  1. Clean and dry the pump mating surfaces. Install a new by-pass hose to the engine.

This component is subjected to constant high pressure from hot fluid and must be sealed correctly or it will leak.

  1. Install a new gasket and install the water pump to the engine.
  2. Install any bolts that do not retain a bracket.
  3. Tighten the bypass hose clamps. Install the heater hose.
  4. Install the water pump to compressor front mount bolts and bracket, if it was removed.
  5. Install all remaining brackets and components that were removed. Torque all water pump retaining bolts that do not go through adjusting slots to 30 ft. lbs. (41 Nm).
  6. Install the air conditioning compressor pulley and field coil assembly, if it was removed. Install and adjust the alternator/air conditioning or idler belt(s). If applicable, place the remaining belts over their components.
  7. Install the fan blade, spacer or viscous drive unit, pulley and bolts along with the shroud.
  8. Install the radiator, lower hose and shroud.
  9. Adjust the belt(s) and tighten the remaining water pump retaining bolts to 30 ft. lbs. (41 Nm).
  10. Fill the radiator with coolant. This cooling system is self-bleeding, so system bleeding is not required.

  12. Once the vehicle has cooled, recheck the coolant level
