ACDelco RC96 GM Original Equipment 15 PSI Radiator Cap

The ACDelco RC96 is a GM Original Equipment radiator cap designed to maintain proper cooling system pressure at 15 PSI. This pressure cap is engineered to GM's exacting specifications to ensure reliable performance and proper cooling system operation.

Key Features:

• 15 PSI pressure rating for optimal cooling system performance
• GM Original Equipment quality and direct fit design
• Precision-engineered pressure and vacuum relief valves
• Prevents coolant loss and system over-pressurization
• Helps raise coolant boiling point for improved engine protection

This radiator cap performs the critical function of sealing the cooling system while allowing pressure relief when needed. The pressure valve opens at 15 PSI to prevent over-pressurization, while the vacuum valve allows coolant to return from the overflow reservoir during cool-down. As a GM Original Equipment part, the RC96 meets the same standards as the cap that came with your vehicle from the factory.
