STATIC PRESSURE TEST USING DIRECT-FIT ADAPTER ON SYSTEMS WITH A COOLANT RESERVOIR
WARNING: MAKE SURE ADAPTER SEALS FULLY BEFORE THE COOLING SYSTEM IS PRESSURIZED.
1. Carefully remove the threaded cap from the coolant bottle. See
Figure 3.
2. Select an appropriate adapter that fits the threads on the coolant
bottle. Thread the adapter into the coolant bottle until fully seated.
See Figure 4.
3. Connect the quick-connect fitting at the end of the pump hose to
the fitting on the adapter and press down. Make sure the coupling is
fully engaged.
4. Examine the vehicle's service information and coolant bottle cap
to determine the proper system pressure. Pump the handle of the
pressure tester until the needle of the gauge indicates the rated
pressure of the system. See Figure 5.
5. With the system still pressurized, inspect the radiator and cooling
system. Check the points where hoses connect to the radiator and
coolant bottle. Inspect other system components for signs of leakage.
When complete, check the reading on gauge and compare to the rated
pressure of the system.
6. When testing is complete, release the pressure in the system by
slowly turning release valve. Take care as a stream of coolant under
pressure may exit the system through the hose. See Figure 6.
7. Disconnect the quick-connect fitting and separate the pump and
adapter. Clean and dry these components and store them in their
proper locations.
