EGR and DPF Services

EGR Valve Replacement: The EGR valve is vital for reducing emissions. Our technicians specialize in precise EGR valve replacements, addressing issues such as carbon buildup and valve malfunctions, ensuring your truck meets emission standards.

DPF Cleaning and Regeneration: The DPF filters out particulate matter from exhaust gases. Our services include thorough DPF cleaning and regeneration, preventing clogs and maintaining optimal filter efficiency for improved engine performance.

EGR Cooler Inspection and Repair: Our experts conduct meticulous EGR cooler inspections and repairs, addressing coolant leaks or clogs that may affect the EGR cooler's functionality.

DPF Sensor Diagnostics: Our diagnostic services focus on DPF sensors, identifying issues such as faulty readings or sensor malfunctions, ensuring accurate data for efficient filter regeneration.

The Importance of DPF Cleaning

Regular DPF cleaning is essential to maintain optimal filter efficiency. Over time, soot and particulate matter can accumulate, leading to decreased performance and potential engine damage. Our DPF cleaning services ensure proper filter function, preventing clogs and promoting a cleaner and more efficient exhaust system.

Common EGR Issues

Common EGR issues include carbon buildup, valve malfunctions, and coolant leaks in the EGR cooler. If you notice decreased engine performance, increased emissions, or warning lights on the dashboard, these could be signs of EGR issues. Timely inspection and repairs are crucial to prevent further damage and ensure compliance with emission standards.
