How to Diagnose Your Heavy Truck’s Problems: Our Guide

As the number of Edmonton-based heavy truck drivers grows every year, the city’s industries have seen increased growth levels as more professionals are ready to shuttle the economy back and forth. 

If you’ve been on the lookout for a new meaningful job opening, then you’ve likely taken a liking to maneuvering a truck and staking your claim in one of Canada’s growing sectors. After going through all the exams, practice, and application processes, you’ll definitely be at a point where you’re equipped to take on the open road. 

With a vehicle entrusted to your care, you now have the ever-growing responsibility to ensure that everything is done well to ensure that it runs optimally at every chance it gets. Over time, however, you’ll quickly realize that there is so much more to learn when it comes to caring for your truck and ensuring that it stays in the right shape, more so when it comes to the concept of truck diagnostics. 

A few terms that can help you get started

As it becomes clearer that there are far fewer mechanics than drivers, it is now your responsibility to ensure that all the noises and sensations that spell trouble are acted upon. However, this is often easier said than done if you can’t connect the dots. Thankfully, there are a handful of heavy truck diagnostics terms that will help make sense of what’s going under the hood so that you can act quickly to prevent a worse disaster from happening: 

1. Bucking (a.k.a. “ha-ha-hachoo!” or the “big hesitation” in your engine)

If you feel like your engine hesitates or “lurches” every time you change gears during a long drive, then you’re likely experiencing an episode of bucking.

Generally, what happens during bucking is that the transmission slips more than it should during a gear change, causing a slipping or hesitation (like a sneeze that almost doesn’t come) in the process. When it comes to causes, bucking is usually linked to a lack of adequate fuel supply to the engine that is needed to maintain power, resulting in recognizable hesitation. 

2. Backfiring (a.k.a. “pop-pop-bang” or “bang-pop-pop-crackle”)

Another critical truck diagnostic term that you should get familiar with (and one that is too distinct to ignore) is engine backfiring.

Best defined by its combination of crackles, pops, and alarming gunshot-like sounds, backfiring is an engine issue that always comes out of the tailpipe. Seeing that this problem is caused by unburnt fuel in the exhaust system (which ends up rapidly combusting, resulting in a pop) that leads to power loss, it’s critical to have Mach 6’s experts take care of it immediately. 

3. Knocking (a.k.a. “knock, knock, knock” or “rapid rattle”)

When you accelerate and hear a rapid rattling noise under the hood follow suit, then it’s safe to say that you’re dealing with a knocking problem that needs to be treated right away. 

A prevalent cause of knocking under the hood that can’t ever be overlooked is an uneven fuel burn, which can be linked to various causes that have their set of repercussions when not dealt with properly. If you start experiencing a great deal of rapid rattling under the hood, take this as a sign to schedule a session with our mechanics!
