Water Pump Replacement L36

1. Disconnect the negative battery cable. Refer to

   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.

   in General Information.
2. Drain the coolant. Refer to Cooling System Draining and Filling .
3. Remove the accessory drive belt. Refer to Accessory Drive Belts Replacement (VIN K) in Engine Mechanical.



4. Remove the water pump pulley bolts.
5. Remove the water pump pulley.
6. Clean the gasket mating surfaces.

1. Using a new gasket, install the water pump on the engine.

Tighten

•	Tighten the bolts (1) to 15 N·m (11 lb ft).

•	Tighten the bolts (2) to 30 N·m (22 lb ft).




2. Install the water pump bolts.

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 accessory drive belt. Refer to Accessory Drive Belts Replacement (VIN K) in Engine Mechanical.
4. Fill the coolant. Refer to Cooling System Draining and Filling .
5. Connect the negative battery cable.
6. Check for coolant leaks.
