Tools Required

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. Partially drain the coolant from the radiator. Refer to Cooling System Draining and Filling in Engine Cooling.
3. Remove the intake manifold sight shield.

14. Remove the camshaft seal.



15. Remove the cam cover screws.



16. Remove the cam cover by moving the cam drive end of the cover up.



17. Pivot the entire cover around the water pump drive shaft.



18. Move the cover upward and pivoting such that the edge of the cover closely follows the left edge of the intake manifold cover.
19. Discard the cover seal if there is any evidence of damage or if the seal comes out of the groove in the cover during removal. The spark plug seals may be reused if undamaged.

1. Install the spark plug and cam cover seals as required.



2. Insert the intake cam through the hole in the cam cover and using your fingers.

Important: Be careful to prevent the exposed section of the cam cover seal from being damaged by the edge of the cylinder head casting.




3. Guide the cam cover up over the edge of the cylinder head.



4. Work the cover into position by allowing the top edge of the cover to follow the left side edge of the intake manifold.




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.
