Diesel Engine Repair in Apex, NC

Diesel Services at GMP Automotive Inc.

At GMP Automotive Inc., we proudly cater to diesel trucks and jeeps from manufacturers such as GM, Chevy, Dodge, Ford, and more. Our specialization extends to the maintenance of diesel engines, with a focus on Duramax, Power Stroke, and Cummins.


Cooling and Lubrication Systems
To prevent costly diesel engine repairs in the future, it's essential to maintain your diesel engine's cooling system effectively. Ensuring efficient cooling and lubrication in high-performance Duramax, Power Stroke, and Cummins diesel engines is the key to extending the lifespan of vital components such as glow plugs, injectors, and turbos.

Glow Plug Replacement
In all weather conditions and road scenarios, your truck or jeep relies on its glow plug to generate the necessary heat and electrical resistance for engine ignition. We offer the ideal glow plug options for Duramax, Power Stroke, and Cummins diesel engines, including DieselRX, NGK, and more!

Injectors and Turbos
Since 2013, GMP Automotive Inc. has been recognized as Apex's premier diesel repair facility. We specialize in rejuvenating worn-out, high-performance injectors and turbos within GM, Chevy, Dodge, and Ford trucks. These components are prone to generating unwanted noise or expelling excessive exhaust. A failing injector can lead to poor fuel economy, glow plug complications, and reduced performance, impacting your truck or jeep both on and off the road.

Jeep and Truck Diesel Exhaust Repair
For any diesel truck or jeep, the exhaust system plays a crucial role in directing exhaust gasses away from the internal combustion engine and dispersing them into the atmosphere. This system can be customized to enhance engine performance, modify muffler sound, or reduce emissions. Regular maintenance is crucial to optimizing your diesel GM, Chevy, Dodge, or Ford truck or Jeep's exhaust system.

Diesel Maintenance FAQs


What maintenance is required for a diesel engine?

Diesel engines crank up the heat compared to their gasoline counterparts. This hotter environment means they're thirsty for fresh oil more often, demanding regular changes and quality checks. To keep them humming through winter, a splash of liquid additive can be their best friend, both during those chilly months and in the spring thaw.

How often should diesel injectors be serviced?

While 95,000 miles is the general lifespan for diesel fuel injectors, don't blindly stick to that number! Your specific car's make, model, and driving habits can significantly impact when they need replacing. Keep an eye out for warning signs like rough idling or decreased fuel efficiency, and consider scheduling a checkup even before hitting the 95,000-mile mark.

How long does a diesel engine last?

A well-maintained diesel engine is a mileage marathon runner. Expect 1 million to 1.5 million miles before major repairs, and some makes and models even boast 30 years of service on the road. That's more than twice the average lifespan of a gasoline engine, thanks to their robust construction and efficient combustion process.

Awesome service and highly skilled technicians! My 18 year old Ford diesel was experiencing issues and I sought out GMP to help me diagnose the power loss. Online forums had more than 12 things that could have been the cause, which worried me about a possible rabbit hole this could be on such an old truck. Dave B at GMP listened carefully to the concern, came up with a plan and dug in the resolve it. A little scary for me, because the entire cab of the truck had to come off to access the turbo, where the problem resided - but Dave set me at ease and showed professionalism and calm. Ultimately the work Dave did resolved the issue and hope to get another 5 or more years out of the truck! Dave also recommended a few other items, while the cab was off, that made great sense to get done at the same time. Thank you Dave and the entire GMP Automotive group for such great work! You have earned a long term customer that will be reaching out for my general and difficult maintenance in the future!

Fixed a longtime steering issue on my Dodge Charger. Replaced the rack and pinion along with parts of the suspension for a reasonable price. Will definitely be back again for potential problems in the future.
