Installation Procedure






1. Lubricate the CKP sensor O-ring with clean engine oil.

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.

2. Install the CKP sensor in the engine block and attachment bolt.

Tighten
Tighten the crankshaft position sensor bolt to 10 Nm (89 lb in).

3. Connect the CKP sensor harness connector. Push in the connector until a slick is heard, then pull back to confirm a positive engagement.
4. Install the starter into the flywheel housing and align the bolt holes.






5. Install the upper and lower starter assembly to the engine block bolts.

Tighten
Tighten the starter-to-engine bolts to 40 Nm (30 lb ft).

6. Install the 2 starter solenoid harness connections and attachment nuts.

Tighten
- Tighten the B+ cable to starter nut (large) to 10 Nm (89 lb in).
