Water Pump: Service and Repair

Coolant Pump Replacement

Removal Procedure

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.






1. Disconnect the negative battery cable.
2. Drain the coolant.
3. Remove the rear timing belt cover.






4. Remove the coolant pump mounting bolts.
5. Remove the coolant pump.
6. Remove the seal ring from the coolant pump.

Installation Procedure






1. Install a new seal ring to the coolant pump.
2. Coat the sealing surface of the seal ring with Lubriplater.

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.

3. Install the coolant pump to the engine block with the flange aligned with the recess of the rear timing belt cover.
4. Install the coolant pump mounting bolts. Tighten the coolant pump mounting bolts to 10 Nm (89 lb in).






5. Install the rear timing belt cover.
6. Fill the engine cooling system.
7. Connect the negative battery cable.
