Diesel & Truck Repair Shops in Fort Collins, CO

12 of the 134 auto repair shops we list in Fort Collins have diesel engine or heavy truck repair.

Diesel engines and heavy trucks need different tools, parts and training than passenger cars, and many shops turn them away. Every shop here names diesel, semi, heavy-duty or commercial truck work in its business name, listing or on its own website — a shop that services “cars, trucks and SUVs” is not enough.

Say what you drive. A shop that works on diesel pickups (Duramax, Power Stroke, Cummins) is not always set up for semi trucks, and fleet shops may put contract customers first. If you run a commercial vehicle, ask whether they do DOT inspections.

Good to know

Do I need a diesel specialist for my pickup?

Most shops can handle routine maintenance, but fuel injection, turbochargers, diesel emissions systems (DPF, DEF, EGR) and engine repairs are best done by a shop that works on diesels every day.

Where can I get a DOT inspection?

Commercial truck shops and some diesel repair shops perform annual DOT inspections with a qualified inspector. Call ahead — not every truck shop offers them.
