Signs Your Diesel Truck Needs Repairs

When it comes to diesel vehicles, prevention is often the best cure. Some types of car trouble announce themselves with early symptoms. Seeing a repair professional right away can minimize the damage and keep repair costs down. Addressing the following red flags immediately is a good way to keep your automobile in great working condition:

  • Engine oil inside the cooling system
  • Overheating
  • Exhaust system generating white smoke
  • Poor running with cold engine
  • Engine oil is 15°F above coolant temps
  • Coolant leakage
  • Hard starts
  • General loss of performance
  • Increased fuel usage


  • Transmission and Clutch – We offer scheduled inspections and servicing of your transmission to help your transmission work at its absolute best for a longer period of time. Additionally, we offer a full range of repair services, including overhauls and replacements.
