Step 1 :

1.Disconnect batteries.Remove the passenger side inner wheel cover to drain the engine coolant, and disconnect the lower radiator
pipe by removing the metal clip.
2.Remove the intake pipe from the filter to the plastic turbine interface.Gently pry out three rubber washers and remove the bellows and filter.

Step 2 :

Install the new exhaust block O-plate using the factory gasketand provided bolts. Two M8 x 20 hexagon head bolts will be screwedin from the back, and two M10 x 20hexagon head bolts will secure the bracket in place.

Step 3 :

1.Remove the plastic cover from the wiring harness and plug the wiring harness under the new inflation tube.
2.Install a new intake pipe. Slide the tube into the rubber tube and tighten the bent end with bolts.

Step 4 :

Transfer the pressure sensor from the raw material filling tube to the new filling tube. The installation bracket needs to be rotated 1800 on the sensor in order to be installed onto the new inflation tube.

Step 5 :

1.Use the newly provided coolant hose and hose adapter to connect the two coolant ports previously connected to the EGR cooler. Secure the hose with the provided hose clamp.
2.Replace the manifold bolts with the provided vertical bolts.

Step 6 :

1.Install the bracket. The M10 bolt will be screwed into the support bolt. Secure the transmission dipstick to the bracket using 1/4-20 bolts, nuts, and washers.
2.The bracket will hold the coolant hose connector in place.

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: Does this kit require complete removal of the EGR coolers, or is it just a blocking kit?

A: It is a complete cooler removal kit. This kit completely remove the entire, bulky dual-cooler assembly from your engine bay. This clears up massive amounts of space on the passenger side of the motor, making future maintenance much easier.

Q: How does deleting the EGR improve my truck's performance?

A: The factory EGR valve continually bleeds off valuable exhaust pressure. By removing this system and sealing it with block-off plates, the exhaust gas is routed directly to the turbocharger, eliminating turbo lag and making acceleration much sharper.

Q: Why should I replace the passenger-side up-pipe during an EGR delete?

A: To prevent exhaust leaks and clean up the engine bay. The factory up-pipe has a bulky branch (EGR riser) that becomes useless once the EGR is deleted. Swapping to a up-pipe eliminates this failure-prone branch entirely, preventing future cracks and exhaust leaks.

Q: Why does this kit include a "3-terminal (Y-shaped)" coolant hose?

A: The factory EGR coolers run engine coolant to cool exhaust gases. When removed, our custom 3-terminal hose perfectly links the factory heater core and engine coolant ports together, ensuring a leak-free bypass with zero cooling issues.
