Installation

1. Clean gasket mating surfaces.

Water Pump Bolts - Typical:

2. Using a new gasket, install water pump to engine as follows: Guide water pump fitting into bypass hose as pump is being installed. Install water pump mounting bolts. Tighten bolts in a criss-cross pattern to 40 N.m (30 ft. lbs.) torque.

3. Position bypass hose clamp to bypass hose.

4. Spin water pump to be sure that pump impeller does not rub against timing chain case/cover.

Coolant Return Tube - Typical:

5. Install a new O-ring to the heater hose coolant return tube. Coat the new O-ring with antifreeze before installation.

6. Install coolant return tube and its mounting bolt to engine. Be sure the slot in tube bracket is bottomed to mounting bolt. This will properly position return tube.

7. Connect radiator lower hose to water pump.

8. Connect heater hose and hose clamp to coolant return tube.

Fan Blade/Viscous Fan Drive Assembly:

9. Install water pump pulley. Tighten bolts to 27 N.m (20 ft. lbs.) torque. Place a bar or screwdriver between water pump pulley bolts to prevent pulley from rotating.

Automatic Belt Tensioner - Typical:

10. Relax tension from automatic belt tensioner. Install drive belt.

CAUTION: When installing the serpentine accessory drive belt, belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction. The correct belt with correct length must be used.
