2018 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. Engines: see schedule title.

Service20k30k40k50k60k70k80k90k100k110k120k130k140k150k
Additional Inspections
Inspect the CV 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 filter.
Replace the air conditioning filter.
Replace spark plugs.
Flush and replace the engine coolant at 10 years or 150,000 miles (240,000 km) whichever comes first.
Change transfer case fluid.
Inspect and replace PCV valve if necessary.

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 brake pads, shoes, rotors, drums, hoses and park brake.
  • Inspect engine cooling system protection and hoses.
  • Inspect exhaust system.
  • Inspect engine air cleaner if using in dusty or off-road conditions.
