WATER PUMP INSTALLATION


  1. INSTALL WATER PUMP ASSEMBLY


    1. A01CH6IE03

      Apply a continuous bead of seal packing (diameter 1.5 to 2.5 mm (0.06 to 0.10 in.)) as shown in the illustration.

      Seal packing
      Toyota Genuine Seal Packing Black, Three Bond 1207B or equivalent

      Note


      • Remove any oil from the contact surface.

      • Install the water pump within 3 minutes of applying the seal packing.

      • Do not start the engine for at least 2 hours after the installation.

    2. A01CIV9

      Install the water pump assembly with the 8 bolts.

      Torque:
      29 N*m  { 290 kgf*cm, 21 ft.*lbf }

  2. INSTALL FAN PULLEY


    1. A01CI13

      Install the fan pulley.

  3. INSTALL FAN


    1. Temporarily install the fan with the 4 nuts.

    2. Install the fan and generator V belt Click here.

    3. Holding the V belt, tighten the 4 nuts completely to install the fan pulley and fan properly.

      Torque:
      29 N*m  { 291 kgf*cm, 21 ft.*lbf }

  4. INSPECT DRIVE BELT


    1. A01CHS3E01

      Check the fan and generator V belt deflection.

      Tech Tips

      The specified deflection values per belt are shown in the following table.

      Deflection
      Item Specified Condition
      New belt 10.5 to 12.5 mm (0.41 to 0.49 in.)
      Used belt 12.5 to 16.0 mm (0.49 to 0.63 in.)

      Note


      • Check the V belt deflection at the specified point.

      • When inspecting a belt which has been used for over 5 minutes, apply the used belt specifications.

  5. INSTALL RADIATOR HOSE INLET


    1. A01CIUI

      Install the radiator hose inlet with the 2 clips.

  6. ADD ENGINE COOLANT


    1. Add engine coolant.

      Specified capacity
      14.7 liters (15.5 US qts, 12.9 Imp. qts)

      Note

      Never use water as a substitute for engine coolant.

      Tech Tips


      • TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to the engine cooling system and other technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology consists of a combination of low phosphates and organic acids).

      • Contact your TOYOTA dealer for further details.

    2. Check the coolant level inside the radiator by squeezing the inlet and outlet radiator hoses several times by hand. If the coolant level goes down, add coolant.

    3. Install the radiator cap.

    4. Slowly pour coolant into the radiator reservoir until it reaches the FULL line.

    5. Bleed air from the cooling system.


      1. Warm up the engine until the thermostat opens.

        While the thermostat is open, circulate the coolant for several minutes.

      2. Press the inlet and outlet radiator hoses several times by hand to bleed air.

        Note


        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

    6. Stop the engine and wait until the coolant cools down.

    7. Remove the radiator cap and check the coolant level.

    8. If the coolant level has dropped, add coolant.

    9. Check the coolant level inside the radiator reservoir tank again. If it is below the full level, add coolant.

  7. INSPECT FOR COOLANT LEAK


    1. Remove the radiator cap.

      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.

    2. A01CIGLE01

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

    3. Warm up the engine.

    4. 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.

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

    5. Install the radiator cap.
