  2. Apply a pressure of 93 ~ 123 kPa (0.95 ~ 1.25 kgf/cm2 , 14 ~ 19 psi).
  3. Inspect for engine coolant leaks and a drop in pressure.
  4. If the pressure drops, check hoses, the radiator and the water pump for leakage. If there is no leakage, inspect the heater core, the cylinder block and the cylinder head.
  5. Remove the tester and reinstall the radiator cap.
    NOTE: Check for engine oil in coolant and/or coolant in engine oil.
