Tools Required

Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

1. Disconnect the battery negative cable from the battery.



2. Remove fan shrouds from the radiator. Refer to Fan Shroud Replacement .
3. Rotate the engine until the timing marks on the crankshaft balancer and the engine front cover are on TDC.
4. Remove the drive belt from the vehicle. Refer to Drive Belt Replacement .
5. Raise the vehicle and support with safety stands. Refer to Lifting and Jacking the Vehicle in General Information.



6. Remove the crankshaft balancer from the crankshaft. Refer to Crankshaft Balancer Replacement .



7. Remove the water pump from the engine block. Refer to Water Pump Replacement in Engine Cooling.



8. Remove the engine front cover from the engine block. Refer to Engine Front Cover Replacement .



9. Aligned the timing marks on the camshaft and crankshaft gears.

Important: If the crankshaft position reluctor ring is removed, a new crankshaft position reluctor ring sensor must be installed.




10. Remove the crankshaft position reluctor ring. Refer to Crankshaft Position Sensor Reluctor Ring Replacement .



11. Remove the camshaft sprocket retaining bolts.
12. Remove the timing chain and camshaft sprocket.



13. Use the J 28509-A to remove the crankshaft sprocket.

Important: When installing the timing chain and sprockets to the engine block, check to ensure the timing marks are aligned, the dowel pin and the camshaft sprocket are properly aligned, and the sprockets and the chain mesh properly.

Tools Required

J 22102 Crankshaft Sprocket Installer

1. Use the J 22102 to install the crankshaft sprocket.



2. Install the timing chain and sprocket to the camshaft.

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 camshaft retaining bolts to the camshaft.

Tighten
