Radiator Cap Opening Pressure Check
WARNING: This page is about a different car, the 2008 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Be sure that the cap is clean before testing. Rust or other foreign material on the cap seal will cause an improper reading.
- Use a cap adapter to attach the cap to the tester.
- Increase the pressure until the indicator of the gauge stops moving.
Minimum limit: 83 kPa (12 psi)
Standard value: 93 - 123 kPa (14 - 18 psi)
- Replace the radiator cap if the reading does not remain at or above the limit.
