ВЕНТИЛЯТОР СИСТЕМЫ ОХЛАЖДЕНИЯ ПРОВЕРКА БЕЗ СНЯТИЯ С АВТОМОБИЛЯ

  1. CHECK COOLING FAN OPERATION AT LOW TEMPERATURES (Below 94°C (201°F))

    1. Turn the engine switch on (IG) with the A/C switch off.

    2. A005SD1

      Check that the cooling fan stops.

      If it does not, check the cooling fan relays and engine coolant temperature sensor, and then check for disconnection of the connector or a wire break between the cooling fan relay and engine coolant temperature sensor.

    3. A005UY8

      Disconnect the engine coolant temperature sensor connector.

    4. A005TPW

      Check that the cooling fan rotates.

      If it does not, check the fuses, cooling fan relays, ECM and cooling fan, and then check for an open circuit between the cooling fan relay and engine coolant temperature sensor.

    5. Reconnect the engine coolant temperature sensor connector.

  2. CHECK COOLING FAN OPERATION AT HIGH TEMPERATURES (Higher than 96°C (205°F))

    1. Start the engine and raise the coolant temperature to higher than 96°C (205°F).

      Tech Tips

      Coolant temperature is the value detected by the engine coolant temperature sensor on the cylinder head.

    2. Check that the A/C switch is off.

    3. A005TPW

      Check that the cooling fan rotates.

      If it does not, check the engine coolant temperature sensor, cooling fan, harness or connector.
