Most heavy trucks today are equipped with many different components simultaneously to work with the engine and the exhaust.
This combination aims to minimize emissions of environmental pollution. There are many built-in components, then. The minimum sustainable gain is for powerful performance and good fuel economy for your vehicle.
Most prominent for bringing valuable features, it is impossible not to mention EGR.
Exhaust gas recirculation is an essential item for improving vehicle performance. In this article, I will introduce all the information about the LMM EGR delete kit.
Please keep an eye out for it!
A Brief Overview Of EGR Delete
EGR is a crucial component, working to minimize pollutant emissions by recirculating some of the exhaust gases back into the engine.
This process helps keep the engine cool while maintaining good fuel efficiency.
But, it also causes some negative issues related to cooling, leakage, or valve blockage and forces the operator to choose to remove it.
The removal is performed using a dedicated eraser to delete all systems. Clearing the EGR provides certain benefits for improved engine performance, serviceability, and significant fuel economy.
The motor without EGR ensures optimal and more efficient operation.
When exhaust gas is through the engine, dust and coal particles accumulate over time and directly affect the vehicle’s ability to work.
And so, you will lose a large amount of money to maintain your beloved car.

- Remove the resonator on the top by gradually loosening the tube clamp at the bottom of the resonator. At the same time, removing the pin on the front of the resonator is necessary.
- Disconnect the recharge cord on the alternator and remove the plastic clip to secure the harness to the plastic wire.
- Open the plastic box on the heating grid and disconnect the power cord.
- Next, remove the bolt and nut to secure the plastic rope.
- Disconnect the connector wire on the front of the heating grille inlet. At the same time, remove the bolt securing the cables connecting to the intake side.
- Remove the plastic clip
- Peel off the metal, retain the clamp on the plastic intercooler and disconnect the molded plastic mouth.
- Remove the connector wire and the four bolts that hold the front most of the molded cooler piping to the medial.
- Carefully remove forward most of the excess of the intercooler piping.
- Remove the small tube attached to the molded intake next to the heater grille.
- Continue to unscrew the four nuts and two bolts holding the main information. And it can be easier to remove suction from your car if you remove the two extra studs.
- Remove the PVC pipe
- Remove the plastic turbo by loosening the clamp that secures the mouthpiece to the turbo.
- Removed two temperature sensors from the system
- Disconnect all running coolant to the system.
- Remove the cooler
- Then you need to disconnect the temperature sensors at the electrical connector and remove them from the car.
- Remove the valve fixed with two bolts
- Remove the last cool water lines.
- Install a new exhaust
- The U-install clamp is from the cooling hose using the included hose.
- Remove the plastic cap from the harness to proceed with the harness under the new intake manifold.
- Install new intake manifold
- It is necessary to transfer the sensor pressure from the reserve charge pipe to the newly installed charging line.
- Reconnect the charging cord back to the top of the generator.
- Restore the resonator mounting settings.
- Install the air intake and plug in the sensor air block.
- After everything is done, start the car with fresh coolant.
- Reconnect the battery
- Start the engine and check its operation.
How Much Does It Cost To Rebuild A LMM Duramax?
