  1. Remove the coolant filler tank cap, fill the coolant filler tank with engine coolant, then install the tester to the installation position of the cap.
  2. Apply a pressure of 122 kPa (1.2 kg/ 2 , 18 psi) to the radiator and check the following points: Leakage from the radiator or its vicinity Leakage from the hose or its connections CAUTION: Inspection must be carried out at the side of coolant filler tank, not at the side of radiator. Engine should be turned off. Wipe engine coolant from check points in advance. Be careful of the spurt of engine coolant when removing the tester. Be careful not to deform the filler neck of the coolant filler tank when installing and removing the tester.

  1. Attach the radiator cap to tester.
  2. Increase pressure until the tester gauge pointer stops. Radiator cap is functioning properly if it holds the service limit pressure for five to six seconds. Coolant filler tank side Specified pressure: 93 - 123 kPa (0.95 - 1.25 kg/ 2 , 14 - 18 psi) Service limit pressure: 83 kPa (0.85 kg/ 2 , 12 psi) Radiator side Specified pressure: 122 - 152 kPa (1.24 - 1.55 kg/ 2 , 18 - 22 psi) Service limit pressure: 112 kPa (1.14 kg/ 2 , 16 psi) CAUTION: Be sure to remove foreign matter and rust from the cap in advance. Otherwise, results of pressure test will be incorrect. Do not confuse the cap of coolant filler tank and cap of radiator.
