CSF 4514 Radiator Pressure Cap Micro 16 PSI

The CSF 4514 is a premium micro-style radiator pressure cap rated at 16 PSI, designed to maintain optimal cooling system performance. This high-quality pressure cap is engineered to fit a wide range of modern vehicle applications, particularly newer Japanese and domestic vehicles that utilize the micro cap design.

Key Features:

• 16 PSI pressure rating for optimal cooling system performance
• Micro cap design for modern vehicle applications
• Dual spring-loaded valve system regulates pressure and vacuum
• Constructed from premium materials for durability and reliability
• Meets or exceeds all OE and industry standards
• Cross-references to Stant 10242 and 33049

How It Works:

When cooling system pressure exceeds the 16 PSI rating, the spring-loaded valve releases coolant into the overflow tank to maintain optimal pressure. As the engine cools, a second spring-loaded valve creates a vacuum that draws coolant back from the overflow tank, preventing air pockets and protecting hoses from collapse due to external air pressure.

CSF, known as "The Cooling Experts," manufactures cooling system components in ISO-certified facilities with rigorous quality testing. Always inspect your radiator cap for wear and tear when servicing your cooling system, and replace with a quality pressure cap like the CSF 4514 to ensure proper cooling system operation.
