ACDelco GM Original Equipment Radiator Cap

The ACDelco GM Original Equipment Radiator Cap line gives your cooling system a dependable pressure seal. Each cap is built to keep the system at the correct operating pressure. This raises the coolant's boiling point and helps limit coolant loss and overheating. Use these caps when replacing a worn, leaking or damaged radiator cap or coolant reservoir cap.

Key Features:

• Original equipment design from ACDelco, GM's parts brand
• Spring-loaded pressure valve holds system pressure and vents excess pressure when needed
• Vacuum relief valve lets coolant return as the engine cools
• Gasket seal helps prevent leaks at the filler neck
• Offered in several pressure ratings, so you can choose the one that matches your cooling system's requirements

A radiator cap is a small, inexpensive part, and it is a common source of cooling system problems. Replacing it as part of routine cooling system service helps your engine run at its intended temperature. Choose the variant with the pressure rating specified for your application.
