When to Service Your Fleet’s Diesel Engines

Prompt attention to engine issues helps avoid costly breakdowns and unscheduled downtime. Schedule an engine evaluation if your truck shows any of the following:

  • Loss of power or engine hesitations
  • Excessive smoke or unusual exhaust color
  • Rough idle or engine vibration
  • Overheating or cooling system concerns
  • Engine warning lights or diagnostic codes
  • Slow acceleration under load

Getting ahead of engine wear means better performance, greater uptime, and lower total cost of ownership.

Comprehensive Fleet Engine Services

Belts & Hoses Inspection & Replacement

Belts and hoses handle cooling, accessory power, and system pressure. We inspect for cracks, wear, and heat damage and replace components as needed to prevent failures on the road.

Cooling System Service

A healthy cooling system is essential for diesel engines under load. We flush and refill coolant, check radiators and water pumps, and inspect all related components to maintain proper temperatures during heavy use.

Diesel Fuel System Maintenance

Fuel system cleanliness impacts power and efficiency. We service fuel filters, check injectors, and ensure clean fuel delivery throughout the system to keep engines responsive.

Exhaust System Care

Your fleet’s exhaust system affects engine performance and emissions compliance. We inspect and repair exhaust components to maintain proper flow and reduce engine stress.

Water Pump Inspection & Replacement

Water pumps circulate coolant through the engine. A failing pump can lead to overheating and severe damage. We test pump operation and replace units that show wear or leakage.

Engine Diagnostics & Tune‑Ups

Using advanced diagnostic tools, we analyze engine performance data, identify trouble areas, and make precise adjustments to tune your diesel fleet engines for optimal power and economy.
Why Professional Engine Care Matters for Your Fleet

Diesel engines are powerful but complex machines. Regular engine work ensures stability under load, reduces the risk of failure during critical operations, and helps preserve resale value. Whether your vehicles haul materials, respond to emergencies, or support daily logistics, RG Diesel, LLC offers the expertise and equipment needed to maintain peak performance.

Fleet Engine Work FAQs

How often should fleet diesel engines be inspected?

Inspections at every scheduled maintenance interval or every 10,000 miles help catch issues early and prevent major repairs.

Can cooling problems damage the engine?

Yes. Overheating can lead to head gasket failures, warped components, and costly downtime.

Why is injector maintenance important?

Dirty or worn injectors reduce fuel efficiency and power and can lead to increased emissions.

Can you work on both gasoline and diesel fleet engines?

We specialize in diesel. Gasoline engines have different maintenance needs, but we can refer you to trusted partners if necessary.

At RG Diesel, we fix it right the first time with expert service, dependable workmanship, and honest communication you can count on.
