Important: All gaskets surfaces are to be free of oil or other foreign material during assembly.
1. Install the water pump and NEW gaskets.
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.
