EGR Welded Closed

I have a friend of mine that wants to weld his egr closed. I hear this is the same thing as a EGR delete as long as you unplug the egr valve. Is there any kind of write up or anything that shows how to do this or where it needs to be welded at? Thanks!

No it's not the same thing as deleting. You still have coolant going through the cooler, just not the exhaust gasses.

Welding the egr valve is definitely not the same as an egr delete, the hot exhaust gasses will still be getting into the egr cooler because the valve is after the cooler so the egr cooler can still crack and leak.

He can have the cooler welded shut, but, depending on the year of the truck, he will throw codes for lack of "flow" through the EGR valve. Thus needing a tuner to shut off the egr system. Also, I have read where the fan will not work properly with out the EGR system working.

I suggest your friend do a lot more digging!

Might I suggest this link for egr and fan issue.

I agree.

If he is having EGR cooler issues I would check the oil cooler since it is the root cause to EGR coolers failing.
