Radiator Caps

Your cooling system takes a lot of abuse, especially during the summer months. The extreme heat and pressure of your engine requires the cooling system to be at its best in order to keep your car's engine operating where it should be. Sometimes the extra pressure causes the coolant pressure to build up. The radiator cap allows this coolant to be released into a reserve tank when the pressure reaches a certain point. Without the radiator cap, the extra pressure could cause the radiator or radiator hoses to burst, potentially damaging the engine, and other components. It's important to check the cap to make sure it is working like it should every time you check your coolant.If you find the cap is leaking or has failed, it is critical to replace it immediately. There are some signs you can look out for that might indicate yours is worn out. If you see cracks in the tubes in your radiation system, this can come from air entering the system due to a defective cap. Your radiator cap can also cause leaks of coolant, resulting in low coolant levels. When the time comes, only a genuine OEM radiator cap is going to fit your radiator properly.
