Understanding Light-Duty Diesel Repairs, Truck by Truck
Light-duty diesel trucks are the backbone of Colorado’s trades, farms, and fleet operations. These hardworking vehicles, ranging from ½-ton to 1-ton pickups, are built to handle heavy loads, rugged terrain, and high-mileage demands, all while delivering long-term reliability and fuel efficiency.
Here’s how these trucks are commonly classified:
- ½-Ton Trucks – Ford F-150 Diesel, Ram 1500, Chevy 1500 Diesel
- ¾-Ton Trucks – Ford F-250, Chevy 2500 HD, Ram 2500
- 1-Ton Trucks – Ford F-350, Chevy 3500 HD, Ram 3500
- Up to 2-Ton Workhorses – Select outfitted pickups or flatbed trucks within Class 3 weight limits
Common Issues in Light-Duty Diesel Trucks
Light-duty diesel engines are built tough, but they come with their own set of challenges. Our experienced technicians are trained to spot and solve these diesel-specific issues quickly and accurately, including:
Diesel-Specific Problems
- Injector Failures: Cause hard starts, rough idle, and poor fuel economy.
- Turbocharger Issues: Power loss, smoke, or squealing often means turbo trouble.
- Fuel Contamination: Water or debris can damage pumps and injectors.
- Glow Plug Failures: Lead to hard starts, especially in cold weather.
- DPF Clogs: Hurt fuel efficiency and engine performance.
Truck Wear & Tear
- Suspension & Steering Wear: Heavy loads strain key components.
- Brake Stress: Diesel trucks need stronger, more frequent brake service.
- Electrical Glitches: Bad sensors or wiring cause misfires and warning lights.
- Transmission Strain: Towing without proper service leads to early wear.
