2020 Ram 1500 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: ERG, EZH, EZL.

Additional Inspections
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.
Inspect transfer case fluid.
Additional Maintenance
Replace cabin air filter.
Replace engine air filter.
If equipped with Stop/Start, replace accessory drive belt with OEM grade Mopar belt.
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.

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

  • Change the 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 the battery and clean and tighten terminals as required.
  • Inspect the CV/Universal joints.
  • Inspect the brake pads, shoes, rotors, drums, and hoses.
  • Inspect the engine cooling system protection and hoses.
  • Inspect the exhaust system.
  • Inspect the engine air cleaner if using in dusty or off-road conditions.
  • Inspect and replace the Evaporative System Fresh Air Filter as necessary, replacement may be more frequent if vehicle is operated in extreme dusty conditions.
