Truck Repair & Maintenance Services

Brake Repair

Brake systems are a critical component of any light, medium, and heavy-duty truck and trailer. Brake systems that are not operating properly make it more challenging to slow down, take turns, and stop, putting the driver and other vehicles in danger.

DOT Inspections

Every commercial vehicle over 10,001 lb operating in the United States, or vehicles transporting hazardous materials regardless of weight, requires, at the minimum, an annual DOT inspection.

Diagnostics & Electrical Repair

At JE-CO Truck & Trailer, we specialize in finding solutions for complex, hard-to-diagnose problems. Your vehicle has several systems to alert you to issues, but there are a few warning signs that you should look for, and if found, address immediately:

Driveline Repair

We offer expert driveline system maintenance and repair services for light, medium, and heavy-duty diesel trucks that can save you from problems down the road.

EGR/DPF Cleaning & Repair

Most diesel vehicles often experience issues in their exhaust gas recirculation (EGR) and diesel particulate filter (DPF) system.

Electrical Repair

From starter service to alternator repairs to complex electrical issues, our ASE certified and DOT licensed electrical technicians are heavy-duty experts for your CAT, Cummins, International, Detroit Diesel, Hino, or Paccar engine.

Engine Conversions

Performing a diesel-engine swap isn’t easy. It takes time, knowledge, and patience. That's why we start every project with a conversation.

Exhaust & Aftertreatment

Exhaust and aftertreatment issues can lead to decreased power, acceleration, fuel economy and cause unanticipated downtime for your truck.

HVAC Systems Repair

Whether you're in the middle of a hot summer and in desperate need of air conditioning repair or bracing for a cold winter and need to ensure your heating system is performing properly, cabin comfort is one of the most important aspects for a driver.
