1. Raise the vehicle.
2. Remove the oil filter from the engine block (4 wheel drive shown).



3. Remove the drain plug from the oil pan.

Important: When performing an oil filter and oil change on a 6.5L diesel engine, use only 8 quarts of oil. This will bring the oil level between "ADD" and "FULL", which is normal. Start the vehicle and wait until the engine reaches normal operating temperature. Shut the vehicle off and wait a minimum of 15 minutes before checking the oil level. It should read "Full" or very close to "Full". Do not check the oil level when the engine is cold, a false reading will occur.

Important: When serving a four wheel drive model equipped with a 6.5L turbocharger diesel engine, retighten the oil filter adapter bolt to 65 N·m (47 lb ft) after installing a new oil filter.

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.
