The radiator cap usually has a specific pressure rating to prevent leakage and potential system damage caused by expansion under high pressure due to heat during engine operation. Therefore, the radiator cap functions to adjust pressure and prevent overflow. To maintain appropriate pressure and temperature while the engine is operating, the radiator cap is an essential part. As a radiator cap manufacturer and supplier, Guide Win’s radiator caps come in various specifications and styles, including a warning mark sticker and a safety lever to assist in pressure discharge, thus meeting diverse user needs.
