RADIATOR CAP INSPECTION
• Fit the cap 1 to the radiator cap tester 2.
• Build up pressure slowly by operating the tester. Make sure
that the pressure build-up stops at 95 – 125 kPa (0.95 – 12.5
kgf/cm², 13.5 – 17.8 psi) and that, with the tester held stand-
still, the cap is capable of holding that pressure for at least 10
seconds.
• Replace the cap if it is found not to satisfy either of these two
requirements.
