Verified Reviews for Diesel Truck Mechanic
★ ★ ★ ★ ★

“They helped me fix my skidsteer drivewheel bearings. They did a great job just took a few days to get an idea of when I will be getting the parts. I couldn't get the price of the repair until it was done. Otherwise a great service and would recommend them. If you have power equipment or heavy vehicles. They are the place to go.”

“I had a great experience at PowerStroke Performance! Moe is a really nice guy and incredibly knowledgeable when it comes to Fords. He did the safety inspection on my 2020 Ford F-150 and made the whole process smooth and easy. You can tell he takes pride in his work and truly knows his stuff. Highly recommend this shop if you want honest, expert service!”

Common Diesel Truck Issues

Contaminated diesel fuel or clogged fuel filters restricting flow
Failing fuel injectors or high-pressure fuel pumps (HPFP) losing rail pressure
Clogged EGR valves and cracked EGR coolers causing overheating and coolant loss
Turbocharger bearing failure, sticking variable-geometry vanes, or boost leaks
Glow plug or intake heater malfunctions preventing cold-weather starting
Diesel Particulate Filter (DPF) clogging from excessive idling or short trips

When to Book a Diesel Mechanic

Hard starting or extended cranking, especially in cold weather
Excessive black smoke (rich running), white smoke (coolant leak), or blue smoke (oil burning) from the exhaust
Distinct metallic "knocking" or "clatter" sound indicating injector or bearing failure
Check Engine light, Water in Fuel warning, or emission system derate mode
Significantly reduced towing power, turbo lag, or sluggish acceleration
Frequent forced DPF regeneration cycles or "Exhaust Filter Full" warnings on the dash

Diesel Truck Mechanic Tips

Always purchase diesel fuel from high-volume, reputable stations to minimize contamination risk
Drain the water separator at every oil change and immediately if the Water in Fuel light illuminates
Use a high-quality winter anti-gel additive when temperatures consistently drop below -15°C
Avoid excessive idling—it prevents the DPF from reaching regeneration temperature and causes clogging
Let the turbo cool down by idling for 30-60 seconds before shutting off the engine after heavy towing
Follow the severe-duty oil change interval if you tow, haul, or drive in extreme temperatures regularly

Frequently Asked Questions

Are diesel truck repairs more expensive than gas engine repairs in Burlington? +
Generally, yes. Diesel engines operate at much higher pressures and tolerances than gasoline engines. Components like fuel injectors ($300-$600 each), high-pressure fuel pumps ($1,500-$3,000), and turbochargers ($1,500-$3,500) are significantly more expensive. Diesel-specific diagnostic tools and specialized labor also contribute to higher repair costs.
How much does a diesel fuel injector replacement cost in Burlington? +
A single diesel injector replacement costs $500-$1,000 including parts and labor. Replacing all injectors on a common 6-cylinder diesel (Cummins 6.7L, Duramax 6.6L, or Power Stroke 6.7L) typically runs $3,000-$6,000+. It's often recommended to replace all injectors at once to avoid repeat labor costs.
What does it mean when my diesel truck goes into derate or limp mode? +
Derate mode is the engine's ECM intentionally reducing power to protect itself from further damage, usually triggered by emission system faults (DPF, DEF, EGR), overheating, or low oil pressure. You should drive only to the nearest safe repair facility at reduced speed. Ignoring derate can lead to a complete engine shutdown.
How often should I service my diesel truck's DPF system? +
Most diesel DPF systems require a professional cleaning (ash removal) every 150,000-300,000 km, depending on driving conditions. Trucks driven primarily in city stop-and-go traffic or at idle may need it sooner. A DPF cleaning costs $300-$600 and is far cheaper than a replacement filter ($2,000-$5,000+).
