Quick reference
| Mileage | Service | Notes |
|---|---|---|
| 5,000 mi | Tire rotation; inspect brakes/fluids/steering/suspension | Rotate dually/SRW in correct pattern; adjust tire pressures to door placard. |
| 5,000–8,000 mi (gas) | Engine oil & filter (OLM) | 5.7L/6.4L HEMI typically 8,000–10,000 mi or when Oil Life Monitor (OLM) prompts; severe duty 5,000–6,000 mi. Use spec oil (5W-20 for 5.7L, 0W-40 for 6.4L; verify in owner’s manual). |
| up to 15,000 mi (diesel) | Engine oil & filter (OLM) | 6.7L Cummins up to 15,000 mi under normal duty with OLM; severe duty 7,500 mi or 6 months. Use CJ-4/CK-4 15W-40 or 5W-40 as ambient temps dictate. |
| 10,000–12,000 mi | Engine air filter inspect | Replace sooner in dusty use. Typical replacement ~30,000 mi; sooner if restriction gauge indicates. |
| 15,000 mi (diesel) | Fuel filter replacement | Cummins fuel filter typically every 15,000 mi or 12 months; severe duty 7,500 mi. Prime/bleed per service procedure. Gas engines: in-tank filter, no routine service. |
| 20,000–30,000 mi | Brake inspection; lube slides | Replace pads/rotors as needed; more frequent checks if towing/hauling. |
| 30,000 mi | Engine air filter (replace if not yet done) | Shorter interval if off-road/dusty. |
| 30,000 mi (gas 5.7L) | Spark plugs (16) | 5.7L HEMI typically 30,000–32,000 mi interval (copper plugs). Use OEM-spec heat range and torque. |
| 30,000–60,000 mi | PCV valve inspect/clean | Gas engines only; replace if sticking or after 100,000 mi. |
| 30,000–60,000 mi (Aisin/68RFE severe) | Automatic transmission service (severe) | Severe duty: change ATF+4 and filters at ~60,000 mi; some fleets service spin-on/filters as early as 30,000 mi. Normal duty often 120,000 mi—verify by transmission (68RFE vs Aisin AS69RC) and owner’s manual. |
| 30,000–60,000 mi (4x4 severe) | Transfer case & differentials service (severe) | Heavy towing/off-road: change fluids around 30,000–60,000 mi. Normal duty often 120,000 mi; confirm axle spec and limited-slip additive requirement. |
| 45,000–60,000 mi | Brake fluid flush | FCA guidance varies; typical best practice 2–3 years (~30k–45k mi). Check owner’s manual; moisture test if unsure. |
| 60,000 mi | Accessory drive belt inspect | Replace at first sign of cracking/glazing/noise. Many belts last to ~100,000 mi. |
| 60,000–100,000 mi | Coolant exchange (OAT) | Ram OAT coolant typically 10 yrs/150,000 mi initial service; some shops test and may service earlier at 100,000 mi. Verify label (OAT vs HOAT) and follow manual. |
| 60,000–120,000 mi (auto, normal) | Automatic transmission service (normal) | 68RFE/AS69RC commonly serviced around 120,000 mi under normal duty. Always confirm by transmission model in the owner’s manual. |
| 75,000–90,000 mi | Front axle U-joints/ball joints inspect | HD duty can wear these; check for play/noise/vibration. |
| 100,000 mi (gas 6.4L) | Spark plugs (16) | 6.4L HEMI typically 100,000 mi iridium/platinum plugs. 5.7L may be on its 3rd set by now. |
| 100,000 mi | Accessory drive belt (replace if original) | Proactive replacement prevents roadside failures. |
| 100,000–120,000 mi | Differential service (normal) | Change gear oil; add friction modifier if equipped with TracRite limited-slip. |
| 120,000 mi (auto, normal) | Transmission fluid & filters | 68RFE/AS69RC fluid and both filters. Follow fill/learn procedures; use ATF+4 and OEM filters. |
| 150,000 mi or 10 years | Coolant exchange (OAT) | First coolant service if not done earlier; replace cap if weak. |
| N/A | Timing belt/chain | No timing belt on 2014 Ram 3500. Hemis use timing chains; Cummins uses gear drive. Inspect only if noisy/leaking front cover. |
| N/A | Cabin air filter | Most 2014 Ram 3500 trucks were not equipped with a factory cabin filter. Retrofit kits exist; otherwise no scheduled replacement. |
Notes: Always follow the Oil Life Monitor (OLM) and the exact intervals in your owner’s manual for your engine/transmission/axle build.
Severe-duty schedule
Severe service includes frequent towing/hauling, commercial idling, dusty or off-road use, repeated short trips, very cold climates, or extensive mountain driving.
- Engine oil: Gas 5,000–6,000 mi; Diesel 7,500 mi or 6 months.
- Fuel filter (diesel): 7,500–10,000 mi.
- Air filter: Inspect every 5,000–10,000 mi; replace as needed (often 15,000–20,000 mi in dust).
- Transmission: 60,000 mi for fluid and filters (Aisin/68RFE); some fleets service spin-on filter earlier—consult manual.
- Differentials/transfer case: 30,000–60,000 mi depending on towing load and water crossings.
- Brakes: Inspect each rotation; fluid flush every 2–3 years.
Known issues by mileage (2013–2018 Ram HD generation)
- 0–30k: Steering and suspension settling; occasional alignment drift after towing heavy. Early brake pad glazing in stop-and-go use.
- 30–60k: HVAC blend door actuators can click/fail. 5.7L HEMI spark plug misfire if 30k interval missed. Front axle U-joint boots cracking in salted regions.
- 50–100k: 68RFE shift flare/harsh 2–3 or P0871 pressure switch codes—often improved by fluid/filter service and valve body diagnostics. Cummins DEF/SCR components (DEF heater, NOx sensors) may fail; watch for CEL/limp mode. Wheel speed sensors and hub bearings can get noisy under heavy loads.
- 60–120k: HEMI “tick” (lifter/cam wear) reported on some 5.7/6.4 engines—use correct oil grade and change on time; investigate persistent tick. Exhaust manifold bolts (HEMI and Cummins) may break, causing ticking and warm-up exhaust leak. Front track bar bushings/ball joints wear—contributes to shimmy; follow torque specs and use updated hardware when applicable.
- 100k+: Water pumps and thermostats (gas) age out. Cummins turbo actuator on VGT can stick; proper battery/charging health and coolant maintenance help longevity. Driveline U-joints and carrier bearings can develop vibration under load.
These are patterns seen in the field; always diagnose before replacing parts and check TSBs/recalls for your VIN.
Estimated cost per service
- Oil & filter: Gas $75–$145; Diesel $140–$250 (12 qts, premium filter).
- Fuel filter (diesel): $150–$300.
- Engine air filter: $35–$85.
- Spark plugs: 5.7L (16 plugs) $250–$450; 6.4L (16 long-life) $350–$600.
- Transmission service (68RFE/AS69RC): $350–$650 (pan, fluid, both filters); Aisin typically higher.
- Transfer case service: $110–$200.
- Differential service (each axle): $140–$250; add $15–$25 for limited-slip additive if required.
- Brake fluid flush: $120–$180.
- Coolant exchange (OAT): $180–$300.
- Accessory belt: $120–$220 parts/labor; add if idlers/tensioner needed.
Prices vary by region, fluid spec, and parts quality.
What you can DIY vs shop
DIY-friendly
- Engine oil & filter, tire rotations (with proper torque sequence on dual rear wheels), engine air filter.
- Diesel fuel filter (if you have the priming procedure and proper drain pan).
- Cabin filter retrofit (if desired) and replacement thereafter.
- Differential and transfer case fluids if you have hand pumps and torque specs.
Best left to a shop
- Automatic transmission service (correct ATF+4 fill procedure, filter seating, relearn/updates).
- Brake fluid flush with electronic ABS cycling where required.
- Spark plugs on HEMIs (16 plugs; tight access, correct torque/anti-seize guidance varies by plug type).
- Front-end work (ball joints/track bar) requiring press tools and precise torque/angle specs.
- Cooling system exchange and bleed on Cummins to avoid air pockets; turbo actuator diagnostics.
Engine/trans/axle specifics matter on the 2014 Ram 3500. When uncertain, follow the typical ranges above and confirm exact intervals in your owner’s manual based on your VIN build (engine: 5.7L/6.4L HEMI or 6.7L Cummins; transmission: 68RFE, AS69RC Aisin, or manual; axle ratios and limited-slip).
