L5P Duramax EGR Delete Kit – Fix Coolant Leaks & Restore Power (2017-2023)

DynoVox L5P Duramax EGR Delete Kit insights

Is Your L5P Duramax Suffering from EGR Problems?

If you own a 2017-2023 L5P Duramax, you’ve likely experienced:

  • Unexplained coolant loss (EGR cooler leaks)

  • Reduced power and throttle response (carbon-clogged valves)

  • Check engine lights (P0401-P0406 codes)

  • Risk of hydro-lock (coolant entering cylinders)

The factory EGR (Exhaust Gas Recirculation) system is the culprit—and the only permanent fix is deleting it.

Why Delete the EGR on an L5P Duramax?

  1. Prevents Coolant Leaks – The factory EGR cooler cracks over time, leaking coolant into the exhaust or intake.

  2. Eliminates Carbon Buildup – Soot and oil sludge reduce engine efficiency and lifespan.

  3. Restores Lost Power & MPG – Cleaner airflow = better combustion.

  4. Reduces Engine Heat – Lower EGTs (exhaust gas temps) mean safer towing.
