Diesel Service & Repair in Hutto, TX.

Yes — we service Ford Power Stroke, GM/Chevrolet Duramax, and RAM Cummins light-duty diesels, including routine maintenance, injector and turbo work, EGR and DPF diagnostics, and emissions-related repairs. We have the diesel-specific scan tools, lift capacity, and oil-handling equipment that these trucks require. If your truck has aftermarket tuning or hardware changes, let us know up front so we can advise honestly on what we can and can't service.

Modern light-duty diesels typically need oil changes every 5,000–7,500 miles depending on driving conditions, with severe-duty intervals tightening that on trucks used for towing, idling, or dusty work environments. Fuel filters generally need replacement every 15,000 miles — and on most Duramax and Power Stroke trucks there are two filters, both of which we replace together. We follow your specific manufacturer's severe-duty schedule because under-servicing a high-pressure common-rail injection system leads to very expensive injector and pump failures.

The Diesel Particulate Filter (DPF) is a ceramic filter in the exhaust that traps soot, then periodically burns it off during a high-temperature "regeneration" cycle. When regen can't keep up — usually because of short-trip driving, a failed EGR cooler, a leaking injector, or a bad differential pressure sensor — the filter clogs and triggers limp mode. We diagnose why regen is failing, repair the upstream cause, and then either complete a forced regeneration or send the filter out for thermal cleaning, depending on how loaded it is.
