Radiator Caps

Radiator caps are used to keep the fluid in a vehicle's radiator clean and to help manage engine temperature. Radiator caps operate as a membrane for your car's radiator and as valves that enclose the radiator and catch extra fluid coolant, which is critical to its overall temperature. All gas and diesel engines, including those found in vehicles, trucks, and heavy-duty construction and agricultural equipment, need radiator caps.
