No one has been able to prove or show documentation about this.

I keep looking because mine is unplugged. Personally, mine runs a lot better with it unplugged so I would love to see more info on this and not just what people have heard or read.

 

the only thing it would cause is a lot higher engine temperatures at cruising speeds. but without an input to the PCM it has to re learn a new stratigy. its a little rougher on somethings and i dont really recommend it but people do it.

 

how does deleting the egr cause higher engine temps?.

 

A very good diesel shop I trust and have had much 6.0 luck with recomended against "just disconnecting."

 

Could you expand on your answer for us? I would like to hear more...if you don't mind.

Thanks!

 

Mhays,

So do they recommend deleting it all together? Explain

 

EGR activates and opens during cruising speeds to recirculate exhaust air into the intake system. because the exhaust gas cant burn twice it makes the whole engine run cooler. also if you had a delete done then you should get worse gas mileage during cruising speeds because it burns more fuel rather then recirculating exhaust gas. if you ask me... more heat can cause other components to fail in the engine or related systems.

 

I have heard the same thing from several other techs. I will not unplug OR delete my EGR valve until I also install a tuner that will take this into account.

 

In my case......the best thing to do is to delete the egr cooler all together, yet keep the egr valve functional?

I thought with a egr cooler delete kit, the egr no longer has exhaust flowing to it? Am I incorrect?

 

I will agree with less mpg at cruse. With full egr delete I hope tunes will fix that. But what are you to do when every time you try to tow your camper the truck over heats and ford cant fix it. The full egr delete is the only option or maybe I should just not tow at all. I need a truck not a car.

Maybe I am dumb, this does not make sense.

 

I recommend leaving the EGR in place, leaving the EGR plugged in. I blocked mine at the in-take of the EGR cooler along with the up-pipe.
I have noticed that my coolant temps stay in the NORMAL range, before the EGR blocking I have almost hit the RED on my Coolant Gauge several times.
I have noticed that my Coolant fan does not run very often, only under extreme loads, before it ran loud and often under normal loads.
Mileage has increased slightly because of removing the restriction in the Turbo up-pipe blocking 50% of the right exhaust manifold.
Turbo Spools up much faster.
Turbo boost has decreased because the Turbo is not working as hard (32PSI is max)
EGT's went way down to 350 idol and 600-700 at 70 MPH with a maximum of 1200-1300 WOT, and I am tuned.
Another benefit to reducing temps is a full 4" Turbo back exhaust.

 

Thanks! That clears up some stuff for me. One more thing...do you know if the vanes get locked into one position when you unplug the EGR?

 

hangon2me,

I am going to do a full EGR cooler delete. I need to get rid of the POS system. I am sooooo tired of having to constantly monitor my temperature gauge HOPING it will not hit above 212* while towing. Before you say it....my truck already had headgaskets done once...they r good.

So your saying leave the EGR FUNCTIONAL AND IN PLACE?????

I thought when the EGR Cooler delete was done, it blocked exhaust flow to the EGR? Never been into one of these motors so I do not know....Can you enlighten me please?

Thanks
