Installation Procedure


  1. Install the water pump gasket (2).
  2. Install the water pump (1).


    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.


  3. Install the water pump bolts. Tighten

    Tighten the bolts to 10 N·m (89 lb in).

  4. Install the water pump pulley.
  5. Install the water pump pulley bolts. Tighten

    Tighten the bolts to 25 N·m (18 lb in).

  6. Install the drive belt.
  7. Install the drive belt shield.
  8. Install the drive belt shield bolt. Tighten

    Tighten the bolt to 10 N·m (89 lb in).

  9. Fill the cooling system.

While you are at it, you might want to replace the coolant, if it has not been done in a while (the last 2 years).

That's about it. If you have the time and the tool, this is not that difficult.
