2020 Ram 2500 — Factory Maintenance Schedule

Quick Reference: 2020 Ram 2500 Maintenance Schedule

This schedule is a general guide. Your truck's onboard oil life monitor (OLM) may recommend service sooner based on driving habits. Always consult your owner's manual for the most precise information.

Severe-Duty Schedule

The factory defines "severe duty" as operating your truck under one or more of these conditions:

• Towing or hauling heavy loads frequently
• Extensive idling or short trips (under 10 minutes)
• Driving in dusty, sandy, or off-road conditions
• Operating in extreme cold or hot climates

If this describes your usage, you must follow a more aggressive maintenance plan:

• Engine Oil & Filter: Follow the oil life monitor, but expect changes as frequently as every 4,000–5,000 miles, especially on diesel models. Do not exceed 500 hours of engine run time.
• Fuel Filters (Diesel): Change every 15,000 miles or if a "Fuel Filter Service Required" message appears.
• Transmission & Driveline: Consider servicing the transmission, transfer case, and differentials every 30,000–45,000 miles. Heat is the #1 enemy of transmission fluid, and towing generates a lot of it.
• Air Filters: Inspect the engine and cabin air filters at every oil change, replacing them when visibly dirty, which could be as often as every 15,000 miles.

Known Issues by Mileage

The 2019+ Ram HD generation is robust, but some common issues have emerged:

• 15,000-30,000 miles: Some owners report infotainment screen "delamination," where the screen protector layer bubbles. This is often a cosmetic warranty repair. The 68RFE transmission may exhibit harsh 4-5 shifts, which can sometimes be addressed with a software update from the dealer.
• 60,000-80,000 miles: Water pump failures on the 6.4L HEMI are not uncommon around this mileage. Look for coolant drips from the front of the engine. On diesel models, this is the mileage where issues with the emissions system (DEF/SCR) can begin to surface, sometimes requiring sensor replacements.
• 100,000+ miles: The 6.4L HEMI can experience "lifter tick," caused by a failed roller on the camshaft lifter. Using high-quality synthetic oil and avoiding excessive idling can help mitigate this. On all models, electronic modules and sensors can become problematic at higher mileage.

Estimated Cost Per Service

Prices vary by region and dealer vs. independent shop rates.

• Basic Service (Oil Change, Tire Rotation): $100 - $250 (Diesel is more expensive due to oil capacity and filter cost).
• 30,000-Mile Service: $400 - $750. The fuel and air filter replacements are the primary cost drivers, especially for the diesel's two-filter system.
• 60,000-Mile Service: $700 - $1,200+. The transmission and transfer case service are labor-intensive and require specific, costly fluids.
• 100,000-Mile Service (HEMI): $600 - $1,000. The spark plug replacement and coolant flush add significant cost.
• 150,000-Mile Service: Can range from $500 to over $1,500 if belt replacements and other inspections reveal needed repairs.

What You Can DIY vs. Shop

• DIY-Friendly:

  • Engine & Cabin Air Filters: Easily accessible, requiring no special tools. This can save you $100+ in labor.
  • Engine Oil & Filter Change: Straightforward for those with basic tools, ramps, and a large enough drain pan (especially for the diesel's 12-quart capacity).
  • Tire Rotation: Possible with a good jack and jack stands, but often included for free with an oil change at a shop.

• Leave to the Professionals:

  • Fuel Filter Replacement (Diesel): While possible, it can be messy and requires priming the fuel system correctly to avoid airlocks. An error here can leave you stranded.
  • Transmission & Driveline Services: These require special tools to check fluid levels (many transmissions lack a dipstick) and use specific, expensive fluids. Over- or under-filling can cause serious damage.
  • Coolant Flush & Spark Plugs (HEMI): The coolant system must be properly bled to avoid air pockets. The rear spark plugs on the HEMI are difficult to access.
  • Timing Chain Inspection: This is a major undertaking that requires significant disassembly of the engine front.
