Diesel-powered trucks and SUVs are built for strength, longevity, and efficiency, making them a popular choice for work and daily driving. Whether your vehicle runs on a Cummins, Power Stroke, or Duramax engine, keeping up with maintenance and repairs is essential to ensuring top performance. At Tune Tech’s Monroe Street location, we provide expert light-duty diesel repair in Spokane, WA, handling everything from routine service to complex engine diagnostics.

Essential Maintenance for Diesel Vehicles

Light-duty diesel engines require specialized care to maintain efficiency and durability. Regular oil and fuel filter changes, coolant system checks, and glow plug inspections help prevent common issues such as overheating and hard starts. Air intake system servicing and EGR valve cleaning further enhance engine performance and longevity. Our team ensures your Cummins, Power Stroke, or Duramax engine runs at peak efficiency with factory-recommended maintenance.

Fuel System and Turbocharger Service

Diesel engines depend on high-pressure fuel injection and turbocharging to deliver optimal power and fuel economy. If you notice hesitation, excessive exhaust smoke, or a drop in fuel efficiency, there could be an issue with the injectors, fuel pump, or turbo system. Turbo lag, boost pressure loss, or unusual engine noises can signal a failing turbocharger. We provide diagnostics and repairs to restore the power and reliability of your truck or SUV.

Exhaust and Emissions System Repairs

Diesel engines feature advanced emissions control technology, including diesel particulate filters (DPF), exhaust gas recirculation (EGR) systems, and selective catalytic reduction (SCR) components. If your truck struggles with excessive soot buildup, poor fuel efficiency, or frequent regeneration cycles, these systems may require servicing. Our technicians handle emissions-related repairs to ensure compliance with environmental standards while maintaining optimal performance.

Transmission and Cooling System Service

Diesel trucks endure heavy loads and high-torque demands, making a well-maintained cooling and transmission system essential. Overheating, slipping gears, or delayed acceleration can indicate worn transmission components or a failing radiator. Our shop provides transmission fluid changes, radiator repairs, and drivetrain servicing to keep your vehicle performing reliably under all conditions.
