Expert Diesel Engine Service for Your Truck or SUV

Light-duty diesel vehicles—like those powered by Duramax, Cummins, or Power Stroke engines—are built for performance and longevity. But like any engine, they require regular attention to avoid costly breakdowns. Our diesel-certified technicians provide precise diagnostics, factory-grade repairs, and ongoing maintenance plans that keep your engine running efficiently.

What Is Light-Duty Diesel?

Light-duty diesel vehicles typically include:

• Pickup trucks (F-250/F-350, Silverado 2500, Ram 2500)

• Diesel SUVs

• Diesel-powered vans (like Sprinter and Transit models)

• Passenger vehicles with diesel variants (Chevy Cruze Diesel, Jeep Grand Cherokee EcoDiesel)

If your diesel-powered vehicle weighs less than 14,000 pounds, it qualifies as light-duty—and we’re the shop to trust for every mile it runs.

Complete Light-Duty Diesel Services We Offer

Our Dawsonville shop is fully equipped to handle all aspects of diesel engine service, from minor issues to major repairs. We use state-of-the-art diagnostics and only high-quality parts for reliable, long-lasting results.

Diesel Diagnostics & Check Engine Light

Diesel engines run differently than gas engines and require specialized tools. If your check engine light is on, we use advanced diesel diagnostic software to find and fix the root of the problem quickly.

Oil & Fuel Filter Changes

Diesel engines rely heavily on clean oil and fuel. We provide timely oil changes using high-quality diesel-rated oils, and we replace fuel filters to maintain efficiency and prevent injector damage.

Glow Plug & Injector Service

Cold starts or poor fuel economy? It could be your glow plugs or injectors. We inspect, test, and replace faulty components to restore peak performance.

Turbocharger Inspection & Repair

Many light-duty diesels are turbocharged. We inspect turbochargers for wear, boost leaks, and performance loss, and we repair or replace them when needed.

Exhaust After-Treatment Service (DPF, EGR, SCR)

Modern diesels include emissions components like Diesel Particulate Filters (DPF), Exhaust Gas Recirculation (EGR), and Selective Catalytic Reduction (SCR). We clean, repair, or replace these components as needed to keep your system compliant and efficient.

Cooling System & Radiator Repairs

Diesels run hot under pressure. We provide coolant flushes, water pump service, radiator replacements, and thermostat repairs to protect your engine from overheating.

Transmission & Drivetrain Repair

Our shop also handles automatic and manual transmission repairs, transfer case service, and axle inspections to keep your diesel moving with power.

Air & Fuel System Repairs

We test air intake systems for leaks or clogs, clean throttle bodies, and inspect diesel fuel systems for pressure issues, leaks, or dirty filters.

Brands We Service

Our diesel mechanics are trained to work on the most popular light-duty diesel engine brands:

• Duramax (Chevrolet/GMC 2500HD/3500HD)

• Power Stroke (Ford F-Series Super Duty trucks)

• Cummins (Ram 2500/3500 trucks)

• Mercedes-Benz & Freightliner (Sprinter vans)

• EcoDiesel (Ram 1500, Jeep Grand Cherokee, Wrangler 4xe)

• VW TDI and other diesel passenger cars

Whether it’s a work truck, fleet van, or diesel daily driver, Tower Auto Repair has you covered.

Common Diesel Engine Issues We Repair

Even strong diesel engines develop problems over time. We frequently diagnose and repair:

• Hard starts or long crank times

• Black smoke from the exhaust

• Loss of power or fuel efficiency

• Turbo lag or boost issues

• Glow plug faults or sensor errors

• Check engine or DEF light warnings

• Clogged DPF or faulty EGR valves

• Fuel injector failure

• Overheating under load

If your diesel isn’t performing like it used to, bring it in for a full inspection before it turns into a major problem.

Signs You Need Diesel Engine Service

Not sure whether it’s time for light-duty diesel service? Watch for these warning signs:

• Unusual engine noise or knocking

• Excessive exhaust smoke (white, black, or blue)

• Poor throttle response or delayed acceleration

• Frequent stalling or difficulty starting

• Decreased towing capability

• Dashboard warning lights (Check Engine, DEF, or DPF)

• Strong fuel odor or visible fuel leaks

• Overheating while hauling or idling

These symptoms can be caused by everything from minor filter clogs to failing injectors or EGR problems. The sooner you bring it in, the easier (and more affordable) it is to fix.

Frequently Asked Questions (FAQs) About Light-Duty Diesel Service & Repair

1. How often should I service my light-duty diesel engine?
Oil changes are typically needed every 5,000–7,500 miles, and fuel filters should be replaced every 15,000–30,000 miles. Follow your manufacturer’s maintenance schedule or ask us to set up a custom plan for your needs.

2. What causes a diesel engine to lose power?
Loss of power may come from clogged fuel filters, bad injectors, turbo problems, or dirty air filters. We use diagnostics to find the exact cause.

3. Can I still drive with a clogged DPF?
It’s not recommended. A clogged DPF can cause high exhaust pressure and poor fuel economy. We clean or replace DPF units and perform regeneration when needed.

4. Why is my diesel blowing black smoke?
Black smoke usually means unburned fuel, which could be due to injector problems, air restriction, or a turbo issue. It’s best to have it inspected ASAP.

5. What is DEF and why is it important?
DEF (Diesel Exhaust Fluid) is part of the emissions system in many modern diesels. It helps reduce NOx emissions. Running out of DEF can put your engine into limp mode.

6. My diesel cranks but won’t start—what’s wrong?
Possible issues include glow plug failure, fuel delivery problems, or low compression. Our diagnostic tools can quickly pinpoint the issue.

7. How long does a diesel engine last?
With proper maintenance, light-duty diesel engines can last 250,000 to 500,000 miles. Preventative service is key to longevity.

8. Why does my diesel use more fuel than usual?
Fuel efficiency problems may stem from dirty injectors, air filter issues, turbo wear, or poor fuel quality. Let us run a performance check.

9. Can you service diesel fleet vehicles?
Yes. We provide light-duty diesel fleet maintenance, diagnostics, and repair services. Ask about our fleet service programs.

10. Is diesel engine repair more expensive than gas engine repair?
Some parts and labor are more expensive, but diesel engines require fewer repairs over time if maintained properly. We offer fair pricing and accurate quotes.

Performance Service for Diesel Pickups

Light-duty diesel trucks are known for their torque, towing power, and long-lasting durability—but only if they’re maintained properly. We handle everything from routine oil and fuel filter changes to transmission flushes, cooling system service, and DEF system maintenance. Keeping your 6.7L Power Stroke, 6.6L Duramax, or 6.7L Cummins in top condition means sticking to a solid maintenance plan—and we’re here to help you stay on track.

Diagnosing and Fixing Diesel-Specific Issues

Each diesel engine has its own set of common problems, and we’ve got the experience to handle them. If your Power Stroke is showing signs of injector failure, your Cummins is blowing excessive smoke, or your Duramax is struggling with fuel pressure, we’ll track down the problem fast. Our diagnostic tools are up to the task, and our technicians know what to look for in diesel-specific systems.

Drivability and Powertrain Concerns

When something feels off—like sluggish acceleration, odd shifting, or reduced towing capability—it’s time to take a closer look at the powertrain. We inspect and repair transmission issues, drivetrain components, and turbocharger systems to make sure your diesel truck responds the way it should. Whether you drive a Silverado HD, an F-250, or a Ram 2500, we’ll restore performance and drivability without cutting corners.

Cooling, Emissions, and Electrical Repairs

Diesel engines generate a lot of heat and rely on complex emissions systems. From radiator and EGR cooler repairs to cleaning DPF filters and replacing sensors, we’re equipped to keep your truck running clean and cool. Electrical issues in today’s diesel trucks—like faulty glow plugs or wiring faults—are no problem for our experienced crew.
