TESTING RADIATOR AND COOLANT BOTTLE CAPS
WARNING: NEVER PRESSURIZE A COOLING BOTTLE CAP OR RADIATOR CAP BEYOND ITS MAXIMUM SPECIFIED PRESSURE.
1. Carefully remove the radiator or coolant bottle cap. Check manufacturer's service information
and the cap to ensure the pressure cap fitted has the correct pressure rating for the vehicle's
cooling system.
2. Clean the pressure cap gasket and ensure it is in good condition. Determine which cap adapter is
correct for the cap to be tested. On new caps, wet the rubber gasket with water. Install the cap to
the adapter. See Figure 7 and 8.
NOTE: If you are testing a new cap, it may be necessary to install and remove the cap several times
to properly seat the new gasket. Do this on the vehicle.
3. Position the quick-connect fitting at the end of the pump hose over the fitting on the test adapter
and press down. Make sure the coupling is fully engaged.
4. Hold the tester with the cap and adapter hanging down. Operate the pump and watch the
pressure gauge. Compare the reading on the gauge when the cap releases pressure to the
pressure specified in the service information or on the cap.
5. Disconnect the fitting and separate the pump and adapter. Remove the cap from the adapter. Clean and
dry these components and store them in their proper locations. Replace the radiator cap.
