Information:
Steam or hot coolant can cause severe burns.Do not loosen the filler cap or the pressure cap on a hot engine.Allow the engine to cool before removing the filler cap or the pressure cap.

9S-8140 Pressurizing Pump (3) Release valve (4) 2P-2329 Adapter As (5) HoseThe 9S-8140 Pressurizing Pump is used to test the cooling system for leaks. The pump can also be used to test the cap assembly, the pressure relief valve, and the pressure gauge.To check for the amount of pressure that opens the cap assembly, use the following procedure:
After the engine cools, carefully loosen the cap assembly in order to release the pressure from the cooling system. Remove the cap assembly.
Carefully inspect the cap assembly. Look for any damage to the seals and to the sealing surface.Remove any deposits that are found.If the cap assembly is damaged, obtain a new cap assembly.
Install the cap assembly on the 9S-8140 Pressurizing Pump by using the 2P-2329 Adapter As .The opening pressure for the cap assembly's pressure relief valve is stamped on the cap assembly.
Apply pressure to the cap assembly. Compare the gauge reading with the opening pressure that is listed on the cap assembly.If the cap assembly cannot sustain the correct pressure, obtain a new cap assembly.If the cap assembly's pressure relief valve does not open within approximately 7 kPa (1 psi) of the pressure that is stamped on the cap assembly, obtain a new cap assembly.Testing The Radiator And Cooling System For Leaks
Steam or hot coolant can cause severe burns.Do not loosen the filler cap or the pressure cap on a hot engine.Allow the engine to cool before removing the filler cap or the pressure cap.

Tools Needed Qty
9S-8140 Pressurizing Pump 1 Use the following procedure in order to check the cooling system for leaks:
After the engine cools, carefully loosen the filler cap in order to release the pressure from the cooling system. Remove the filler cap.
Ensure that there is a sufficient amount of coolant in the expansion tank.
Install the 9S-8140 Pressurizing Pump onto the filler tube.
Increase the pressure reading on the gauge to 20 kPa (3 psi) more than the pressure on the filler cap.
Inspect the radiator, all connection points, and the hoses for leaks.If no leaks are found and the gauge reading remains steady for a minimum of five minutes, the cooling system is not leaking.If leaking is observed and/or the gauge reading decreases, make repairs, as needed.
