Factory Scheduled Maintenance

Following manufacturer-recommended service intervals is essential for optimal truck performance and longevity. We offer 30K, 60K, and 90K mileage services, including inspections, fluid changes, and component replacements to ensure your diesel stays in top shape.

Fuel System Maintenance

A clean, efficient fuel system is vital for performance and fuel economy. We inspect and replace fuel filters, check injectors, and service fuel pumps to keep your engine running smoothly and prevent clogs or failures.

Cooling System Care

Diesel engines generate significant heat, making cooling system maintenance critical. We inspect and service radiators, thermostats, coolant levels, and hoses to prevent overheating and engine damage.

Brake System Inspections

Braking performance is crucial for safety, especially when hauling heavy loads. We inspect and replace brake pads, rotors, calipers, and brake fluid to ensure your truck stops safely and efficiently.

Transmission Maintenance

Regular transmission service helps prevent slipping, overheating, and shifting issues. We inspect transmission fluid levels, filters, and seals, ensuring smooth and reliable operation.

Steering & Suspension Checks

A well-maintained suspension keeps your truck stable and comfortable on the road. We inspect and service ball joints, tie rods, track bars, and shocks to prevent excessive wear and handling issues.

Whether your A/C is blowing warm air, making unusual noises, or failing to turn on, we provide full-service A/C repairs. Our services include system diagnostics, refrigerant recharges, leak detection, and component replacements, ensuring you stay cool and comfortable no matter how hard your truck works.

Electrical System Testing

A reliable electrical system is essential for ignition, lighting, and onboard diagnostics. We test batteries, alternators, wiring, and control modules to ensure your truck operates efficiently.

Filter Replacements

Dirty filters can restrict airflow, reduce efficiency, and cause engine strain. We replace air, fuel, and cabin filters with OEM-grade parts to protect your engine and maintain peak performance.

Comprehensive System Inspections

Our multi-point inspections identify potential issues before they turn into costly repairs. We thoroughly check your truck’s fluids, belts and hoses, ensuring optimal performance, reliability, and comfort on the road.

The Benefits of Regular Diesel Maintenance

Routine diesel truck maintenance is more than just an oil change—it’s an investment in your truck’s performance, safety, and longevity.

  • Prevent Costly Repairs: Catch issues early before they turn into expensive breakdowns.
  • Improve Fuel Efficiency: A well-maintained fuel and air system ensures better MPG and engine performance.
  • Enhance Safety: Proper maintenance keeps brakes, suspension, and steering in top condition.
  • Extend Engine Life: Regular servicing helps prevent wear and tear, ensuring your diesel lasts longer.

When Is It Time for Diesel Maintenance?

Your truck’s maintenance schedule depends on mileage, usage, and driving conditions. However, key indicators that your truck needs service include:

  • Mileage-Based Maintenance: Scheduled 30K, 60K, and 90K services keep your truck on track.
  • Heavy-Duty Usage: Towing, off-road driving, and extreme conditions increase wear and may require more frequent servicing.
  • Dashboard Warning Lights: Ignoring warning lights can lead to major repairs—get diagnostics early.
  • Performance Changes: Loss of power, rough idling, or shifting issues indicate it’s time for service.

Our experts create customized maintenance plans based on your truck’s needs, ensuring maximum efficiency and longevity.
