Detailed Product Description

The Dorman 902-0065 engine coolant reservoir cap is engineered to maintain the correct pressure within the cooling system, preventing coolant loss and overheating. Its plastic construction offers resistance to corrosion and heat, while the black finish complements the engine bay. The 76.2 mm diameter and threaded twist design provide a secure and tight seal, essential for pressurized cooling systems. Rated for up to 18 psi, this cap helps maintain optimal system pressure, which is critical for efficient engine cooling and performance. The absence of a pressure release lever and venting means it is designed for sealed systems that rely on precise pressure control.

Common Applications and Issues Addressed

Installation Notes and Tips

Ensure the engine is cool before removing the old coolant reservoir cap to avoid injury from hot coolant or steam. Align the threaded cap properly and twist until securely tightened to maintain system pressure. Regular inspection of the cap and cooling system is recommended to detect wear or damage early. This cap is compatible with vehicles that specify a 76.2 mm diameter, threaded, twist-type engine coolant reservoir cap.
