Radiator Cap: Inspection
WARNING: This page is about a different car, the 2001 Subaru Outback and 2001 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.
- Attach radiator cap to tester.
- Increase pressure until tester gauge pointer stops. Radiator cap is functioning properly if it holds the service limit pressure for five to six seconds.
- Standard pressure: 93 - 123 kPa (0.95 - 1.25 kg/cm2 , 14 - 18 psi)
- Service limit pressure: 83 kPa (0.85 kg/cm2 , 12 psi)
CAUTION: Be sure to remove foreign matter and rust from the cap in advance otherwise, results of pressure test will be incorrect.
