Radiator Cap

1. Inspect the radiator cap and seals for damage or deterioration. Replace the radiator cap if necessary.





2. Fit radiator cap to Radiator/Heater Core Pressure Tester Kit using the aftermarket adapter.





3. Note: If the plunger of the pressure tester is depressed too fast, an incorrect pressure reading will result.

Slowly pump the pressure tester until the pressure gauge stops increasing and note the highest pressure reading. Release pressure and repeat test. Replace radiator cap if the pressure is not 99.3-121.4 kPa (14.4-17.6 psi).
