HEAVY-DUTY TRUCK EGR & DPF REPAIR

YOUR EGR SYSTEM EXPLAINED

Your Exhaust Gas Recirculation (EGR) system is a major system integrated into your engine. Using an EGR valve and EGR cooler, cooled exhaust fumes are recirculated into your combustion chamber in an effort to lower your combustion temperature. This lower combustion temperature allows for a significant reduction in NOx production.

If your EGR system is malfunctioning, the first thing you’ll notice is either a check engine light or a malfunctioning indicator lamp. These two signs are very important to pay attention to. If EGR system issues are left unchecked for too long, the damage in the long term may increase to the point where repairs cost thousands more.

COMMON EGR SYSTEM ISSUES

One of the most common EGR system issues is a malfunctioning EGR valve. Since your EGR valve is constantly exposed to unfiltered emissions, carbon and soot may build up on the valve and cause it to seize up. A valve that’s stuck open will likely cause engine issues such as stalling, a rough idle, hard starts, and poor performance. Other EGR system issues include a malfunctioning EGR cooler and coolant loss.

YOUR DPF EXPLAINED

Your Diesel Particulate Filter (DPF) is responsible for capturing soot and other matter before it enters our natural atmosphere. Your DPF is incorporated directly into your exhaust tubing system, meaning all of your exhaust must pass through your DPF before it exits the system entirely. DPFs have finite storage, meaning they need to be cleaned once every few years.

FORCED REGENERATION SERVICES

At Hook-N-Haul, we provide a forced regeneration service for DPFs of all kinds. For those who are unaware, forced regeneration allows you to override your ECM and activate your DPF regeneration process manually.
