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

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

    2. Install the engine water pump assembly with the 8 bolts.

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


    1. Install the fan pulley to the engine water pump assembly.

  3. INSTALL FAN


    1. Temporarily install the fan with the 4 nuts.

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

    3. Tighten the 4 nuts.

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


    1. Check the V belt for wear, cracks or other signs of damage.

      If any of the following defects is found, replace the V belt.


      • The V belt is cracked.

      • The V belt is worn out to the extent that the cords are exposed.

      • The V belt has chunks missing from the ribs.

    2. Check that the V belt fits properly in the ribbed grooves.

      Tech Tips

      Check with your hand to confirm that the V belt has not slipped out of the groove on the bottom of the pulley. If it has slipped out, replace the V belt. Install the V belt correctly.

      *1 Fan Pulley
      *2 Generator
      *3 Crankshaft Pulley

      Check the fan and generator V belt deflection.

      Standard Deflection
      Item Specified Condition
      New belt 10.5 to 12.5 mm (0.413 to 0.492 in.)
      Used belt 12 to 13 mm (0.472 to 0.512 in.)

      Note


      • Check the V belt deflection at the specified point.

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

      Tech Tips

      When inspecting the V belt deflection, apply 98 N (10 kgf, 22 lbf) of tensile force to it.

      *1 Idler Pulley
      *2 A/C Compressor
      *3 Crankshaft Pulley

      Check the No. 1 V (cooler compressor to crankshaft pulley) belt deflection.

      Standard Deflection
      Item Specified Condition
      New belt 7 to 9 mm (0.276 to 0.354 in.)
      Used belt 8.5 to 10 mm (0.335 to 0.394 in.)

      Note


      • Check the V belt deflection at the specified point.

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

      Tech Tips

      When inspecting the V belt deflection, apply 98 N (10 kgf, 22 lbf) of tensile force to it.

  5. INSTALL INLET RADIATOR HOSE


    1. Install the inlet radiator hose and tighten the 2 hose clamps to secure the hose.

  6. ADD ENGINE COOLANT

    CAUTION:

    Do not remove the radiator cap sub-assembly, radiator drain cock plug or engine drain plug while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

    Note

    Do not substitute plain water for engine coolant.


    1. Add engine coolant.

      Standard capacity
      14.2 liters (15.0 US qts, 12.5 Imp. qts)

      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 is a combination of low phosphates and organic acids).

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

    3. Install the radiator cap sub-assembly.

    4. Slowly pour coolant into the radiator reservoir until it reaches the F 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. Maintain the engine speed at a speed between 2500 and 3000 rpm.

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

        Note


        • Wear protective gloves.

        • 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 to ambient temperature.

    7. Remove the radiator cap sub-assembly and check the coolant level.

      If the coolant level has dropped, add coolant.

    8. Check the coolant level inside the radiator reservoir assembly again.

      If the coolant level is below the F line, add coolant to F line.

  7. INSPECT FOR COOLANT LEAK

    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.

    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 137 kPa (1.4 kgf/cm2, 20 psi), and check that the pressure does not drop.

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