Diesel Engine Repair in Edmonton

Diagnosis and repair of heavy duty diesel engines in Edmonton, from cold-morning no-starts to power loss and derate.

Most engine calls start with a symptom: a hard start on a cold morning, black or white smoke, a loss of power on a hill, or a check engine light with the truck in derate. The first step is reading the fault codes and checking the obvious causes (fuel supply, air intake, boost leaks) before anything gets taken apart.

Hard starts are most common in winter. Edmonton's January nights average −14.7 °C in the city and −18.1 °C at Edmonton International Airport (Environment Canada 1991–2020 normals). If the truck won't start, say whether it cranks and how long it sat; a weak battery or a wiring fault can look like an engine problem.

Tell the shop which engine the truck has (for example Cummins, Detroit, PACCAR, Volvo or Mack) when you call, so it can confirm it works on that engine. In-frame and out-of-frame overhauls are bigger jobs that some shops do in-house and others send to an engine specialist, so ask if you need one. If the truck is in derate, the cause is often in the emissions system.

Common jobs

• Fault code diagnosis and derate troubleshooting
• Fuel system: injectors, fuel pumps, filters and water in fuel
• Turbochargers and charge air leaks
• Cooling system: radiators, water pumps, hoses and overheating
• Oil leaks and gasket replacement

Have this ready when you call

• Year, make and model of the truck or trailer, and the unit number if it's a fleet unit
• Where the unit is now, and whether it can be driven safely
• Any warning lights or fault codes on the dash
• When the problem started and what it's doing (noise, smoke, power loss, air leak)
• A PO number, if your company uses them
