Radiator caps are installed on a vehicle's radiator to keep fluid clean and help regulate engine temperature. Vital to a car's overall temperature, radiator caps work as a membrane for your car's radiator and act as valves that enclose the radiator and catch excessive fluid coolant. Radiator caps are used on all gas and diesel engines including those found on cars, trucks, and heavy-duty construction and agricultural equipment.
