Tools Required

J 38823 Water Pump Drive Pulley Installer

1. Install new spark plugs if required.
2. Install a new camshaft cover seal if required.
3. Place the camshaft cover on the cylinder head using the following procedure:

3.1.	Insert the intake camshaft end through the hole in the end of the camshaft cover.

3.2.	Using your fingers, guide the camshaft cover up over the edge of the cylinder head. Be careful not to damage the exposed section of the camshaft cover seal on the edge of the cylinder head.

3.3.	Work the camshaft cover into position by pivoting the cover down and to the left allowing the cover to clear the camshaft drive chain and then aligning the bolt holes.

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.
