Diesel Exhaust Treatment – Stage 2: SCR & DEF System for NOx Reduction | GM Specialist

In Stage 2 of diesel exhaust treatment, we break down the Selective Catalytic Reduction (SCR) system and Diesel Exhaust Fluid (DEF), which help reduce nitrogen oxide (NOx) emissions in modern diesel engines. This technology is essential for meeting EPA emission standards while maintaining fuel efficiency and engine performance.

At GM Specialist, we specialize in diesel exhaust diagnostics, NOx sensor troubleshooting, and DEF system repairs for Chevrolet, GMC, Duramax, and other diesel vehicles.

What You’ll Learn in This Video:
✅ How the SCR system reduces NOx emissions in diesel engines
✅ The role of Diesel Exhaust Fluid (DEF) in exhaust treatment
✅ Why NOx sensors and DEF dosing are critical to engine performance
✅ Common SCR and DEF system failures and how to diagnose them
✅ How to properly maintain the SCR system for longevity

Common SCR & DEF System Problems Covered:
🔹 DEF system faults and check engine lights
🔹 NOx sensor failures causing reduced power mode
🔹 Incorrect DEF mixture leading to emission faults
🔹 Crystallization in DEF injectors or clogged dosing valves
🔹 Poor DEF quality warnings and system contamination issues
