EGR Cooler Question

[frakchered]

Hey guys, I got my BPD EGR cooler. And plan to swap it out this weekend, being a good sunny weekend here in NC and a three day weekend for the military people.

My question is pretty much for the guys who have done a delete versus a better cooler. If I am not mistaken in my reading, the coolant flows through the cooler from to the oil cooler into the block. I maybe wrong but not important. Here is what I want to know, has anyone noticed a difference or a drop in temperature by deleting the cooler? I would think, without having to cool the exhaust and it goes into the oil cooler, it would help to better cool. I have read numerous posts, but do not remember anyone saying they had a temp drop. If anyone can help I may sell the BPD cooler and delete is as I really do not need it.

Much more important, is the fact that soot/hot gasses are not being dumped into your intake. Will run better, and keep from trashing your oil with soot.

Ok, got another question. We leaving the EGR valve plugged in hurt anything after deleting the cooler and blocking the pipe? It's not in the budget to get a tuner to kill the EGR engine light and wil that even keep the light from coming on?

Leaving the egr plugged in, is recommended. Others have reported the fan not operating correctly with later ecm strategies, when the egr is unplugged. A far as the light, there are mixed reports on that. Idk.

I forgot all about the fan not working sometimes. I have read that before. Got a recommendation for anEGR delete? I was think RCD from Rudy's diesel since they are in western NC and I am on the coast in NC. I have felt with them before and it is 109.00 plus shipping

I think they are all about the same, I think the one you are mentioning may be the one I was looking at. Make sure it is the one piece design, stay away from the two piece design.

I will have to double check, but I think it is a one piece. It also uses a plug for the up pipe instead of replacing it.

Alot of guys like to replace the up pipe on the later models because there is a scoop in there. I dont personally believe it is a big deal. Some guys just pull the pipe out and flatten the scoop.

Well being I am not building a high horsepower engine Inwill prolly not worry about. At this point in the trucks life I have no plans of even running a tune yet.

IPR Research's second generation EGR cooler delete is the only real one-piece design that I know of right now. It's a little more expensive but one less point to leak. I would get rid of the scoop obstruction in the up pipe too (which you have in an '06).
As for temps they will actually go up some because the point of the EGR is to re-introduce exhaust to the combustion chamber and lower combustion temps (and NOx production). But the soot kills the engine and the exhaust gas heat will eventually kill your EGR cooler and coolant.
