1. Install the coupling to the water pump shaft with the groove on the coupling toward the engine block. Apply a light coat of grease to the new O-ring seals and the coupling.
2. Position the water pump and new gaskets to the engine block. Make sure that the tabs are straight up.
3. If necessary, rotate the coupling in order to align it to the water pump driveshaft splines and then seat the water pump.
4. Install the water pump bolts.

Tighten
Tighten the water pump bolts to 45 N·m (33 lb ft).

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.
