FITMENT
- 2011-2016 6.6L Chevy GMC Duramax LML 2500 HD 3500 HD Diesel.
DESCRIPTION
Product Overview
-
The 2011–2016 LML Duramax uses a complex EGR system that constantly recirculates abrasive exhaust soot back into your clean intake, mixing with oil to form a thick, engine-choking sludge. Over time, extreme thermal cycles cause the internal cooler passages to crack.
- Once cracked, coolant leaks directly into your intake, leading to mystery coolant loss, white smoke, or even catastrophic engine hydrolock. This heavy-duty kit completely removes the failure-prone cooler assembly to safeguard your engine and restore its breathability.
Key Features
- Premium Billet & Stainless Steel Build: Features a CNC-machined anodized aluminum intake plate and heavy-duty stainless steel exhaust plate.
- Zero Carbon Soot Build-Up: The factory EGR recirculates abrasive soot back into clean intake air. Blocking this cycle prevents thick, oily sludge from clogging intake manifold and grid heater.
- Lower EGTs & Coolant Temps: By stopping hot exhaust gas from recirculating, this kit drops Exhaust Gas Temperatures. Additionally, our custom coolant hose accelerates flow to lower overall engine temperatures.
- Quicker Turbo Spool & Response: Sealing off the factory EGR bypass leaks routes 100% of exhaust gas directly through the turbocharger, enabling faster boost buildup and sharper throttle response.
FAQ
Q: Can an EGR delete prevent expensive coolant leaks and engine damage?
A: Yes, The factory EGR valve continually bleeds off valuable exhaust pressure. By removing this system and sealing it with block-off plates, 100% of the exhaust gas is routed directly to the turbocharger, eliminating turbo lag and making acceleration much sharper.
Q: What is the main benefit of an EGR delete for my engine's lifespan?
A: The factory EGR reroutes abrasive soot back into your clean intake. When this soot mixes with oily crankcase vapors, it forms a thick, concrete-like sludge that chokes your intake valves. An EGR delete ensures your engine breathes only clean, fresh air.
Q: Does an EGR delete help my truck run cooler when towing?
A: Yes, Instead of recirculating hot exhaust gases back into the combustion chambers, deleting the EGR keeps cylinder temperatures down. This protects internal engine components and keeps your coolant temperatures lower under heavy loads.
Q: Why should I do an EGR Delete and a DPF Delete at the same time?
A: To fix both intake and exhaust restrictions at once. The EGR delete stops dirty soot from choking your intake, while the DPF delete removes backpressure and hot "regen" cycles from your exhaust. Together, they let your engine breathe clean and exhale freely.
