### Removal Procedure

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. Disconnect the secondary spark plug wires (1).

Move the wires to the side.

3. Remove the spark plugs.
4. Rotate the engine to top dead center on the number one cylinder.
5. Remove the two timing chain tensioner bolts (1, 2).
6. Remove the timing chain tensioner.

### Installation Procedure

1. Release the ratchet pawl.
2. Fully depress the plunger (4).

Apply the hook (2) to the pin (3).

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 timing chain tensioner into the timing chain cover. Secure the timing chain tensioner using two bolts (1).

Tighten
Tighten the timing chain tensioner bolts to 10 N·m (89 lb in).

4. Rotate the engine approximately one revolution in order to release the plunger on the timing chain tensioner.
5. Install the spark plugs.

Tighten
Tighten the spark plugs to 28 N·m (21 lb ft).

6. Connect the secondary spark plug wires.
7. Connect the negative battery cable.
