Ram 2500 Maintenance Schedule
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-11 · confidence: medium
Recommended service intervals for the 2019-2025 (DJ) Ram 2500 (6.4L HEMI V8 gas (primary) or 6.7L Cummins turbo-diesel; 5W-20 synthetic (gas); TorqueFlite/68RFE auto).
In short: the 2019-2025 (DJ) Ram 2500 needs an oil change ~6,000 mi / 6 mo via oil-life monitor; do not exceed 8,000 mi / 12 mo / 350 hr. severe/towing ~4,000-5,000 mi, tire rotation ~every 6,000-8,000 mi (each oil service), and has a timing chain (no scheduled replacement). Full service schedule below.
| Oil change | ~6,000 mi / 6 mo via oil-life monitor; do not exceed 8,000 mi / 12 mo / 350 hr. Severe/towing ~4,000-5,000 mi |
|---|---|
| Tire rotation | ~Every 6,000-8,000 mi (each oil service) |
| Brake fluid | Inspect each service; replace if degraded (~every 2-3 yr) |
| Engine air filter | ~15,000-30,000 mi (dust/off-road ~12,000 mi) |
| Cabin air filter | ~12,000-19,000 mi |
| Transmission fluid | Auto: ~60,000 mi normal; ~30,000 mi heavy towing/severe |
| Coolant / antifreeze | OAT coolant ~10 yr / 150,000 mi, then shorter cycle |
| Spark plugs | Iridium, 16 plugs (2/cyl): ~96,000-100,000 mi |
| Timing belt / chain | Timing CHAIN — no scheduled replacement |
Major milestones: ~30k air filter; ~60k trans (severe); ~96-100k plugs; 150k coolant.
Ram 2500 note: The 6.4L HEMI gas V8 is the primary engine; the 6.7L Cummins turbo-diesel runs different intervals — longer monitor-managed oil changes plus its own fuel/water separator and diesel fuel filters (~every 15,000-20,000 mi). These are work trucks: towing and severe duty shorten oil, transmission and coolant intervals sharply, so log service against your actual duty cycle, not just the odometer.
Ram 2500 maintenance FAQ
How often does the Ram 2500 need an oil change?
~6,000 mi / 6 mo via oil-life monitor; do not exceed 8,000 mi / 12 mo / 350 hr. Severe/towing ~4,000-5,000 mi — for the 2019-2025 (DJ) Ram 2500. Use the severe-service interval if you mostly drive short trips, tow, or sit in traffic.
Does the Ram 2500 have a timing belt or a timing chain?
Timing CHAIN — no scheduled replacement.
What are the major service milestones for the Ram 2500?
~30k air filter; ~60k trans (severe); ~96-100k plugs; 150k coolant.

Universal maintenance facts
- Full-synthetic oil typically lasts 7,500-10,000 mi / 12 mo, but turbo and direct-injection engines do better at 5,000-7,500 mi — synthetic resists thermal breakdown longer; turbos run hotter and DI engines suffer fuel dilution, so shorter intervals protect them.
- Rotate tires every 5,000-7,500 mi — front and rear tires wear at different rates; rotation evens wear, extends tire life, and is essential on AWD to avoid drivetrain strain.
- Replace brake fluid every 2-3 years regardless of mileage — brake fluid is hygroscopic — it absorbs water, which lowers its boiling point and corrodes ABS/brake parts, hurting braking when hot or wet.
- Follow the SEVERE schedule if you drive short trips, in cold/dusty/hot climates, in stop-and-go, or tow — those conditions are physically harder on oil, fluids and filters than highway cruising — and they describe most real drivers.
- Most cars since ~2010 use a timing CHAIN (no scheduled replacement); timing BELTS (replace ~60,000-105,000 mi) survive mainly on some VW/Audi and older engines — a snapped belt on an interference engine destroys the engine, so on belt cars the interval is non-negotiable — but most modern owners don't have a belt at all.
- Don't trust 'lifetime' transmission/CVT fluid — change it proactively (CVT ~30,000-60,000 mi, conventional auto ~60,000-100,000 mi) — transmission fluid degrades with heat; 'lifetime' often means the life of the warranty, and a fluid change is far cheaper than a transmission.
- Engine coolant is long-life (often first change ~100,000-150,000 mi), then repeats on a SHORTER cycle — long-life coolants protect ~10 yr first, but the corrosion inhibitors deplete, so later intervals are much shorter and easy to forget.
- Replace the cabin air filter ~every 15,000-30,000 mi or yearly, and the engine air filter ~every 30,000 mi — a clogged engine filter hurts airflow/economy; a clogged cabin filter weakens A/C/heat airflow and lets allergens in — both are cheap, high-satisfaction services.
