No-start & electrical diagnosis
Batteries, alternators, starters, grounds and parasitic draws traced with a load tester and a proper scan tool — not guesswork and parts-swapping. Most no-starts are a diagnosis problem before they're a parts problem.

What we do
Roadside and yard-side repair, done properly
Air brake service & inspection
Slack adjusters, chambers, valves, lines and compressor work on air-braked tractors and trailers. We can get you back to a legal, roadworthy brake system and document what was done for your CVOR file.
Roadside tire changes
Steer, drive and trailer tires changed on the shoulder or in your lot, torqued to spec. We carry the common sizes for highway tractors and can source odd sizes the same day.
Cooling systems & overheating
Hoses, water pumps, thermostats, radiators, EGR coolers and pressure testing. Overheating on a diesel is expensive if you keep driving — call before the head gasket decides for you.
Fuel & aftertreatment faults
Fuel filters, lift pumps, injector faults, DEF and DPF derate issues. If your dash is counting down to a shutdown, that's the call to make first.
Preventive maintenance on site
Oil and filter services, greasing, fluid top-ups and DOT-style walk-around inspections done in your yard overnight so the truck is earning again by morning.
Trailer & landing gear repair
Lights, wiring, gladhands, mud flaps, doors, hinges and landing gear legs. Small failures that take a trailer out of service are usually a short visit.
Fleet accounts & scheduled call-outs
Running more than a couple of units? We'll set up a standing arrangement for after-hours service so your drivers have one number to call and you get one invoice.
How a call-out works
One phone call, then we're moving
-
01
Call and describe it
Tell us the unit — tractor, trailer, box truck — and what it's doing. A no-start, a derate, an air leak, a flat. If you have the plate or unit number handy, even better.
-
02
Tell us where it's sitting
Exact address, cross street, or the highway and direction. If it's on a shoulder, tell us which side and whether you're behind a barrier — that changes how we approach it safely.
-
03
We load the right parts
Because we know the fault and the unit before we leave, the van goes out with the likely parts on board instead of making a second trip to a supplier.
-
04
Repair on site, or a straight answer
Most calls are fixed where the truck sits. If it genuinely needs a shop, you'll get a plain answer about why rather than a tow you didn't need.
Who you're calling
An independent mechanic, not a call centre
Andrew Mobile Truck Repair has been working out of Scarborough for years, servicing the tractors, trailers and delivery trucks that keep the eastern GTA moving. The business runs the way a lot of good trades businesses run: one number, one mechanic who knows the truck, and a straight answer about what it needs.
That matters more than it sounds. A truck sitting at a dock in Markham or dead on the shoulder near the 401 is losing money by the hour. The difference between a mobile mechanic and a tow to a dealership is usually the difference between a repair today and a repair next week — plus the tow bill on top.
The van carries the tools and the common parts for highway tractors and light commercial units, and the work is documented so you know exactly what was replaced and why. If you run a small fleet, ask about a standing account so your drivers aren't hunting for a number at 2 a.m.

What drivers say after the call
"Called at eleven at night with a trailer that wouldn't build air. He was there inside the hour and had us rolling before the yard opened."
Owner-operator, tractor-trailer
"Diagnosed a no-start our own guy had been chasing for two days. Turned out to be a ground strap. Fair price, no drama."
Fleet supervisor, Scarborough
"Straight with me about what was worth fixing and what wasn't. That's rarer than it should be."
Box truck owner, Markham

Shop & base
Andrew Mobile Truck Repair (On Call)426 Nugget Ave
