Mobile Diesel Mechanic on the I-94 Corridor

No-start, rough running, a dash full of warning lights, or charging and cooling trouble? Our mobile diesel mechanic diagnoses and repairs at your truck — no tow, 24/7.

Mobile Diesel Mechanic that comes to your truck

A diesel that won't start or won't stay running doesn't automatically mean a shop visit. Most of the engine problems that strand a truck — dead batteries, a failed alternator, a coolant leak, a fuel or filter issue, a sensor throwing the engine into derate — can be diagnosed and repaired right where the truck sits. Our mobile diesel mechanic brings the diagnostic equipment and common parts to you.

We cover mobile diesel mechanic service on semis and heavy trucks across the I-94 corridor within about 100 miles of Alexandria, MN. One call gets you a DOT-certified tech with 15+ years of experience who can read the codes, find the fault, and in most cases have you rolling without a tow bill or a lost day.

Why a mobile diesel mechanic beats a shop visit

A down engine is usually a part plus a diagnosis — not a shop. Towing a loaded combination to a dealer means a tow bill, a service queue, and a driver burning clock in a waiting room, when the actual fix is often a battery, a belt, a sensor, or a filter a mobile diesel mechanic carries on the truck.

If you're broken down on the shoulder right now, just call — we run 24/7. This page covers the engine work itself: finding what's wrong and repairing it on site so the load keeps moving.
