- Inspect the pressure relief cap and seals for damage or deterioration. Install a new pressure relief cap if necessary.
- Fit the pressure relief cap to the Radiator/Heater Core Pressure Tester Kit using the correct adapter.
- 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 the pressure and repeat the test. Install a new pressure relief cap if the pressure is not within specification. Refer to GENERAL SPECIFICATIONS table.
