Installation Procedure

    Object Number: 217369 Size: SH

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  1. Install the coolant pump (1) with a new gasket (2) to the engine. Secure the pump with five bolts.

    2. Tighten
    Tighten the coolant pump bolts to 12 N·m (106 lb in).

  2. Install the rubber seals between the coolant pump and the oil pump.
  3. Install the rubber seals between the coolant pump and the cylinder head.
  4. Connect the engine oil level indicator tube to the engine. Secure the engine oil level indicator tube with a mounting bolt. Do not tighten fully.

    5. Tighten
    Tighten the engine oil level indicator tube mounting bolt to 11 N·m (97 lb in).

  5. Install the timing belt tensioner and pulley. Refer to Timing Belt Tensioner Replacement in Engine Mechanical-1.6 Liter L4.
  6. Install the timing belt. Refer to Timing Belt Replacement in Engine Mechanical-1.6 Liter L4.

    7. Object Number: 167701 Size: MH
  7. Install the crankshaft pulley (3). Secure the crankshaft pulley with five bolts.

    8. Tighten
    Tighten the crankshaft pulley bolts to 16 N·m (12 lb ft).


    Object Number: 167718 Size: SH
  8. Position the generator/coolant pump drive belt (2) on the pulley (1) before installing the coolant pump pulley (1).
  9. Install the coolant pump pulley (1) to the coolant pump shaft.

    10. Important: The fan clutch, cooling fan and radiator shroud must be installed together because of insufficient clearance to install these parts in separate steps.

  10. Install the fan clutch, cooling fan and shroud together.
  11. Secure the fan clutch (4), cooling fan (3) and shroud with the four fan clutch nuts and the four shroud bolts.

    12. Tighten

        • Tighten the fan clutch nuts to 11 N·m (97 lb in).
        • Tighten the shroud bolts to 11 N·m (97 lb in).

    Object Number: 167701 Size: MH
  12. Adjust the air conditioner compressor drive belt (if equipped).

    13. Object Number: 167701 Size: MH
  13. Adjust the generator/coolant pump drive belt tension (1) so that the belt deflects 5 to 8 mm (0.02 to 0.32 in) under 10 kg (22 lbs) of applied pressure.

    14. Tighten
    Tighten the generator upper mounting bolt to 27 N·m (20 lb ft) while holding the generator/coolant pump drive belt tension.

  14. Fill the radiator will an approved coolant. Refer to Cooling System Draining and Filling .
  15. Install the radiator cap to the radiator.
  16. Reposition the A/C flexible hose to the radiator. Secure with the two bolts.

    17. Tighten
    Tighten the air conditioning flexible hose bolts to 15 N·m (11 lb ft).
