Some coolants are designed for certain types of radiators, so you need to ensure that the coolant you choose is suitable for your radiator. To make an informed decision, there are several factors you should consider before making a purchase.įirstly, you should consider the compatibility of the coolant with your specific aluminum radiator. But with so many options out there, choosing the right type can be a challenge. The cap should hold pressure up to its rating and then release, allowing pressure to escape.If you're looking for an essential component for your car's aluminum radiator, you should definitely consider getting a coolant. Pressure test the cap with an appropriate tester and adapter. Check the sealing gasket for damage that would prevent the cap from holding pressure and inspect the vacuum valve for damage that could cause it to stick, preventing coolant from flowing back into the radiator and causing collapsed hoses. Wait until the system has completely cooled and remove the cap from the radiator or expansion tank. Compare the pressure rating on the radiator pressure cap with the vehicle manufacturer’s specifications to make sure it is the correct one for the vehicle. ![]() If the recovery tank has no signs of damage, pay special attention to the condition of the radiator cap, because even a brand-new looking cap can be the root of the problem. If all of them are fine, the very next thing you should check for damage is your radiator cap and recovery tank. If you notice any signs of the coolant outside the recovery tank or on the radiator cap, or on the engine, the first thing you should do it to inspect all hoses and clamps. ![]() They can also become discolored from contaminated coolant, making it hard to judge the coolant level accurately. Although, the components are generally reliable but they can deteriorate from age and repeated heat cycling. We recommend you to inspect the coolant recovery tank for cracks and any signs of leakage on a regular basis. Since the proper function of the coolant recovery system is vital for safe and efficient operation of the entire cooling system, regular system checks are essential. Air does not present a problem for the system here because the tank is above the radiator and in this position will not aerate the coolant. The pressure cap functions the same as in the overflow system, but instead of coolant, air is released when pressure exceeds the cap’s pressure rating, and atmospheric pressure forces air back in when the coolant temperature drops and there is a vacuum in the system. In this system the expansion tank is the highest point in the cooling system, and room is built into the tank to allow for the coolant to expand and contract according to temperature. Because the tank is part of the pressurized cooling system, it is made of heavier reinforced plastic. The pressure cap is located on the tank in the expansion tank system. When the temperature of the coolant drops, a vacuum is created in the system, opening a vacuum valve in the pressure cap which allows coolant to be drawn back into the radiator. When pressure in the radiator exceeds the cap’s pressure rating, coolant is allowed to flow from the radiator to the recovery tank. In an overflow system, the pressure cap is located on the radiator and the overflow tank has a simple plastic cap. There are overflow tank systems and expansion tank systems. There are usually graduations molded into the reservoir indicating the proper coolant level, which is customarily checked when the engine is cold. ![]() In the coolant recovery system, coolant is added to a separate plastic tank that is connected to the radiator. As coolant circulates through the cooling system, it picks up metal particles, which also contributes to its classification as hazardous material. Since air causes cooling system components to rust and corrode, its presence in the system can lead to leaks of the antifreeze, which contains ethylene glycol that is harmful to the environment. One of them is the coolant recovery system, which ensures that there is no air in the system, and prevents coolant from spilling onto the ground. The engine cooling system is very complex and includes several subsystems. ![]()
