7. Radiator Cap
A: INSPECTION
1) Attach the radiator cap to tester.
2) Increase pressure until the tester gauge pointer
stops. Radiator cap is functioning properly if it holds
the service limit pressure for five - six seconds.
Specified 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 pres-
sure test will be incorrect.
