Caps that do more than just close.
Radiator caps do more than just fill the vehicle radiator opening. They ensure optimal system pressure at all times during operation by allowing air to escape in case of overpressure, while preventing blowout. Therefore, they are one of the smallest but most important parts in keeping vehicle cooling systems operating efficiently.
