Diesel Services at Jr. Auto Repair

At Jr. Auto Repair, 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 2010, Jr. Auto Repair has been recognized as Orlando'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 operate at higher temperatures than gasoline engines, requiring frequent oil changes and quality checks to maintain performance. Adding a liquid additive during the colder months and into the spring can also greatly benefit their operation.

How often should diesel injectors be serviced?

The recommended service interval for diesel fuel injectors is around 95,000 miles, but this can vary based on your vehicle's model, make, and your driving habits. Watch for signs such as rough idling or a drop in fuel efficiency as cues to perhaps service the injectors sooner than the mileage guideline suggests.

How long does a diesel engine last?

With proper maintenance, diesel engines can achieve 1 million to 1.5 million miles of service or about 30 years of reliable performance, significantly outpacing the lifespan of gasoline engines. Their durability is enhanced by their strong build and efficient combustion process.

What our clients are saying about us

We have established longterm and stable partnerships with various clients thanks to our excellence in solving their automotive needs!

Jr. Auto Repair is one of the more honest mechanic shops that you'll find in Orlando. They're a small, independent, family owned company that doesn't try to pull the wool over your eyes like some of the bigger, multi-branch companies tend to do. To clarify, I had only moved into Orlando proper this week and was looking over my options. Not only did Jr. take a look at my car thorughly but gave me a list of what I needed and didn't need done after looking at the receipt we got from Mavis for an oil change -one of said larger mechanic chains- and gave us a far more reasonable price for the job on everything else that needed to be done and had even gave us a ride back to my apartment sense we had no other rides available. To top it all off, it was all done in the same day and I didn't find a single thing wrong with the car after the fact. Everything was where it was, keys were under the matt and the car ran smooth. He gave us an idea of what we'll need in the future several months from now, estimated price, etc. They're fairly nice and reasonable and I can certainly see myself coming back to these guys whenever I'm having issues with my car. Best of all, pretty close to where I live too. Wholeheartedly recommend this shop over bigger brands. As far as local mechanics go, you can't go wrong. quotes-image
