2017 Ram 3500 — Factory Maintenance Schedule

Quick reference

Severe-duty schedule

The 2017 Ram 3500's maintenance schedule can change significantly based on how you use your truck. If you frequently tow heavy loads, operate in dusty or off-road conditions, make many short trips without letting the engine fully warm up, or live in an extremely cold climate, you’ll need to service your truck more often.

For severe-duty users, the oil change interval should be shortened to every 4,000 miles or 400 hours of engine operation, whichever comes first. The on-board oil life monitor will typically indicate this. Additionally, the front and rear axle fluid should be changed every 15,000–20,000 miles, especially if you tow frequently. The transfer case fluid should also be changed more frequently, at approximately 30,000-mile intervals.

Known issues by mileage

• 30,000–60,000 miles: Some owners have reported premature wear on the water pump and radiator, leading to coolant leaks. The factory brake pads and rotors may also require replacement in this window, especially under heavy use.
• 60,000–100,000 miles: The diesel models’ EGR (Exhaust Gas Recirculation) cooler and valve can become clogged, leading to reduced performance and check engine lights. This is more common in trucks that idle frequently or are used for short trips. The front-end components, such as ball joints and tie rod ends, may also show wear, leading to steering looseness.
• 100,000+ miles: High-pressure fuel pump (CP4) failure is a known and costly issue on the 6.7L Cummins diesel engine. When it fails, it can send metal debris throughout the entire fuel system. The automatic transmission can also develop issues with solenoids or the torque converter.

Estimated cost per service

• Basic service (oil change, tire rotation): $100–$200
• Intermediate service (30,000 miles): $400–$700
• Major service (60,000–120,000 miles): $800–$1,500+

What you can DIY vs shop

• DIY: Oil and filter changes, tire rotations, cabin and engine air filter replacements, and accessory belt inspection are all tasks a confident DIYer can tackle.
• Shop: Transmission service, differential and transfer case service, spark plug replacement (especially on the Hemi V8, where some plugs are difficult to access), and any diagnostic work or repairs related to the fuel system or engine internals should be left to a professional technician.
