Not sure if something’s wrong? Watch for these signs:

• Hard starting, especially in the morning
• Loss of power while driving
• Excess black, white, or blue smoke
• Knocking or unusual engine noise
• Drop in fuel economy
• Check engine light stays on

If you notice any of these, don’t wait. Diesel problems rarely fix themselves.

Whether your truck is your daily driver or part of a work fleet, keeping it in good shape matters. Here’s what we handle.

Diesel Engine Diagnostics

If your check engine light is on or your truck just doesn’t feel right, diagnostics is the first step.

We use diesel-specific scan tools and testing equipment to check:

• Fuel system pressure
• Injector performance
• Turbo boost levels
• Emissions system function

Most people assume it’s one issue. Often, it’s a combination. We find the root cause so you don’t waste money fixing the wrong thing.

Diesel Engine Repair

Once we know what’s wrong, we get to work.

Common diesel repairs include:

• Fuel injector replacement
• High-pressure fuel pump repair
• Head gasket and internal engine repairs
• Cooling system fixes
• Oil leak repairs

We use OEM or high-quality aftermarket parts so your repair lasts.

Diesel Engine Maintenance

Regular maintenance is what keeps diesel engines running for hundreds of thousands of miles.

Our maintenance services include:

• Diesel oil changes
• Fuel filter replacement
• Air filter checks
• Fluid inspections
• Preventive maintenance scheduling

Skipping maintenance is one of the biggest mistakes we see. It leads to expensive repairs that could have been avoided.

Diesel Performance Tuning

Want better power or fuel economy?

We offer safe, reliable tuning options that can:

• Improve throttle response
• Increase towing power
• Help fuel efficiency

We don’t push extreme tuning that damages your engine. We focus on real-world performance you can use every day.

Fuel System Repair for Diesel Engines

Your diesel engine depends on precise fuel delivery. Even small issues can cause big problems.

We service:

• Fuel injectors
• High-pressure fuel pumps
• Fuel lines and filters

If your truck is hard to start, idles rough, or loses power under load, there’s a good chance the fuel system is involved.

Turbocharger Repair and Replacement

Turbochargers help diesel engines produce more power. But when they fail, you’ll notice right away.

Signs of turbo issues:

• Loss of power
• Whining noise
• Excess smoke

We test boost pressure and inspect components like intercoolers and hoses before replacing anything. Sometimes the turbo isn’t the real issue. We make sure before you spend money.

DPF and EGR System Service

Modern diesel engines have emissions systems that can get clogged over time.

We handle:

• DPF cleaning and regeneration
• EGR valve service and replacement
• DEF system checks

Short trips and stop-and-go driving around places like Beardsley Recreation Center can actually speed up DPF clogging. That’s something many drivers don’t realize.

Diesel Oil Change and Fluid Services

Diesel engines need specific oil and fluids to handle higher stress.

We use:

• High-quality diesel engine oil
• Proper DEF (diesel exhaust fluid)
• Manufacturer-recommended coolant

Using the wrong fluids is a common issue. It can shorten engine life without obvious warning signs.
