      Tech Tips

      Before starting the engine to warm up the engine, turn the A/C switch off.


      1. Put the engine in inspection mode Click here.

      2. While idling the engine for approximately 10 minutes, make sure the coolant remains at the FULL line by adding coolant as necessary.

      3. A01H0PS

        After idling the engine for 10 minutes, add coolant until it reaches the B line.

        Capacity

        CAUTION:


        • Wear protective gloves.

        • Be careful as the radiator hose is hot.

        • Keep your hands away from the radiator fan.

        Tech Tips

        The thermostat open timing can be confirmed by pressing the No. 1 radiator hose by hand, and checking when the SLLC starts to flow inside the hose.

    8. Stop the engine and wait until the coolant cools down to ambient temperature.

    9. Check the coolant level.

      If the coolant level is below the FULL line, add coolant until it reaches the FULL line.

  5. INSPECT FOR COOLANT LEAK

    CAUTION:

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

    Note

    Before each inspection, turn the A/C switch OFF.


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

    2. Warm up the engine.

    3. Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm2, 17 psi), and check that the pressure does not drop.

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