If you have in writing where they told you to drive it, then do it. Any damage from here is on them

Im actually looking for failure points from the heat ect. Maybe a manifold or something will get warped.... Would not mind a new engine at this point.

 

let's see, if the EGR cooler is leaking then coolant is being spit slowly into your intakes, mixed with soot, gumming up with oil, getting sucked right into the intakes, coating your cylinders, scratching the cylinder walls, and slowly seeping it's way into the engine oil. It's a vicious cycle, I can't believe your dealer told you to just keep driving it. I guess it depends how bad the leak is? Is it very very slow or are you talking a lot every day? When I noticed mine leaking, I had to drive it about a month, I may have lost half a litre, but it seemed to be stablized, I put some in, and it wasn't dropping really fast. Keep an eye, mark with a marker where it was and keep an eye at how much it's dropping. I believe it's best to check it when cold on a level surface and check it consistently at the same temp to get a better idea of how bad it's leaking.

 

You'll probably be a fire truck. Hook to a trailer and take a long trip

It's likely leaking coolant into the exhaust, which will eventually kill the DPF. Just make sure the service ticket indicates you were given the vehicle back and told to drive it, then you're covered.

 

None functional as in shut off via tuning? If so then just take it off and stash it away. But if your running stock tuning then I would stop driving it the leak well only get worse and well likely do permeant damage. Bullet proof diesel makes a egr cooler that looks improved you might be able to have an independent shop replace it with one of those and get reimbursed from fca.

 

Even if the truck is tuned, am I correct in thinking that coolant is still circulating through the EGR cooler and could still be leaking as described by cds13a above?

 

you are correct, coolant is still circulating regardless of a tune. where it would go if egr is tuned off, is the million dollar question... some say it'll go in the exhaust, which is very likely, could it damage the DPF, probably?

I'm not sure if coolant could still make its way up into the intakes with a tune shutting the egr off, so there's little to no pressure of gasses pushing coolant through... I don't know. what's the point in sinking all your $$$$ into a crappy designed egr system that is prone to failure, buy a new one and have to replace it again in a year or two is pointless for crappy designs by FCA. if it's under warantee, do it, if not, up to you...

 

Have it documented like Bounty said , that they told you to keep driving it ...
december , yeah , dec 1st dec. 30th ?? 6 weeks - 10 weeks .....?
risky business...
-------------------------
dodgebrat , EGR cooler can fail in a few different ways ,
if the dealer told you to drive it , then it is not the way the valve gets stuck open and send hot
exhaust gases to intake until it melts the Intake , but it could develop into that ....
as for the coolant leaking inside EGR cooler , it can go to intake manifold , or it can go the the
exhaust portion inside the EGR cooler , both destinations are bad , some have seen
coolant go to cylinder while truck is stopped overnight and on start up the next day ,
( the cylinder being full of coolant ) " hydrolock " on start up , ( hard to turn over because trying
to compress liquid instead of air ) . keep an eye on the coolant bottle , don't let it go lower than
the seem in the middle of the bottle , maybe you have a small leak and can go to december , 6 weeks is
a long time to risk this without looking everyday at coolant bottle so you better monitor everyday .

here is a post by
B-g-K is talking about the inside of his DPF after his EGR cooler was loosing coolant ,
the coolant was going in the filter and clogging it , he gutted DPF to delete after his problems
that's how he could tell us the effects of coolant going to DOC and DPF both locate inside
the DPF canister

initial thread where he started to talk about his egr cooler leaking
and he was getting message in dash about DPF being full and needing
highway driving , but soot % kept climbing way too fast , not normal , as can be seen
if you have a monitor .

Okay, I don't know if it can happen on the EcoDiesel. But in my big truck, the EGR cooler failed. Only I had no idea where all that coolant was going because I had an oil bypass filter system that would burn off the liquids, so it didn't show in the oil. But we finally got it diagnosed and the EGR cooler replaced.

Alas, it was too late. A few months later other stuff began happening to the truck. Had to replace the camshafts and get the head reworked. A couple of months after that we had to get the entire bottom end redone. $40,000 later, there I was. And it was because of the residue from the coolant which does not play well with the oil which then begins to tear up the metals.
