What are the basic maintenance required for a diesel fuel system?

Engine contaminants can wreak havoc on fuel injectors, impacting performance and fuel economy. Regular oil changes, by acting as a filtration system, prevent this buildup and ensure optimal injector function. Additionally, timely fuel filter replacements further protect against injector clogging, contributing to smooth engine operation and maximum efficiency.

Q: 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.

Q: 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.

Q: 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.

Diesel Services at Perez Tire Auto Care

At Perez Tire Auto Care, 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 1986, Perez Tire Auto Care has been recognized as Louisville'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.

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.

What Our Customers Are Saying

Let me start by saying I could not be more satisfied with the service that I received at Perez Auto (Formerly Exhaust Pro). I had them redo a brake job that had been previously done by another shop that was a complete failure and this other shop wouldn’t even recheck my brakes when I told him something was just not right. So much for using them again for anything. Anyway, when I explained what I needed at Perez., They were more than happy to look at my brakes and try correct any problems, which they did . It turned out that I needed my original calipers and piston assembly replaced that was not done at the previous shop. My truck had over 500,000 miles on it and these were probably the original calipers. Jason, at Perez, couldn’t have been more Professional, if he tried. After he completed the right job, he took it out for a test drive, and felt like something still wasn’t right and went back and rechecked his work again, and found that one of the new calipers was defective, ordered a new one and replaced it, test drove it again, and everything felt OK to him. It has felt completely OK since driven it by me. Jason‘s attention to detail and his expertise was exemplary. I’ll finish by saying that it was worth every penny and driving 30 extra minutes to get to Perez instead of using another shop closer to my home. I have already recommended Perez to some other people, including my son-in-law, who has already had two brake jobs done at Perez and also has been been completely satisfied. I wish I could’ve given them more than five stars, so I guess this testimonial will have to do. Again, thank you Perez for your excellent service. As Arnold Schwarzenegger used to say “ I’ll be back”.
