How to Replace the Lubricating Oil and Oil Filter
The oil filter is an integral part of the lubrication system. Proper filter selection and maintenance are important to satisfactory engine performance and service life. The filter is designed to maintain a clean system. It is not capable of cleaning a contaminated system. The maintenance intervals for the appropriate duty cycle are listed in tables in this manual. Scheduled Intervals.
If the used oil is contaminated by fuel or coolant, it may be necessary to take the vehicle to an authorized Detroit™ service outlet. All contaminated oil must be removed from the engine.
Change the engine oil when the engine oil temperature is approximately 60°C (140°F). Changing cold oil will result in extended drain times.
Replace the lubricating oil and oil filter as follows:
- Shut off the engine, apply the parking brake, chock the
wheels, and perform any other applicable safety steps.
- Disconnect the batteries.
- Open the hood.
- Clean the outside of the oil filter housing.
- Unscrew the cap (3) and filter (1), and allow the oil to drain into the housing. After draining is complete, remove the assembly from the housing. Pull straight up to avoid damage to the oil filter stand pipe and bypass valve.
- Remove the filter element (1) by pressing and twisting the side and detaching it from the cap (3).
- Remove the oil filter O-ring (2) and discard it. Lightly coat a new O-ring with clean engine oil and install it on the filter cap.
- Check the filter housing for any debris and remove if necessary.
- Insert a new oil filter element securely into the oil filter cap.
- Insert the oil filter element and cap assembly into the housing. Torque to 25 N·m (18 lb·ft).
- Place a suitable drain container beneath the oil drain plug on the oil pan.
- Remove the oil drain plug (lowest plug on the oil pan), and allow the oil to drain out.
- Install the oil pan drain plug with a new seal washer. Torque to 65 N·m (48 lb·ft).
- Add new engine lubricating oil through the oil fill on the cylinder head cover. Engine Oil Capacities.
- Verify the oil level reading is between the add mark and full mark on the oil dipstick.
- Connect the batteries.
- Always start and operate an engine in a well ventilated area.
- If operating an engine in an enclosed area, vent the exhaust to the outside.
- Do not modify or tamper with the exhaust system or emission control system.
- Start the engine with the accelerator pedal released. Monitor
the oil pressure gauge or indicator lamp. Keep the engine running
at idling speed until oil pressure is present. Do not raise the engine
speed until the proper oil pressure has been reached.
- Check the oil filter housing for signs of leakage.
- Stop the engine. Check the oil level. If necessary, add no more than 4.0 L (4.2 qt.) of oil at a time, until the oil level reaches the full level on the oil dipstick.
- Close the hood.
Warning: PERSONAL INJURY
To avoid injury, never remove any engine component while the engine is running.
Caution: ELECTRICAL SHOCK
To avoid injury from electrical shock, use care when connecting battery cables. The magnetic switch studs are at battery voltage.

Warning: PERSONAL INJURY
Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.
Warning: PERSONAL INJURY
To avoid injury before starting and running the engine, ensure the vehicle is parked on a level surface, parking brake is set, and the wheels are blocked.
Warning: ENGINE EXHAUST
To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic.
Notice: If no oil pressure is shown after approximately 10 seconds, stop the engine and determine the cause. Running the engine with no oil pressure could result in engine damage.
