When it comes to keeping your Chevy Silverado 2500 with a 6.6L Duramax diesel engine running strong, regular maintenance is the key. Whether you’re towing heavy loads through Southern California or commuting around Temecula, your diesel truck deserves expert care. At American Diesel Truck Repair, we specialize in Duramax diesel maintenance and repair services to help your truck perform at its best—mile after mile.

1. Stay on Top of Oil and Filter Changes

The Duramax 6.6L engine works hard, and clean oil is critical to protect your turbocharger, fuel injectors, and internal components. In Temecula’s warm climate, oil can break down faster, especially under heavy towing or off-road conditions. We recommend oil and filter changes every 5,000 to 7,000 miles for optimal performance.

2. Replace Fuel Filters Regularly

Diesel fuel can easily collect moisture and debris, which may damage your injectors if filters aren’t changed on schedule. Our technicians at American Diesel Truck Repair replace fuel filters every 10,000 to 15,000 miles to ensure smooth fuel delivery and prevent costly injector issues.

3. Check the Cooling System

Southern California heat is no joke, and overheating can quickly turn a good day into an expensive repair. Have your coolant, radiator, and hoses inspected before summer hits. We also flush and refill cooling systems to help prevent corrosion and maintain ideal engine temperatures.

4. Maintain the DEF and Emissions Systems

Newer Duramax engines use Diesel Exhaust Fluid (DEF) and advanced emissions systems to meet California standards. Keeping these components clean and properly serviced helps your truck stay efficient and compliant. Our team can inspect and service your EGR, DPF, and DEF systems to ensure everything’s working right.

5. Inspect Belts, Hoses, and Batteries

Long drives or hauling in the Temecula Valley can put extra strain on your truck’s components. We check belts for cracks, test batteries for charge, and ensure all connections are tight and corrosion-free. Preventive care like this helps avoid roadside breakdowns and lost work time.
