Heavy-Duty Mobile Repair SPecialists

Brake Systems: If your truck's brakes are making more noise than stopping power, it is time for a thorough check-up. We offer an all-encompassing brake repair service, addressing elements ranging from brake shoes to slack adjusters. In the realm of brakes, cutting corners is simply not an option.

EGR and DPF Repair: The Exhaust Gas Recirculation (EGR) and Diesel Particulate Filter (DPF) play key roles in your emission system. If you are blowing black smoke or noticing abysmal fuel economy, it could be a sign that your EGR valve or DPF is crying out for help. We are talking about specialized cleaning and, sometimes, replacements.

Diagnostics: Specializing in JPRO's advanced diagnostic and troubleshooting functions, Ontario Mobile offers services for a wide range of on-road and off-road vehicles and machinery. JPRO presents a comprehensive vehicle overview, neatly organizing essential service data and problem-specific troubleshooting steps in one central. 

Coolant Systems Repair: Radiator leaks, water pump malfunctions, or coolant line issues can make the engine overheat. Let's get those sorted before your truck becomes a steaming roadside attraction.

HVAC Systems Repair: The HVAC system keeps your cabin. Issues with refrigerant leaks or faulty thermostats can become annoying during long days. And we all know the last thing you need is to.

Oil and Fluid Service: Regularly checking and replacing engine oil, gear oil, and other essential fluids can improve your truck's performance.

Tire Repair: Worn treads, punctures, or alignment issues in your tires can make a ride rougher than a cobblestone street. 

Transmission Repair: Transmission issues will lead to grinding gears and slippage in the transmission. A transmission that does not work properly means inefficient truck systems and lower fuel economy. 

Fleet Services: Using DiagnosticLink software, we deliver a finely-tuned computer-assisted diagnostic service, ideal for powertrains and Freightliner vehicle platforms. This comprehensive software presents vital ECU metrics, flags diagnostic error codes, and provides current instrumentation readings. We can also streamline your fleet operations with the PACCAR Davie 4. The PACCAR Davie 4 can test the DPF regenerations and discover hidden problems like miscalibrated ECU.
