НАСОС СИСТЕМЫ ОХЛАЖДЕНИЯ ПРОВЕРКА БЕЗ СНЯТИЯ С АВТОМОБИЛЯ


  1. REMOVE FAN SHROUD


    1. A009525

      Loosen the 4 nuts holding the fluid coupling fan.

    2. Remove the vane pump V belt and the fan and generator V belt Click here.

    3. A00971T

      Remove the 2 bolts holding the fan shroud.

    4. Remove the 4 nuts of the fluid coupling fan, and then remove the shroud together with the coupling fan.

      Note

      Be careful not to damage the radiator core.

    5. Remove the fan pulley from the water pump.

  2. INSPECT WATER PUMP ASSEMBLY


    1. A0096N8E01
      Text in Illustration
      *1 Air Hole

      Visually check the air holes for coolant leakage.

      If leakage is found, replace the water pump assembly.

    2. Turn the pulley, and check that the pump bearing moves smoothly and quietly.

      If the bearing moves roughly or noisily, replace the water pump assembly.

  3. INSPECT FLUID COUPLING ASSEMBLY


    1. A009B8U

      Remove the 4 nuts and fan.

    2. A0098RI

      Check the fluid coupling for damage or silicon oil leaks. If necessary, replace the fluid coupling.

    3. Install the fan with the 4 nuts.

      Torque:
      6.5 N*m  { 66 kgf*cm, 58 in.*lbf }

  4. INSTALL FAN SHROUD


    1. Install the fan pulley to the water pump.

    2. Install the shroud together with the coupling fan between the radiator and engine.

      Note

      Be careful not to damage the radiator core.

    3. Temporarily install the fluid coupling fan to the fan pulley with the 4 nuts. Tighten the nuts as much as possible by hand.

    4. A009713

      Attach the claws of the shroud as shown in the illustration.

    5. Install the shroud with the 2 bolts.

      Torque:
      5.0 N*m  { 51 kgf*cm, 44 in.*lbf }

    6. Install the fan and generator V belt and vane pump V belt Click here.

    7. Tighten the 4 nuts of the fluid coupling fan.

      Torque:
      19 N*m  { 189 kgf*cm, 14 ft.*lbf }
