5. Radiator Cap
A: INSPECTION
1) Attach radiator cap to tester.
2) Increase pressure until tester gauge pointer stops.

2,11—14 psi)
Service limit pressure:
69 kPa (0.7 kg/cm
2, 10 psi)
CAUTION:
Be sure to remove foreign matter and rust from the cap
in advance; otherwise, results of pressure test will be
incorrect.
