        Tech Tips

        The thermostat open timing can be confirmed by pressing the inlet radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.

    7. A01BBOM

      After the engine cools down, check that the coolant level is between the LOW and FULL level marks.

  18. CHECK FOR ENGINE COOLANT LEAKAGE

    CAUTION:

    Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.


    1. Fill the radiator with coolant and attach a radiator cap tester to the radiator.

    2. Warm up the engine.

    3. Using a radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm2, 19.9 psi), and check that the pressure does not drop.

      Tech Tips

      If the pressure drops, check the hoses, radiator or water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.
