### 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. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
3. Remove the oil filter.
4. Verify that the gasket is removed with the filter.
5. Remove the oil filter adapter.
6. Remove the oil filter bypass valve using a screwdriver or a punch in order to pry the valve out.
7. Clean the oil filter mounting surface.

#### Installation Procedure

1. Install the oil filter bypass valve. Seat the valve using a socket of the same diameter and a mallet.

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 oil filter adapter.

Tighten
Tighten the adapter to 29 N·m (21 lb ft).

3. Set the gasket in place and install the filter. Turn the filter ¾-1 complete turn after the gasket contacts the surface of the block.
4. Lower the vehicle.
5. Connect the negative battery cable.
6. Inspect the oil level.
7. Start the vehicle and test for leaks.
