L5P Duramax EGR Delete Kit: Stop Coolant Leaks & Save Your Engine

L5P Duramax EGR Delete Kit: Stop Coolant Leaks & Save Your Engine

The L5P Duramax's Silent Killer: EGR System Failure

If you own a 2017-2023 L5P Duramax, you're likely familiar with:
✔️ Mysterious coolant loss (disappearing with no visible leaks)
✔️ White exhaust smoke (burning coolant from failed EGR cooler)
✔️ Reduced power & MPG (carbon-choked intake)
✔️ $4,000+ repair bills (EGR cooler replacement costs)

The factory EGR (Exhaust Gas Recirculation) system is slowly destroying your engine - and most owners don't realize it until it's too late.

 

 

Why All L5P Duramax Engines Need an EGR Delete

1. Coolant Leaks Lead to Catastrophic Failure

The EGR cooler circulates coolant near 400°F exhaust gases. Over time:
→ Metal fatigues and cracks develop
→ Coolant leaks into exhaust (white smoke)
→ Worst case: Coolant enters cylinders → hydro-lock → blown engine

2. Carbon Buildup Chokes Performance

EGR pumps soot back into your intake, causing:
→ Clogged intake manifolds (30% airflow reduction)
→ Sticky turbo vanes (reduced boost)
→ Oil contamination (accelerated engine wear)

3. Heat Soak Damages Critical Components

Recirculated exhaust gases create:
→ Higher cylinder temps (piston/ring wear)
→ Overworked intercooler (heat-soaked intake air)
