Removal of water pump¶

(See Water pump)

1. Drain engine coolant. (See Replacement of engine coolant › Drainage of engine coolant)
2. Disconnect radiator hose from water inlet.

3. Remove timing belt.

   • 3S-GTE – (See Timing belt (3S-GTE), steps 1–25)
   • 5S-FE – (See Timing belt (5S-FE), steps 1–21)

4. (5S-FE) Remove A/C compressor idler pulley. (See steps 31 (b) to (d) on Cylinder block (5S-FE) › Removal of engine)

5. Remove No.2 idler pulley.

   • 3S-GTE – (See Timing belt (3S-GTE) › Removal of timing belt, step 27)
   • 5S-FE – (See Timing belt (5S-FE) › Removal of timing belt, step 23)

6. (5S-FE) Remove timing belt tension spring.

7. (3S-GTE) Remove oil cooler. (See Engine tune-up › Adjusting shim selection using chart (5S-FE), steps 7–10)

8. Remove water pump and water pump cover assembly.

   1. Remove the two nuts holding the water pump to the water by-pass pipe.

      

   2. Remove the three bolts in the sequence shown.

      

   3. Pull out the water pump together with the water pump cover.

   4. Remove the gasket and two O-rings from the water pump and water by-pass pipe.

      

9. Separate water pump and water pump cover.

   Remove the three bolts, water pump and gasket from the water pump cover.

10. Remove water inlet and thermostat from water pump cover. (See Thermostat, step 4)

Inspection of water pump¶

Inspect water pump¶

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

Installation of water pump¶

(See Water pump)

1. Install thermostat and water inlet to water pump cover. (See Thermostat › Installation of thermostat, steps 1, 2)

2. Assemble water pump and water pump cover.

   Install a new gasket and the water pump to the pump cover with the three bolts.

   Torque: 95 kg-cm (82 in.-lb, 9.3 N·m)

   

3. Install water pump and water pump cover assembly.

   1. Install new O-ring and gasket to the water pump cover.

      

   2. Install a new O-ring to the water by-pass pipe.

      

   3. Apply soapy water to the O-ring on the water by-pass pipe.

      

   4. Connect the pump cover to the water by-pass pipe. Do not install the nuts yet.

   5. Install the water pump with the three bolts. Tighten the bolts in the sequence shown.

      Torque:

      • 3S-GTE – 80 kg-cm (69 in.-lb, 8.0 N·m)
      • 5S-FE – 95 kg-cm (82 in.-lb, 9.3 N·m)

      

   6. Install the two nuts holding the water pump cover to the water by-pass pipe.

      Torque:

      • 3S-GTE – 120 kg-cm (9 ft-lb, 12 N·m)
      • 5S-FE – 95 kg-cm (82 in.-lb, 9.3 N·m)

      

4. (3S-GTE) Install oil cooler. (See Oil cooler (3S-GTE) › Installation of oil cooler, steps 2–5)

5. (5S-FE) Install timing belt tension spring.

6. Install No.2 idler pulley.

   • 3S-GTE – (See Timing belt (3S-GTE) › Installation of timing belt, step 3)
   • 5S-FE – (See Timing belt (5S-FE) › Installation of timing belt, step 3)

7. (5S-FE) Install A/C compressor idler pulley. (See step 13 (b) to (e) on Cylinder block (5S-FE) › Installation of engine)

8. Install timing belt.

   • 3S-GTE – (See Timing belt (3S-GTE) › Installation of timing belt, steps 5–32)
   • 5S-FE – (See Timing belt (5S-FE) › Installation of timing belt, steps 5–26)

9. Connect radiator hose to water inlet.

10. Fill with engine coolant. (See Replacement of engine coolant › Refill of engine coolant)
