Signs Your Diesel Needs Service

Diesel engines are known for being durable, but even the toughest ones show signs when something’s not right. Catching these symptoms early can save you from expensive repairs later.

Here are a few signs it’s time to visit your local diesel mechanic:

Hard Starting or No Start: This could mean weak glow plugs, low compression, or fuel delivery issues.
Loss of Power: Often caused by a clogged fuel filter, turbo problems, or injector failure.
Excessive Smoke:
- Black smoke may indicate too much fuel.
- White smoke could signal unburned fuel.
- Blue smoke might mean oil is burning.
Rough Idle or Stalling: Usually linked to injector or air intake issues.
Check Engine Light: Always worth investigating—it can point to anything from EGR valve issues to turbo faults.
Poor Fuel Economy: A drop in mileage can signal inefficiency somewhere in the system.

If you’ve noticed any of these symptoms, don’t wait until it gets worse. RCC Automotive’s expert technicians can diagnose and fix the issue before it leaves you stranded.

Specialized Diesel Brands We Service

Different diesel engines come with their own unique designs and maintenance needs. That’s why our team is trained to handle the top brands trusted by drivers across Michigan.

Cummins Repair

Known for legendary torque and long-lasting durability, Cummins engines are workhorses that demand precise care. We handle everything from fuel injector replacement to turbocharger repair, ensuring your Ram 2500 or 3500 continues to perform at its peak.

Duramax Repair

Duramax engines power some of the toughest Chevy and GMC trucks on the road. Our technicians are skilled at diagnosing DEF system issues, repairing glow plugs, and handling any fuel system concerns. Whether it’s an older LB7 or a modern L5P Duramax, we’ve got it covered.

Power Stroke Repair

Ford’s Power Stroke engines are powerful and efficient, but they rely on a complex high-pressure oil and fuel system. From injector replacement to EGR cleaning, we perform every repair with precision to keep your Super Duty running like new.

Preventive Diesel Maintenance Keeps You Rolling

The key to keeping your diesel strong is regular maintenance. Diesel engines can run for hundreds of thousands of miles when properly maintained, but skipping basic services can lead to premature wear and costly failures.

Here are a few maintenance steps we recommend:

Schedule oil changes and filter replacements regularly.
Replace fuel filters before they become clogged.
Keep your cooling system inspected and topped off.
Run quality diesel fuel to prevent injector buildup.
Allow the engine to idle briefly before shutdown to cool the turbo.
Have glow plugs and batteries tested before winter hits.

We make maintenance simple by inspecting your entire system every time you visit. This proactive approach helps us identify small issues early, allowing you to enjoy peace of mind on the road.
