Radiator end tanks are no stranger to leaks. After some time, these tanks will wear out and become weak. Considering the tough under-hood environment, it comes as no surprise why some tanks eventually break and develop leaks. The extreme temperature and intense pressure can put them under a lot of stress. Some tanks may crack due to impact and vibration. Heat in the system can also put their strength to the test. When there are hairline cracks on tanks made of plastic, usually, super glue, epoxy, or duct tape is used as a temporary fix for the leak. For tanks made of aluminum, copper, brass, or a stronger material, soldering is done to fix the punctures. If it comes to the point where these fixes just won't work anymore, a new radiator end tank is what you need. Here's how you can get one:
Inspect the radiator and other parts of cooling system first.
By inspecting the radiator and checking other parts of the cooling system, you'll find out if the leak is only coming from the busted radiator end tank. You can also eliminate other possible problems. Before buying a new tank, run some tests, so you'll know what kind of repair, service, or maintenance is needed. Aside from the tank, you may have to buy other replacement parts.
Consider material quality.
When the radiator end tank develops a crack or gets punctured, this will result in coolant leak. This means that the cooling system won't have enough cooling fluid to go around the engine and keep the operating temperature at a safe range. This can lead to an overheating engine. To prevent engine damage caused by cooling system problems, you'll have to get an end tank that's made using high-quality materials. The tank could be made of plastic, aluminum, copper, brass, or other materials. Whatever material is used, the tank should be designed to ensure heat and hydrolysis resistance, considering the harsh conditions it's exposed to. A high-grade design can ensure extended use or long-term service. It should have a sturdy seal as well. The end tank should be manufactured to meet all material quality requirements and industry standards.
Think about the fit.
Whether it's an OE replacement or an aftermarket product, the radiator end tank should be made to fit the radiator and should be compatible with the rest of the cooling system. It should suit the vehicle's requirements, engineered to match the OE specs or at least meet the industry standards. A compatible radiator end tank will ensure proper fit and will take away some hassles in installation.
Shop around for the best features and prices.
Always check the specs. Make sure that the radiator end tank isn't only designed to fit but to also perform as it should. Some manufacturers guarantee uncompromising quality as the parts and accessories undergo strict testing and evaluation to ensure exact fit and premium function. Some aftermarket options may even offer better features. As you shop around, compare not just the price list but also the features.
