We provide repairs for:

Fuel Injection Problems: Faults with fuel injectors lead to misfires, reduced fuel economy, trouble starting the engine, smoky emissions and eventually engine failure. At Mac's Tire Pros & Auto Repair, we specialize in diagnosing and repairing fuel injection systems, ensuring optimal performance and functionality.

Turbocharger Failure: The turbocharger is responsible for making your vehicle more efficient and powerful, channeling energy that would otherwise be lost back to the engine. Turbochargers can be damaged by oil contamination, oil starvation, restricted airflow, unfiltered airflow and other causes, resulting in a loss of power, engine efficiency and eventually engine failure.

Clogged Diesel Particulate Filter (DPF): The DPF is responsible for catching exhaust ash and other contaminants, reducing diesel emissions. A process called "DPF Regeneration" occurs under certain circumstances to burn the contaminants away. If DPF regeneration doesn't occur, it can cause a DPF blockage, resulting in poor engine performance. There can be many reasons why a DPF clogs, the team at Mac's Tire Pros & Auto Repair can identify and repair what your diesel needs to continue functioning properly.

Engine Overheating: If your engine begins to overheat, it can cause serious damage. A coolant fluid leak, bad water pump, broken hose, thermostat, clogged radiator or blown head gaskets can all cause a diesel engine to overheat. Contact the team at Mac's Tire Pros & Auto Repair of Troy, VA for diagnosis and repair.

Bad Glow Plugs / Relay: Diesel engine glow plugs are responsible for heating incoming fuel and air, contributing to efficient fuel combustion to start the engine. If you have a faulty or malfunctioning relay or glow plugs, it may result in a "hard start" or even failure to start. Contact Mac's Tire Pros & Auto Repair of Troy VA for glow plug system diagnosis and services.

Electrical: Charging, Starting and Operating Systems: These systems are essential for proper performance. Many of the electrical operating systems require 12 Volt DC power and high amperage output. Ensuring these systems are well maintained will improve ability to start your vehicle in extreme conditions and keep all systems operating as designed to maximize performance in all conditions. Diesels also require several integral computer components to communicate with one another. These systems require experienced interface, both human and proper operating system software to diagnose when these systems have issues.

Diesel Engine Maintenance: Preventative maintenance is important to preserve the life and reliability of your vehicle. Check your owner’s manual or call Mac's Tire Pros & Auto Repair of Troy, VA to determine recommended maintenance schedules.
