Mopar Performance Radiator Cap

The Mopar Performance radiator cap is a replacement cooling system cap built to original-equipment quality. It seals the radiator filler neck and holds the cooling system at its rated pressure. A cap that holds pressure properly helps the coolant resist boiling, so the engine runs at stable operating temperatures.

Key Features:

• Original equipment-quality construction from Mopar Performance
• Pressure-relief design that vents excess pressure and helps prevent coolant overflow
• Seals the radiator filler neck to keep coolant in the system
• Simple replacement of a worn, leaking or aging radiator cap, with no modifications needed

Radiator caps wear over time. A cap that is more than about ten years old, or that looks worn, is a good candidate for replacement. Choose the pressure rating and style that match your cooling system. Mopar Performance has a long history in Chrysler, Dodge, Jeep and Ram performance parts. Use this product line to refresh a stock cooling system or to maintain a performance build.
