2021 Dodge Durango maintenance schedule

The factory schedule for normal driving. Oil changes follow the oil-change indicator on most models; severe use (towing, dusty roads, lots of idling) shortens some intervals.

A dot means the service is due at that mileage or after that many years, whichever comes first. Engines: see schedule title.

Additional Inspections
Inspect the CV/Universal joints.
Inspect front suspension, tie rod ends, and replace if necessary.
Inspect the front and rear axle fluid, change if using your vehicle for police, taxi, fleet, off-road or frequent trailer towing.
Inspect the brake linings, parking brake function.
Inspect transfer case fluid.
Additional Maintenance
Replace engine air cleaner filter.
Replace the cabin air filter.
Replace spark plugs.The spark plug change interval is mileage based only, yearly intervals do not apply.
Flush and replace the engine coolant at 10 years or 150,000 miles (240,000 km) whichever comes first.
Replace accessory drive belt.
Inspect accessory drive belt tensioner and pulley, replace if necessary.
Change transfer case fluid.
Replace PCV valve.

At Every Oil Change Interval As Indicated By Oil Change Indicator System

  • Change oil and filter.
  • Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
  • Inspect battery and clean and tighten terminals as required.
  • Inspect the CV/Universal joints.
  • Inspect brake pads, shoes, rotors, drums, hoses and parking brake.
  • Inspect engine cooling system protection and hoses.
  • Inspect exhaust system.
  • Inspect engine air cleaner filter if using in dusty or off-road conditions. Replace engine air cleaner filter, if necessary.
