While running, your engine burns the air-fuel mixture and, as a result, produces a lot of heat. However, it works efficiently only under certain temperatures, which normally fall within the range of 185-205 degrees Fahrenheit. Excessive heat must be removed from the engine – and that’s the task of your car’s cooling system. One of its components is a radiator cap. It keeps the coolant correctly pressurized inside the system, serving as a valve that releases excessive pressure and letting coolant flow back into the radiator after it cools down. If your engine overheats, there are coolant leaks, or your radiator hose has collapsed, make sure the radiator cap works correctly.

Because a radiator cap is basically a simple part, the most common problem is a worn seal, unless the cap itself can get rusty with age or sustain physical damage in any other way. If some of the defective radiator pressure cap symptoms are indicating that the smooth operation of your motor is at risk, get a properly functioning cap in our online store. Our Chrysler 300 replacement radiator caps will restore the effective cooling system operation. Don’t compromise on its functionality as it is part of the system that protects the high-power engine of your Chrysler 300 from overheating.
