastic does not last long in extreme conditions. Since automobiles have engines inside, the heat of the engine and other parts can damage plastic radiator tanks. This extreme condition makes plastic radiator tanks a weak component in some conditions. Therefore, they are a less durable choice than metallic options. 8. Prone to Early Cracks and Holes Many components cause vibrations, which cause problems for surrounding parts unless they are made of durable material. Plastic radiator tanks can not bear extreme conditions of shocks and vibrations for a long time. Because of their short durability, they start having cracks and holes. This is the problem with rubber and plastic components, which is why they are replaced faster than metal components. 9. Can’t Survive Long in Extreme Heat  Extreme heat can deform plastic; the same can happen to plastic radiator tanks. However, they are made of heavy-duty plastic like PET, PP, fiberglass, and PA. Even some conditions, like scorching weather and an engine’s overheating, can cause damage. These conditions make it hard for plastic radiator tanks to survive long, unlike metal types.  10. Harsh Coolant Can Cause Wear and Tear Some harsh coolants can damage plastic radiator tanks and cause wear and tear inside them if the concentration is high. Some plastic types have low resistance to highly concentrated coolants. That’s why it could be a problem for automobiles if the plastic tanks are not compatible with the coolant type. 11. Environmental Pollution Lastly, plastic does not decompose, and it takes over 100 years for that to happen. That makes these tanks a problem for the environment. This concern will always be a main highlight unless many discarded plastic tanks are recycled. Materials Used in Radiator Top and Bottom Tanks: Specification  Most modern radiators' top and bottom tanks (in cars) are made of plastic. However, these aren’t all plastics; they are specialized engineering plastics built to resist heat, pressure, and chemicals. Materials Engineers Used: Glass-reinforced nylon (PA66-GF30) (Also referred to as Nylon 66, this product includes 30% glass fiber in its polyamide 66 base) Can It Handle 200°F? Yes, absolutely.200°F (≈93°C) is well within the safe operating range for PA66-GF30. In fact, Most radiators operate between 190°F to 220°F. This material is designed for exactly that environment  Used In: Passenger cars Light trucks Some heavy-duty applications (depending on design)   Other Variants Sometimes Used PA6-GF30 (similar to PA66, but slightly lower heat resistance) PPA-GF (Polyphthalamide, used in higher-performance applications) PBT-GF (Polybutylene Terephthalate + Glass Fiber, sometimes in European cars) Conclusion  The automobile industry focuses on lightweight components that offer durability and strength. This helps them produce vehicles that give better averages than previous models. Every new model is better than the previous one regarding the components' material quality and weight. Radiator tanks are among those components that are crucial for every automobile. When it comes to plastic, it fulfills most requirements but also leaves some limitations.

Cars have to be lightweight and efficient for long-term performance. Their speed and power generation require complete support from their engines. Since engines require protection from overheating for continuous movement, radiators do their job to keep the vehicle’s temperature within limits. A radiator is like a safety device that saves drivers from getting stranded with an overheated engine in the middle of their trip. This is how essential radiators are. Since plastic and metal have a certain level of competition in auto parts, people often consider using plastic radiators due to their lower cost. The question that comes to their minds is about the low heat resistance and fragility of the plastic surface against massive shocks.  What Are Plastic Radiator Tanks? Aluminum cores and plastic tanks are typically used to make auto radiator plastic tanks. For better thermal conductivity, metal is still used for the core where heat exchange takes place. But the coolant tanks are made from high strength plastic materials such as nylon reinforced plastic. This hybrid construction achieves a balance between performance, cost and weight which is why plastic radiators have become the preference of many car manufacturers over full metal ones. Benefits Of Auto Radiator Plastic Tanks If you look closely, there are different types of radiators that are available in the industry. Some are known for their heavy-duty performance against heat, UV rays, and pressure. It shows that plastic radiators are made from a tough and durable type of plastic. If you still have doubts, here are the pros of choosing plastic radiators for your car.  Lightweight Body The first feature that makes plastic radiators better for some drivers is their lightweight bodies. Since the weight factor significantly contributes to a car's performance, plastic radiators are beneficial in this regard. These lightweight radiators hold the water firmly without adding extra weight. The car’s mileage average remains stable because of this benefit. You might think that plastic can’t survive long enough due to its lightweight structure, but it can last for several years. It will help users recover the price in a reasonable amount of time. Low Cost of Production  Plastic is cheaper than metal, which makes plastic tanks more affordable. Comparing them to metal radiators shows a significant difference in their prices. Plastic radiators are cheaper due to their low production cost. Hence, they are more affordable and also available everywhere. However, durability is lower than that of metal, but their low cost makes them less expensive in the replacement process. Since plastic has a weakness, which is heat, you can imagine the aftermath. However, hard plastic is used that has long-lasting resistance against mild heat. People who live in cold regions might like plastic radiators because the heat factor will not bother them. Their Repair Kit is Easily Available The repair kit requires a few plastic patches and an epoxy tube. This readily available kit helps users deal with minor holes in the plastic radiator. They don’t have to buy new radiators because of this affordable solution. Repairing radiator tanks is easy because anyone can do it. As compared to metal, you don’t need to weld it. You only need epoxy tubes for radiators to mix and make a solution. Then, apply that solution to the crack or hole in the plastic radiator. Dry that area by leaving it for some hours. Once it dries up, you can drive your car again as usual.  Maintenance is Often User-Friendly  The same is with maintenance, where you don’t have to do much. Plastic radiators require minimal maintenance. All you have to do is inspect any signs of wear and tear on them. If there are some, you can use epoxy to repair them. If the situation is dire, replace your radiator with a new one. It will be an affordable and swift repair as compared to other types of radiator maintenance.  No Need to Worry About Corrosion The biggest advantage plastic radiators have is their anti-corrosion body. Plastic is a natural anti-corrosion material, which is why water and coolant do not cause any problems with it. You will find no rust or corrosion inside the radiator tank. Thus, the coolant remains clean, and the water inside the radiator also remains clear. You will not find a rusty color when you add more water to the radiator. However, some metal parts are still used in plastic radiators, which can cause rusting. The good thing is that you can prevent massive corrosion by choosing a plastic radiator. Low-Cost Replacement The replacement process is as budget-friendly as maintenance. Plastic radiators are cheaper options, which makes their replacement process affordable for most drivers. If you explore the market, you can find many low-cost radiators of good quality. It means you can replace your old radiator at a very low price. Sometimes, it is better to replace the entire radiator than to repair it. It is because of the price difference between plastic and metal radiators. Low-cost replacement is a significant factor that keeps plastic radiators at the top of the priority list for many drivers. Conclusion Besides all these benefits of installing plastic radiators, you will find some challenges with them. These challenges are related to the low resistance of plastic radiators against heat and shocks. Therefore, plastic radiators have much less durability than metal ones. Overall, plastic is a good choice in modern cars that have lightweight features. 

Radiators are among the most essential components of an automobile. If there were no radiators, drivers wouldn't have been able to drive their vehicles for more than a few minutes. It includes the tanks that help them regulate the temperature to keep the car less heated for long journeys. Find out all about them below. About Radiator Plastic Tanks  Automobile radiator tanks carry water and coolant to regulate the engine's temperature. Both metal and plastic types are available in the market, but plastic tanks are also used. They are lightweight radiator tanks that prevent heat dissipation from the radiator. Since modern vehicles are more focused on lightweight bodies and agile performance, plastic tanks are preferred. They do everything a modern automobile needs from them.  Types of Radiator Plastic Tanks in the Industry These auto plastic radiator tanks are not always plastic because the heat and pressure can cause damage. To prevent that risk, the auto industry uses plastic, nylon, and fiberglass, depending on a car's condition. Therefore, you can find some types available in the auto industry regarding material type. Nylon/Polyamide (PA) Plastic Tanks  PA66 is one of the most used radiator tank materials in the auto industry. The reason is its chemical and heat resistance. Since an engine releases heat around it, all the components have to be heat-resistant. Moreover, coolant is a chemical that can corrode regular plastic. Therefore, PA radiator tanks are chemical and heat resistant. They are made of glass-reinforced nylon, which has a lightweight structure and durability for auto applications. These radiator tanks can last longer than usual plastic types.  However, there are some cons to using PA66 radiator tanks. Since nylon absorbs moisture, it can be deformed or mechanically damaged in harsh conditions. Moreover, it is a brittle material, which can lead to cracking or damage from sudden shocks. PA radiator tanks are more expensive than other plastic tanks.  Polypropylene (PP) Plastic Tanks  Another common type is the PP radiator tank. It is a cost-effective type with enough strength and weight for an automobile. The heat resistance revolves around 90 degrees Celsius, which makes it another good option for radiator tanks. Also, its flexibility makes it an ideal option for many types of automobiles. Besides, it can resist chemicals like radiator coolant for top performance. Its lightweight structure poses no extra weight in the automobile.  Fiberglass/Glass-Reinforced Plastic (GRP) Tanks  Here is a combination of fiberglass and plastic, which makes these radiator tanks an acceptable option for automobiles. There is a high strength-to-weight ratio in GRP radiator tanks. They last longer than plastic types, making them suitable for modern cars. Even their heat and chemical resistance is higher than usual plastic types.   A disadvantage of using them is their brittleness. They can crack under high stress. Polyethylene Terephthalate Tanks  The last type, which is rare, is PET. This type of tank is not so common for radiators, but it shows good performance. It is compatible with lots of vehicles because of its chemical and heat resistance. It is also very light in weight. It is more expensive than the PP type, which is probably why it is not very common in the industry. How to Choose the Best  Radiator Plastic Tank for an Automobile?  When you are about to choose, make sure to follow some guidelines. They will let you decide better for the best performance you seek from plastic radiator tanks. Some Factors to Consider The first thing you should consider is the vehicle type you choose. The car model you drive and its age are the main factors you should consider.  Do you drive in a cold region or a hot one? The region matters a lot because the heat resistance level will be the element for which a tank is made. How much do you drive? Your driving frequency will be another consideration. If you drive a lot, it will be better to go for the fiberglass type.  Then comes your budget, deciding if you can afford the radiator tank you want.  Lastly, if you are willing to purchase plastic tanks for your retail business, you need to decide whether you want OEM quality or aftermarket.  A Few Maintenance and Care Tips for Users   Unless you do the proper maintenance, your radiator tanks will have problems in the future. You are not only supposed to replace the old one but also prevent future damage. Notice signs that can lead you to detect minor and significant damage in the radiator tank. Learn how to check for cracks and leaks, saving you from substantial loss.   Maintenance Tips  Here are some maintenance tips that you need to follow to keep things running smoothly. You may notice water stains on the ground under the vehicle, right below the radiator tank. If you notice any water stains, the radiator tank could be leaking. If you notice a low coolant level frequently, that could be a sign that you should have a look at the radiator.  If your vehicle gets overheated too early and too frequently, waiting is a problem.  Perform a pressure test on your radiator to inspect any leakage in the tank. Use the correct type of coolant that matches your vehicle model and usage level. Flush the contaminated coolant before you refill. The contaminated one will cause further problems for the radiator. Inspect the thermostat and have it repaired or replaced. Conclusion  Plastic tanks for radiators are lightweight and resistant to heat and chemicals. Their performance depends on how much you drive. Moreover, how much heat is around the radiator tank matters a lot.
