Radiator Cap: Inspection
WARNING: This page is about a different car, the 2006 Subaru Baja. 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/cm 2 , 14 - 18 psi)
Service limit pressure:
83 kPa (0.85 kg/cm 2 , 12 psi)
CAUTION:
Be sure to remove foreign matter and rust from the cap before installing tester. Otherwise, results of pressure test will be incorrect.
