Gates Radiator Cap

Gates radiator caps are designed to seal and pressurize the engine cooling system. They help maintain the correct operating pressure and keep coolant temperatures stable. Gates is a long-established supplier of cooling system components to the automotive aftermarket. Whether you call it a radiator cap, coolant pressure cap, or radiator pressure cap, this part is a small but essential piece of the system.

Key Features:

• Holds the pressure specified for the cooling system, which raises the coolant boiling point and helps prevent overheating
• Pressure relief valve vents excess pressure and keeps the system from over-pressurizing
• Vacuum valve lets coolant return from the overflow reservoir as the engine cools
• Gasket seals against the filler neck to prevent coolant leaks and loss of pressure
• Built for reliable, repeatable performance across many heat cycles

A worn or weak radiator cap can cause coolant loss, overheating, and collapsed hoses. Replacing it as part of routine cooling system maintenance helps protect the radiator, hoses, and water pump. Choose the child item with the pressure rating and style that match your application.
