What It Helps Address

Installation Notes and Tips

Verify the radiator neck style and pressure specification before installation. Clean the sealing surface on the radiator or coolant reservoir neck, then install the cap fully so the cam-on mechanism engages correctly. After installation, check for leaks and confirm normal coolant level and operating temperature. For fitment confirmation, match the vehicle year, make, model, and position listed for RC0193.
