2022 Ram 2500 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: ESB.

Change engine oil.
Additional Inspections
Rotate the tires.
Inspect the CV/Universal joints.
Inspect front suspension, tie rod ends, and replace if necessary.
Inspect the front and rear axle surfaces. If gear oil leakage is suspected, check the fluid level. If using your vehicle for police, taxi, fleet, off-road or frequent trailer towing, change axle fluid.
Inspect the brake linings, replace as necessary.
Adjust parking brake as necessary.
Inspect transfer case fluid.
Additional Maintenance
Replace the cabin air filter.
Replace the engine air cleaner 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.
Inspect the transfer case fluid, change for any of the following: police, taxi, fleet, or frequent trailer towing.
Change the transfer case fluid.
Inspect and replace PCV valve if necessary.
