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 1992, Protrans Automotive & Transmission Specialists has been recognized as Riverside'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.

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.

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.

These folks are awesome!!! I brought my prized, restored classic Mustang in for a new starter and flywheel replacement, which at first was a bit of a challenge because it's difficult to find mechanics willing and, moreover, knowledgeable of these older cars. They did not hesitate to accept the challenge and went ahead and did the repair. Unfortunately, five months later, both the flywheel and starter failed just a mile from the shop. Since the car was still operational (after a push start), I brought it by and was immediately met with assurance that the entire job, parts and labor, were covered under their warranty for a year, and in my case, being a AAA member, for two years. The gal at the front counter (Luz), who is super nice, said they would get it in the shop right away and see what had happened. A couple of days later, I met with Michael (the owner), who calmly reassured me that they always stand behind their work and would get the repair done, no matter what. In the end, they identified a couple of possible issues that may have caused the failure, and to make sure that it didn't happen again, they put together a higher-quality setup with better parts, and now the car operates better than ever. I highly recommend calling them first!

The wonderful team at ProTrans helped me out IMMENSELY when I called with an emergency. I had a kitten under my hood that I could not get out! After towing my car there, they helped out immediately and removed the little furball so I could return him to his home. Thanks again to this amazing group. I?ll definitely be bringing my car here for future tune ups. Great guys & great service.
