The 2022 Ram 3500 is a heavy-duty workhorse, designed to tackle the toughest jobs with its impressive towing and hauling capabilities. To keep your Ram 3500 performing at its peak for years to come, adhering to a comprehensive maintenance schedule is crucial. This guide, written by an ASE-certified master technician, will provide a detailed breakdown of factory service intervals, discuss common issues, severe-duty adjustments, typical service costs, and highlight important recall awareness for your 2022 Ram 3500.
Factory Service Intervals
Ram provides specific maintenance recommendations to ensure the longevity and reliability of your 3500. While these are general guidelines, always refer to your owner's manual for the most accurate and detailed information for your specific vehicle configuration (engine, transmission, etc.).
Engine Oil and Filter
For the 6.4L HEMI V8 engine, Ram recommends an oil change every 8,000 miles or 12 months, whichever comes first, using FCA US LLC Material Standard MS-6395 and API Certified SAE 0W-20 engine oil. For models equipped with the 6.7L Cummins Turbo Diesel engine, the interval is typically 15,000 miles or 12 months, though the Electronic Vehicle Information Center (EVIC) will provide a more precise "Oil Change Due" message based on your driving conditions. Always use API CJ-4 or CES 20081 approved engine oil for the Cummins.
Air Filters
Engine Air Filter (6.4L HEMI): Inspect every 20,000 miles or 24 months, replace as needed. More frequent replacement may be necessary in dusty conditions.
Engine Air Filter (6.7L Cummins): Inspect every 15,000 miles or 12 months, replace as needed. The Cummins engine relies heavily on clean air for optimal performance and longevity.
Cabin Air Filter: Replace every 15,000 miles or 12 months, or more often if you frequently drive in dusty or polluted environments.
Fluids
Brake Fluid: Inspect every 20,000 miles or 24 months. Ram recommends replacing the brake fluid every 30,000 miles or 24 months for optimal performance and to prevent moisture contamination.
Coolant: For the 6.4L HEMI, the initial coolant change is at 100,000 miles or 5 years, then every 50,000 miles or 24 months thereafter using OAT (Organic Additive Technology) coolant. For the 6.7L Cummins, the initial fill is often good for 100,000 miles or 5 years, with subsequent changes every 50,000 miles or 24 months using a MOPAR-approved OAT coolant.
Transfer Case Fluid: Inspect every 30,000 miles or 24 months, replace as needed, or every 60,000 miles under normal driving conditions. Use the recommended MOPAR transfer case fluid.
Front and Rear Axle Fluids: Inspect every 30,000 miles or 24 months. Replace every 60,000 miles under normal conditions, or more frequently if towing/hauling heavily. Consult your owner's manual for the specific fluid type and capacity based on your axle configuration.
Automatic Transmission Fluid & Filter: For the 6.4L HEMI with the 8-speed automatic (8HP75), Ram states that fluid and filter changes are not required under normal operating conditions. However, under severe duty (heavy towing, frequent off-road, commercial use), it
