Truck Engine Repair, Overhaul & Conversion Service in Calgary & Lethbridge, Alberta

Mechanic repairing truck engine at Foothills Group

Your diesel engine is a complex machine and identifying an issue with it may not always be easy.  Once a problem with your engine is found though, it can be even more challenging to repair.  If you think your engine is compromised in any way, come see us at Foothills Group and we will fix it for you. When you bring your heavy-duty diesel truck to Foothills Group, you can trust that our skilled technicians will use our sophisticated diagnostic software to find the cause of your problem and come up with an appropriate repair solution. 

How to identify if your engine needs an overhaul or repair?

An engine overhaul is a major diesel engine repair that involves the full removal, disassembly, inspection and repair of an engine. During the overhaul, all components (bearings, pistons/liners, cylinder head, turbo and injectors) are inspected to ensure they are within the manufacturer's tolerance. Any parts that fall outside of those tolerances are replaced.  During disassembly, the engine is cleaned thoroughly to remove built-up grime and debris. Since your entire engine is being taken apart, it’s much easier for our mechanic to identify problems and replace malfunctioning parts. Once everything has been cleaned and the necessary replacements have been made, the engine will be put back together and set back into the truck.

If you notice any of these problems, it is likely time to bring your heavy-duty truck in to get overhauled or repaired  immediately:

  • Your engine has spun a rod bearing. This is one of the worst failures that can occur inside your diesel engine.
  • Your engine has very low or no oil pressure. A fuel or coolant leak can contaminate the engine oil, which leads to a high oil level in the crankcase.
  • Your engine has dropped a valve. This is an all too common and critical fault of a diesel engine.

Our diesel mechanics are trained to identify the problem and fix any diesel engine. By allowing our team at Foothills Group to troubleshoot your diesel engine, we can help ensure that the proper repair procedures are followed to repair your engine.  Our certified mechanics take into consideration the particular manufacturer specifications for your heavy-duty diesel truck and build our diagnostics from there.
