Trailer & Diesel Truck Repair Shop

When your commercial truck is down, you need to have the problem identified and fixed as soon as possible, without delays. Dieseltech Truck Repair & Fleet Maintenance offers a variety of services such as brake and suspension repair, transmission repair, diesel engine repair, electric motor repair, and more to get your truck back on the road.

Worn or damaged suspensions can negatively impact steering, tire wear, load stability, and driver comfort. Our technicians will inspect and repair suspension components such as shock absorbers, control arms, ball joints, and related components. If you experience a rough ride, your truck leans or pulls, or you hear unusual sounds while driving, our technicians will diagnose and fix the problem.

A dependable HVAC system ensures the driver's comfort, clears the windshield, and protects temperature-sensitive cargo. Our technicians will diagnose and repair problems associated with heating, ventilation, and air conditioning systems, including weak airflow, refrigerant leaks, faulty compressors, blower motors, thermostats, and electrical controls.

Problems with drivelines can lead to vibrations, clunking, poor shifting, power loss, and unexpected downtime. At our trailer and truck repair shop, we offer diagnostics, maintenance, repairs, and replacement of components such as transmissions, driveshafts, U-joints, differentials, axles, seals, and bearings. Once repaired, your truck can once again run smoothly and dependably.

Electrical failures can leave a truck unable to start or create intermittent problems that are often difficult to trace. Our technicians use advanced diagnostics to locate problems in wiring, batteries, starters, alternators, lighting, sensors, charging systems, and accessories. Our goal is to identify the root cause of the failure and avoid repeated downtime.

Reliable braking systems are critical for driver safety, vehicle compliance, and dependable stopping performance. We inspect and repair brake systems, including air, hydraulic, disc, and drum brake systems. This includes repairing and replacing pads, shoes, rotors, callipers, chambers, valves, airlines, and ABS components.

Loss of power, excessive smoke, overheating, fluid leaks, and unusual noises are just a few examples of common problems that indicate a potential issue within a diesel engine. We provide diagnostics, inspections, routine service, component replacements, major repairs, and complete rebuilds to restore reliable performance and reduce future breakdowns.

Misaligned wheels and axles can cause uneven tire wear, increased fuel consumption, steering issues, and premature stress on other components. We service commercial trucks and trailers using professional alignment equipment designed for most makes and models. We measure and correct wheel and axle angles to improve handling, protect components, and help extend tire life.

Preventative maintenance programs can help keep your operation moving while reducing unnecessary downtime caused by unexpected failures. Our fleet program offers scheduled inspections, repair service, and maintenance records management for fleets of 100+ vehicles. In addition, we offer mobile fleet repair services at your job site or roadside location to minimize downtime.

Our truck and trailer shuttle service eliminates the hassle of arranging transportation for repairs. We pick up your vehicle, transport it to our Coquitlam shop where repairs will be completed, and then deliver it back to you in the Lower Mainland region. Our shuttle insurance covers the move, so separate transport insurance is not necessary.

As a licensed designated inspection facility, Dieseltech Truck Repair & Fleet Maintenance is authorized to perform safety and compliance inspections on heavy vehicles over 5,500 kg. Our technicians identify any safety concerns or non-compliance issues and perform required repairs. We also offer pre-purchase inspections to provide you with accurate information about the condition of the vehicle before purchase.
