If your diesel cranks forever, runs rough, or shakes at idle, it could be weak batteries, glow plugs, dirty fuel filters, or injector issues. Our diesel diagnostics will find the real problem and get your truck starting strong again.

Michigan winters are hard on DEF systems. Frozen fluid, bad heaters, or failed NOx sensors can throw warning lights and put your truck into limp mode. We repair DEF tanks, heaters, sensors, and wiring so your truck runs clean without constant shutdowns.

Your Diesel Particulate Filter (DPF) is designed to burn off soot, but when something goes wrong, you’ll see constant regen messages or reduced power. We handle DPF cleaning, manual regens, and repair so you’re not stuck in endless cycles.

Ford, Ram, and older Duramax trucks use fuel pumps that can fail and send metal through the entire fuel system. We inspect for early signs of trouble, replace filters, and perform full diesel fuel system repairs to protect your engine.

Low power, smoke, or whining noises often mean turbo vane problems or boost leaks. We test your turbocharger system, check for leaks, and repair or replace components to restore full pulling power.

From gelled fuel and frozen DEF to dead batteries, Michigan winters bring special challenges for diesel owners. We’ll help you prep your truck with fresh filters, battery checks, and proper diesel maintenance before the cold sets in.

Every diesel truck repair begins with a full inspection so nothing is missed:

• Battery & glow plug system test
   
• Fuel pressure and filter check
   
• High-pressure injector diagnostics
   
• Turbo & boost leak smoke test
   
• DEF/DPF live data analysis
   
• Cooling system inspection
   
• Transmission fluid & temps
   
• Underbody corrosion from road salt
   

This complete diesel diagnostic gives you answers—not guesses.

Want to avoid costly breakdowns? Regular maintenance is the best way to extend the life of your truck:

• Change fuel filters regularly (especially before winter).
   
• Replace batteries in pairs to avoid weak-start issues.
   
• Keep DEF topped up and stored above freezing.
   
• Mix in highway driving to help your DPF system.
   

Bring your truck to us for routine service, and we’ll keep it running smooth year-round.

Whether you drive a Ford Power Stroke, Chevy Duramax, or Ram Cummins, we’ve got the tools, training, and experience to handle all your diesel truck repair needs. Don’t let warning lights, rough running, or winter problems sideline your truck.
