Diesel Truck Repair
Diesel engine repair, troubleshooting and performance diagnosis.
Diesel engines fail differently than gasoline engines. Fuel delivery, air intake, charge-air pressure, cooling and electronic controls are all tied together, and a single weak component can look like five different problems from the driver's seat.
LS Truck Repair diagnoses diesel drivability complaints — hard starting, low power, rough running, excessive smoke, unexpected shutdowns and fuel or coolant loss — and then repairs the cause. You get told what was found and what it will take to correct it.
