Updated October 6, 2026 · Horne Chrysler Dodge Jeep Ram service, Globe, AZ

For reliable Ram Cummins diesel service in Globe, AZ, our team at Horne Chrysler Dodge Jeep Ram is here to help. We know exactly how to take care of your Ram 2500 or 3500 with a Cummins engine, ensuring you get the best performance, especially when towing in Arizona's heat. From fuel filter replacements to cooling system inspections, we've got you covered.

Essential Cummins Diesel Maintenance

Keeping your Ram's 6.7L Cummins diesel engine in good shape requires sticking to the factory-recommended maintenance schedule. In the demanding conditions around Globe—like towing, desert driving, or high-speed travel in hot weather—it's vital to follow severe-service intervals. This helps avoid costly repairs and keeps your truck running smoothly. The Stellantis verified factory maintenance schedule for the 6.7L Cummins lays out the specific services you need to keep your truck in top condition.

Fuel System Maintenance for Your Cummins

The fuel system is one of the most crucial parts of maintaining your Cummins diesel. Clean fuel is essential for the health of your engine’s injectors and fuel pump. According to Stellantis guidelines, both fuel filters on your 6.7L Cummins should be replaced every 15,000 miles. This regular upkeep prevents contaminants from reaching sensitive engine components—especially important given the varying fuel quality and dusty conditions we often see around here.

Diesel Exhaust Fluid (DEF) is also a key player in keeping your engine running smoothly and minimizing emissions. The Stellantis schedule recommends topping up your DEF every 7,500 miles. Keeping your DEF tank filled is crucial for your truck's emission systems to function properly and helps you avoid potential power derates.

Oil Changes and Engine Cooling

Regular oil changes are a must for any engine, including the 6.7L Cummins. The Stellantis maintenance schedule for the Ram HD 6.7L Cummins calls for an oil and filter change every 15,000 miles or 12 months, whichever comes first. Plus, the Oil Change Indicator system will remind you of service within 500 miles of needing an oil change, ensuring you never exceed these limits. When you come in for an oil change, our skilled technicians will also check your battery, CV/U-joints, brakes, cooling system, and exhaust, plus rotate your tires.

In Globe's hot climate, keeping your cooling system in shape is especially important, particularly if you frequently tow. The Stellantis schedule suggests coolant replacement at 10 years or 150,000 miles, but we include regular cooling system inspections with every oil change. This helps catch any issues early, so your engine stays cool, even when you're hauling heavy loads or driving fast in temperatures over 90°F.

Other Important Cummins Services

Beyond fuel and oil, there are other maintenance tasks that are key to the health of your Ram Cummins. The engine air filter is crucial for proper engine breathing. While the normal schedule suggests replacement every 30,000 miles, if you often drive in dusty or off-road conditions, it’s wise to check the engine air filter at each oil change. This proactive step helps keep dirt and debris from entering your engine.

Transmission fluid and filters for the 6.7L Cummins should be replaced at 120,000 miles. If you're using your Ram for heavy-duty work, like frequent trailer towing, you should change axle fluid every 30,000 to 40,000 miles, and transfer case fluid at 60,000 or 120,000 miles, depending on the model and use. These services are essential for the longevity and smooth operation of your truck's drivetrain.
