CSF Radiator Pressure Cap

The CSF radiator pressure cap (also called a radiator cap or coolant pressure cap) keeps your cooling system sealed and pressurized so the engine stays at a stable operating temperature. CSF supplies pressure caps to OEM and aftermarket customers worldwide. The range comes in several cap sizes and pressure ratings that cover most applications, and the caps are built to meet or exceed OE and industry standards.

Key Features:

• Spring-loaded pressure valve that vents excess coolant to the overflow tank when system pressure rises above the cap's rating
• Second spring-loaded vacuum valve that draws coolant back from the overflow tank as the engine cools
• Helps prevent air pockets in the radiator and keeps hoses from being crushed by external air pressure when the system cools
• Built from high-strength materials for durable, long-lasting service
• OE-style replacement design for straightforward installation

A good pressure cap helps hold coolant in the radiator and keeps temperatures under control. Replace a worn cap with one that has the correct pressure rating for your cooling system.
