Preparation

1. Park vehicle on level surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. Allow engine to cool if recently operated
4. Gather all tools, parts, and fluids before beginning
5. Raise front of vehicle with floor jack and secure on jack stands at frame rails
6. Remove engine oil fill cap to allow better drainage

Procedure

1. 1

   Drain engine oil
   Locate the oil drain plug on the passenger side of the oil pan. Position drain pan beneath plug. Remove drain plug and allow oil to fully drain (approximately 10-15 minutes for complete drainage). Inspect drain plug and threads for damage. Replace drain plug washer. Use Mopar 5083285AA / Fleetguard LF16035 or equivalent for 5.9L Cummins (verify against manufacturer documentation).
2. 2

   Replace engine oil filter
   Locate oil filter on driver side of engine block. Position drain pan beneath filter. Use oil filter wrench to remove old filter by turning counterclockwise. Clean filter mounting surface on engine block. Apply thin film of clean oil to new filter gasket. Install new filter hand-tight, then turn an additional 3/4 turn. Do not over-tighten.
3. 3

   Reinstall drain plug and refill engine oil
   Install drain plug with new washer and tighten to 37 ft-lbs (verify against service manual). Using funnel, pour 11 quarts of 15W-40 diesel oil through oil fill opening. Add remaining oil slowly while checking dipstick level. Fill to full mark on dipstick (total capacity approximately 12 quarts with filter — verify against owner's manual). Reinstall oil fill cap.
4. 4

   Replace fuel filter/water separator
   Locate fuel filter/water separator assembly on driver side frame rail near transmission. Place drain pan beneath filter. Turn water-in-fuel (WIF) sensor at bottom of filter housing counterclockwise to drain water and fuel. Disconnect WIF sensor connector. Remove filter housing using oil filter wrench. Install new filter with fresh O-ring, hand-tighten until snug. Reconnect WIF sensor. Prime the fuel system per the factory procedure: cycle the ignition key to 'ON' (without cranking) several times to allow the electric lift pump to fill the filter, or use the hand primer pump if equipped, until firm resistance is felt. Verify procedure against service manual. Use Mopar 68065612AA / Fleetguard FS19765 or equivalent (verify against manufacturer documentation).
   ⚠Diesel fuel will drain from filter. Ensure drain pan is positioned correctly.
5. 5

   Replace engine air filter
   Open hood and locate air filter housing on driver side of engine compartment. Release clamps securing air filter housing cover. Remove cover and extract old air filter. Clean interior of housing with clean cloth. Install new air filter ensuring proper seating. Reinstall housing cover and secure clamps.
6. 6

   Replace cabin air filter
   Locate cabin air filter access panel behind glove box. Remove glove box by squeezing sides to release stop tabs and lowering. Remove cabin air filter access door. Slide old filter out noting airflow direction arrow. Install new filter with airflow arrow pointing toward rear of vehicle. Reinstall access door and glove box.
7. 7

   Lubricate chassis components
   Using grease gun, lubricate any grease fittings present on: front suspension ball joints, tie rod ends, front and rear driveshaft U-joints, and steering linkage. Note: some components are sealed/non-serviceable and will not have fittings. Pump grease until fresh grease appears at boot seal, then wipe excess. Pump grease until slight resistance or until fresh grease appears at boot seal. Wipe excess grease from fittings.
8. 8

   Inspect and top off all fluid levels
   Check and top off as needed: transmission fluid (dipstick on passenger side of transmission, check warm), transfer case (fill plug on passenger side of case), front differential (fill plug on housing), rear differential (fill plug on rear cover or side of housing — locate per service manual), power steering reservoir, brake fluid reservoir, coolant overflow reservoir, and windshield washer reservoir. All levels should be at full mark.
9. 9

   Inspect drive belts and hoses
   Visually inspect serpentine belt for cracks, fraying, or glazing. Check belt tension by pressing midway between pulleys (should deflect no more than 1/2 inch). Inspect all coolant hoses and heater hoses for cracks, soft spots, or leaks. Check hose clamps for tightness. Inspect vacuum lines for damage.
10. 10

    Inspect brake system
    Visually inspect brake pads through wheel spokes or remove wheels for better access. Front pads should have at least 3mm material remaining. Check brake rotors for scoring or excessive wear. Inspect brake lines and hoses for leaks, cracks, or damage. Check caliper slide pins for proper movement.
11. 11

    Rotate and inspect tires
    Inspect tires for uneven wear, cuts, or damage. Check tread depth (minimum 4/32 inch recommended). Rotate tires in appropriate pattern for a 4WD vehicle (rearward cross pattern: rears move straight to front same side, fronts cross to rear). Note: many 3500 duallies should NOT be cross-rotated — follow owner's manual for dual-rear-wheel pattern. Torque lug nuts to 145 ft-lbs in star pattern (verify against owner's manual — dual-rear-wheel specs may differ). Check and adjust tire pressure to specification on door jamb sticker (typically 60-65 psi front, 70-80 psi rear for 3500).
12. 12

    Inspect exhaust system and undercarriage
    While vehicle is raised, inspect entire exhaust system from manifold to tailpipe for leaks, damage, or loose hangers. Check for rust or corrosion on frame and suspension components. Inspect steering components for wear or damage. Check for fluid leaks from engine, transmission, differentials, and transfer case.
13. 13

    Start engine and verify operation
    Lower vehicle from jack stands. Start engine and allow to idle. Monitor for proper oil pressure on gauge (should reach normal range within 10-15 seconds). Check for oil, fuel, or coolant leaks around filter areas and drain plug. Listen for unusual noises. Allow engine to reach operating temperature. Verify engine oil level on dipstick with engine off after run period.
    ℹ️Low oil pressure warning light should extinguish within 10 seconds. If it remains on, shut off engine immediately and check oil level.

Reassembly

1. Ensure all drain plugs, filters, and fill caps are properly installed and tightened
2. Verify no tools or rags have been left in engine compartment
3. Double-check that all fluid levels are correct
4. Confirm all wheels are torqued to specification

Verification

• Check engine oil level on dipstick with engine off - should read full
• Verify no leaks present under vehicle after test drive
• Confirm all warning lights are off on instrument cluster
• Test drive vehicle and verify normal operation of all systems
• Recheck oil level after test drive and top off if necessary
• Reset maintenance reminder light if equipped by following procedure in owner's manual
• Document all findings and service performed, including mileage and date
