How to Replace the Lubricating Oil and Oil Filter

How to Replace the Lubricating Oil and Oil Filter - Ops - DD5/DD8

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 should be used to maintain a clean system, not to clean up a contaminated system. The maintenance intervals for the appropriate duty cycle are listed in tables in this manual.

Change the oil and replace the lubricating oil filter as follows:

Note: If the used oil was contaminated by fuel or coolant, it may be necessary to take the vehicle to a certified Detroit Service Center. The Service Center may drain the oil and then remove the oil pan, oil pump, and oil pump intake manifold to drain the remaining oil held back by the backflow valve. It is important to remove all contaminated oil from the engine.
Note: Change the engine oil only when the engine oil temperature is approximately 60°C (140°F). Changing cold oil will result in extended drain times.

    Warning: PERSONAL INJURY

    To avoid injury, never remove any engine component while the engine is running.

  1. Place the transmission in neutral, and set the parking brake.
    2. Notice: Use care to prevent foreign objects from entering the filter housing.
  2. Clean outside of the oil filter housing.
  3. Using a 36-mm socket, unscrew the oil filter cap and filter and allow the oil to drain into the housing. After draining is complete, remove the assembly from the housing.
  4. Remove the filter element by pressing and twisting the side and detaching it from the cap.
  5. Remove the oil filter O-ring and discard. Lightly coat a new O-ring with clean engine oil and install it on the filter cap.
  6. Check the filter housing for any debris and remove if necessary.
  7. Insert a new filter element into the oil filter cap.
  8. Insert the filter element and cap assembly into the housing. Torque the cap to 40 to 50 N·m (30 to 37 lb·ft).
  9. Drain oil from the oil pan. Place a suitable receptacle, 19 L (20 qt) or more, beneath the oil drain plug on the underside of the oil pan.
  10. Carefully unscrew the oil drain plug, and allow the oil to drain out.
  11. Discard the plug seal ring.
    12. Note: There are several variations of plugs and plug locations on the oil pan. The plugs can be either M22 plugs or plastic bottom drain plugs depending on oil pan configuration. The sealing washer for the M22 plug must be replaced once removed. The plastic bottom drain plug must also be replaced once removed. These components are included in the oil filter kit released for service.
  12. Install the oil pan drain plug with a new O-ring and torque the plug.
    • Install the M22 oil pan drain plug, if removed, with a new seal washer and torque the plug to 45 N·m (33 lb·ft) for plastic oil pans and 65 N·m (48 lb·ft) for aluminum oil pans.
    • Install a new plastic oil drain plug, if removed, and torque the plug to 4 N·m (3 lb·ft).
    13. Notice: Do not add oil if the oil reading is between the crosshatch area on the dipstick. There are approximately 4.0 L (4.2 qt) from the fill mark to the full mark. Overfilling the oil pan can cause engine damage.
  13. Add new engine oil through the oil fill tube in the following amount; Engine Oil Capacities. Verify the oil level reading is between the full and fill marks on the dipstick.

    14. 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.
  14. Start the engine with the accelerator pedal in the idle position (600 rpm). Monitor the oil pressure gauge or indicator lamp. Keep the engine running at idling speed (600 rpm) until the oil pressure reading is 345 kPa (50 psi) or more.
    15. Notice: Do not add oil if the oil reading is between the crosshatch area on the dipstick. There are approximately 4.0 L (4.2 qt) from the fill mark to the full mark. Overfilling the oil pan can cause engine damage.
    Note: If the engine operating temperature is below 60°C (140°F), the engine must be on a level surface and then shut down for 60 minutes for an accurate oil level reading. Otherwise, the engine must be brought up to an operating temperature of 60°C (140°F), parked on a level surface and then shut down for 20 minutes for an accurate oil level reading.
  15. Check the filter housing for signs of leakage.
  16. Stop the engine. Check the oil level again per the following guidelines. If necessary, add oil no more than 4.0 L (4.2 qt) at a time up to the maximum fill level on the oil dipstick.
