egr cooler question
Is there a substantial engine cooling benefit to leaving the egr cooler in place and connected, while blocking off egr?
Currently I have the sinister egr delete but am considering reinstalling just the egr cooler for:
1)visual inspection and
2)supplemental engine cooling for towing and such.
Any thoughts?

I doubt having the EGR cooler installed, but stealth deleted has any impact on cooling.
It is theoritically functioning as an additonal "radiator", but again the impact it would have would be next to none.
I did the stealth delete on mine for the added benefit of any visual inpsections that may or may not be coming to my area.
I also liked having the up-pipe being supported by the old EGR connection as well.

Is there a particular "CAT" ELC I should look for. As I understand it, CAT ELC is simply a non-silicate form of extended life coolant, right?
I'm sure there are good formulas and bad ones, as I would assume is true for brand options as well. Is this correct?
Is it a comparable cost with Ford Gold or significantly more expensive?
Any specific recommendations on brand or formulas to look for?

I'd put it back on there, Tim. Our emissions testing isn't gonna go away, and if/when the standard gets revised to read live data during testing it's not gonna be possible to pass without a functioning EGR system. I'm sure that's a ways down the road, but I have no doubt it's coming.
If you're concerned about the cooler going bad, you might want to look into replacing your stock unit with the Bullet Proof cooler.
Just my .02, for what it's worth

I know, Steve. It's an option I should be considering as well. I just REALLY HATE that valve, though. Just the thought that it is running carbon back into my intake bothers me. I have to remember though that if/when Cali mandatory testing becomes a reality, I'll have to tear it open again... Hmph.
I think I'm kind of choosing to be in denial of that right now, but it's in the back of my mind. For the time being I'm researching only getting through the visual inspection at this opportune time. When I actually pull the plug on the job, it may entail reinstalling that damned WART.
The only reason I'm looking at doing anything in there at all is because I have discovered that I have a cracked head (small amounts of diesel in coolant) so I was going to install ARPs, upgraded dummy plugs, stand pipes and STC fitting while it's apart. I thought that maybe putting the cooler back in for visual inspection while things are apart would be a good idea... Functioning egr might be something I should consider, I suppose.
Thanks for the advise, unpleasant as it may be...

When you did the stealth delete, did you set it up where coolant is flowing through the cooler or is it ONLY for visual appearance? From what I'm hearing here, I can see where NOT connecting coolant flow to it may be a better option so you don't have to worry about a leak in (or at) the cooler. That is assuming that the benefit of additional cooling is nominal and not worth the risk of a leak.

The odds of the coolant breaching into the old exhaust side of the cooler has to be slim to none and even if it did, it becomes a large water pipe really.
And the odds of coolant then breaching that has to be even smaller.

I still have coolant flowing thru mine. I also did the mod on a good cooler and not one that had been compromised.

So, did you have to use the old up pipe? 6.0techwannabe mentioned to use the straight up pipe, I assume like the one that came in my sinister delete. Sorry if I sound ignorant... But I am. At least with regard the 6.0 engine. I don't work on this thing, just pay through the nose to have things done. Got too many projects going to take on that monster.
Got too many projects going to take on that monster.It may or may not be an issue, but I like having the stock cooler installed and having the stock up-pipe still bolted to it for support.

I remember when Cheezit did his test on EGR plugged in vs unplugged, where there were problems with cooling fan operation. Would turning off the EGR cause any fan operation problems?
Also, would the EGR being turned off cause any carbon buildup on the EGR valve, to where it could cause problems, i.e. boost etc?
ON EDIT Yahiko, I just spoke with a Ford Diesel mechanic and asked him about your idea. He believes that this idea could cause a lot of soot buildup in the EGR cooler and valve. I don't know much about the EGR valve operation except that it opens and closes on demand. This guy told me that there is a bipass that will allow exhaust (and soot) to enter the EGR cooler, which would require removal and cleaning of the cooler if you wanted to put it back in service for a smog test. The valve would be easy enough to remove and clean but the cooler is a different story.
Does anyone have input on this?

If there is no air (exhaust) flow through the EGR cooler/valve, I don't see how soot buildup could even begin to be an issue. If the valve isn't opening, there's not going to be any flow through the cooler. FWIW, I've been running for over 50k with the exact setup Yahiko has planned. No issues at all, and it passed emissions testing just last month.
