Question 1: yes, it'll turn of the egr if done correctly

Question 2: because you kill the power to it and the egr stops working.

I did this on my ISX, two weeks ago I gained 1.1 mpg. I'm a believer. If you do it turn the key to the ON position wait 15 sec ( this allows the egr to fully close) then unplug tape the elec end.

Thank you Kevin and "the gang" so very much. Confirmed everything I've experienced since unplugging the worst so called engine emission reduction system ever forced upon the public.

Could someone clarify this procedure a little, as I'm just getting educated about an ISX, and EGR. Do we want to unplug a wiring connector at the solenoid? (looks kind of like an electric motor on the bottom of the EGR valve). I've already had to replace the EGR valve, as I've only had the truck a few weeks, (06 IH), and EGR valve stuck open, (was in open position when removed). Now I'd like to get my $900.00 back by unplugging it and getting better fuel mileage, if it truly works. If I had it to do over I would had kept the old valve just to see what it was made of, and to keep them from "rebuilding" it for say less than a hundred bucks, and charging the next guy $900. again.

I have heard that putting in a block works best. Can somebody tell me what tube needs to be blocked, where it is located etc. Thanks.

I did the unplug thing early on with my '06 ISX. It did great. Later I wanted to put on a larger throated intake manifold from PDI to eliminate any restriction. When it arrived, it had a steel plate for where the EGR tube hooks up the intake. Evidently so it could be used on a pre-egr ISX. So, I took advantage of that. Still hooked up the EGR tube to the intake so it "looked" normal, but installed the steel plate between the tube and the intake, effectively blocking off everything.

Later at a Cummins shop for another issue, they plugged the EGR back up. The EGR had been unplugged so long, it had carbon buildup and had "frozen" in place so that the EGR failed in the closed position. So I left it plugged up. I did all this between 300,000 and 400,000 miles. The engine has 870,000 miles on it now. Oil stays almost out of the bottle clean for 10,000 miles before starting to darken. MPG's in the mid 7's all the time. Don't need the EGR, don't want the EGR, and I am not going to replace the EGR.

I have a 2007 Peterbuilt cummins ISX and unplugged tgr EGR when new and ran the truck like this for 4 years and then ! day the Egr valve opened up and stuck in the open position I went to a Peterbuilt dealer and they took it off And welded it shut.I now have taken it right off along with the EGR cooler..Installed a new ECM with EGR delete and my ck engine lite is off..I can"t go to any cummins dealer or they may reflash my ECM so I get my work done at my local peterbuilt dealer...The only weak spot now is the turbo which doesn't last as the blades in the actuator warp and then have only 10 psi of Jake brake boost ,but the boost with load stays High..32psi.MY camshaft went at a million+ and had my inframe done..average 7.2 mpg in the summer...I intend to keep this tuck for a long time as I hear too many bad reports on the new engines....Let them experiment till they get it right which they will eventually ,but not at my expense............................

Deleting the egr is simple. The thing most people won't tell you is with the motor unplugged the ecm is supposed to derate something like 10% according to my cummins dealer.

The fix is get all the new gaskets needed to remove the egr valve there are videos on YouTube showing how to remove the valve.

With the valve off cut a disk from sheet metal that will fit in the groove on the bellows side (the side that go's to the egr cooler) place it in the groove and reinstall the valve and plug it back in.

Doing this let the valve work but not flow any egr gas into the cooler another benefit is no gas flowing no more problems of egr coolers cracking.

To eliminate the chance of a cracked cooler filling the intake tube take the fitting out of the bottom of the intake install a expandable freeze plug and cut the bend off.

By doing this you increase the flow of air eliminating the need for a new pdi intake.

As far as the stuck egr plunger cummins will tell you it is nonserviceable.

Wrong take the valve off remove the back plate and it serviceable it is literally two gears a bicycle chain link and a cam remove the plunger and clean it.

If you don't understand the parts named in this or understand simple mechanical things leave it alone take it to someone who does its not hard to fix but unexpected things do happen.

There are kits available online to make this job a little more friendly to the installer.

If you don't mind the check engine light it's fine. I ran my 06 isx probably close to 500000 miles that way before I did what is described above. Just make sure the engine is cold before you unplug the motor.

I bought the "Ugly EGR Fix" for my '07 KW w/ISX 565. The part was a few hundred dollars, had it shipped to my mechanic who put it in for a few more. Only problem, EGR Cooler started leaking shortly after.

I spoke to the guys at the Ugly, they said to simply remove the EGR cooler...plug it. The mechanic shop I took it to couldn't figure out how to do that. They wanted to sell me a new EGR cooler...I found out why.

I asked them how much the new cooler was going to cost, they said they weren't sure, but around $800-$900 for the part. I found after-market EGR Coolers for $800. I gave them the truck for a week and went on vacation, told them to verify their price before they did anything to the truck, and, if it was going to be over $900, let me know and I'd order the part I found instead. In hindsight, I should have just gotten my part, but, I figured, if they used their part, they stand behind the work, so, even if it was $100 more, it would be worth it.

I have used this shop for a few years. They are expensive, but, they stand behind their work, get it done and give me 30-60 days to pay my bill. So, they were getting most of my business.

I picked the truck up when it was done....they said nothing about the cost of the part. I asked about the total, they said they hadn't calculated it yet but would send the invoice to me.

It took them 30 days to send me a bill. When I got it, they charged me $1,627 JUST for the EGR Cooler part itself. That is $827 more than what they quoted and what I told them I'd be willing to pay.

When I questioned the manager about the excess, he told me they "forgot" to check the price, just ordered the part.

I told them I was only paying $800, which is what we had agreed to originally. It's not my fault they can't do what the customer requested. They should have known the price BEFORE ordering the part, and if $1,627 was the BEST they could do, I told them I could get an after-market for $800.

We went back and forth via email and phone on this.

I wrote them a check for the invoice on April 12th with a note saying it was payment in full for the "adjusted" invoice #. I explained why...they said they'd get back to me. They never did.

They didn't cash the check until June 1st.

Over the summer, I needed some other work done. I called to make an appointment, they said I had to "settle my balance" first. I told them there was nothing to settle. They said they'd get back to me. They never did. I never went back for more service there.

Today, 5 months later, I got a call from a debt collector. I explained the situation. He said that I need to pay the bill. I asked him "Why?" He said "Because you hired them to do a service, this is how they stay in business." I said, "By telling customers it will cost X, doing the work, not saying anything about the increased cost, then waiting 30 days to send a bill for 2X?"

He said "They have to make a profit on the parts".

I asked him, "When you go to the store and buy something, the shelf has a price tag saying $800....when you get to the cash register, are you willing to spend $827 more for it?"

He said "So, you're not going to pay this bill?"

I said "I already have, they already accepted the check."

He said "A judge will make you pay it."

I said, "We'll see about that."

They are located in Cook County - the most LIBERAL county in IL. I don't think the judge is going to side with them.

The name of the shop is Profection Truck Repair at 3300 Manheim Rd in Franklin Park, IL.

I had been doing business there for over 2 years. New management though. Avoid them.

Anyway...I'd be curious to know how to delete the EGR Cooler...is there a video?

Also, there is a sensor now that is looking for the position of the EGR valve and apparently not getting an answer. Does anyone know how to shut that off or otherwise replace the sensor? I am told that sensor is inside the EGR itself. I looked into deleting the EGR from the ECM, but, I saw places that wanted over $3K to do this!

That is a small claims court appearance I would have no problem going to in your situation. Keep us posted if it happens.

I have a ISM in a IH8600. I did follow the previous instructions and unhooked my egr while eng cold and key on not running. Truck now runs great, engine light don't bother me much either. Was wondering about if I welded valve shut and just unhooked valve control rod and plugged it back in wil engine light stay off and it think it's opening and closing valve or does it read the actual position of the valve or just motor moving it??
