2022 Ram 3500 Factory Maintenance Schedule

Quick reference

Maintaining your 2022 Ram 3500 according to factory specifications is critical for ensuring its longevity, reliability, and resale value. Ram engineering has designed a comprehensive schedule to keep your heavy-duty truck performing optimally, whether you use it for daily driving, hauling, or serious towing.

Normal Duty Schedule Breakdown

The 2022 Ram 3500, with its robust build and powerful engine options (6.4L HEMI V8 or 6.7L Cummins Turbo Diesel), requires diligent adherence to its maintenance schedule. The intervals below are based on normal driving conditions.

Every 5,000 Miles or 6 Months (whichever comes first): Oil & Filter Change, Tire Rotation. This is the most frequent service item. Regular oil and filter changes are vital for lubricating the engine's moving parts, preventing wear, and dissipating heat. Given the heavy-duty nature of the Ram 3500, using the recommended synthetic or synthetic blend oil is a must. Tire rotations ensure even tire wear, extending their lifespan and maintaining optimal handling.

Every 15,000 Miles or 6 Months: Cabin Air Filter, Engine Air Filter. At this interval, in addition to your oil change and tire rotation, inspect your cabin air filter and engine air filter. The cabin air filter keeps the air inside your truck clean and free of dust, pollen, and other allergens. The engine air filter protects your engine from airborne contaminants, ensuring proper air-fuel mixture and preventing premature wear. For 4x4 models, inspecting the front and rear axle fluid level is also recommended.

Every 30,000 Miles or 2 Years: Fuel Filter(s), Brake Fluid Flush, Differential Service, Transfer Case Service (4x4). If your Ram 3500 is equipped with the 6.7L Cummins Turbo Diesel, fuel filter replacement is crucial at this interval. Diesel fuel systems are highly sensitive to contamination. A brake fluid flush replaces old, moisture-laden fluid, which can compromise braking performance and lead to corrosion in the braking system. Differential fluid service ensures proper lubrication of the gears in your axles. For 4x4 models, the transfer case fluid should also be changed to maintain its smooth operation.

Every 60,000 Miles or 2 Years: Transmission Fluid Service, Accessory Drive Belt, Coolant Flush. Transmission fluid service, including a fluid and filter change (if applicable), is essential for the longevity of your heavy-duty transmission, especially if you tow or haul frequently. The accessory drive belt (serpentine belt) should be inspected for wear and replaced if cracking or fraying is present. A coolant flush replaces degraded engine coolant, preventing corrosion, overheating, and maintaining proper engine temperature regulation.

Every 100,000 Miles: Spark Plugs (Gasoline Engines). For Ram 3500 models with the 6.4L HEMI V8, spark plug replacement is recommended at 100,000 miles. This maintains optimal combustion, fuel efficiency, and engine performance. Diesel engines do not use traditional spark plugs; instead, they have glow plugs, which typically have a much longer service life and are generally replaced only when they fail.

Timing Chain: The 2022 Ram 3500, regardless of engine, uses a timing chain, not a belt. Timing chains are designed to last the life of the engine under normal operating conditions and typically do not require regular replacement. However, it
