Seasonal hauling puts real strain on your truck, even when nothing seems wrong.

After a heavy-hauling stretch, an overall check-over is the best way to catch small issues before they lead to a breakdown.

We start with a full diagnostic scan, add a visual inspection, and review your gauge and monitor readings, so you know exactly where your truck stands heading into winter. We service diesel and gas vehicles, so whatever you drive, we can take a look!

Contact us to book your check-over: https://supremediesel.ca/contact/

Hearing a strange clunk, hiss, or squeal from your vehicle? Don't ignore it!

Our diagnostic tools quickly find the source, whether it's the brakes, steering, or drivetrain, so you can get back to driving with confidence before winter roads make it worse.

Slick roads test your brakes, steering and suspension all at once. Before the first icy commute, have all three checked.

Pulling to one side, a soft brake pedal, or clunking over bumps are worth looking at early, and we handle brake, steering and suspension work for diesel trucks and everyday vehicles. A quick inspection now helps you catch worn parts before they become a problem on slick roads.

Whether you drive a diesel truck or a daily commuter, it is worth knowing where things stand before the snow flies.

A block heater that hasn't been tested is a gamble on the first hard freeze. A functional block heater helps your diesel engine start quickly and reduces wear once temperatures really drop.

Test it now, before you actually need it, and if it needs a repair or replacement, our team can handle it quickly.

Cooler fall mornings are here, and a weak heater or slow-clearing windshield is more than just uncomfortable; it's a visibility issue.

Get ahead of the freeze! As Northern Alberta temperatures drop, moisture and fuel waxing can quietly build up in your fuel system, leading to hard starts and reduced performance once the cold really sets in.

A pre-winter fuel system check now catches these issues before they cost you a morning on the side of the road.
