Possible HG problems, Stop Leak, Brownish Foam

[Ryan754]

I'll keep it simple, feel free to ask questions.

I have an F250, 2003 6.0L Diesel.

Past 2.5yrs I've been adding coolant to my radiator, top it off once a month, no biggie. Talked to a guy who says, "Hey! I know! Add Stop Leak!" - went to walmart, bought a can of Stop Leak. 11/28/10 added Stop Leak. Direction stated to pour directly into radiator and let truck idle for 15-30min. I did exactly that. 11/29/10 I drive 4mi, pop my hood out of curiosity and see this:

In case the pic doesn't work, its white/brownish foam and the liquid also seems to be a little muggy, brownish, but still definitely green.

I don't think its likely I blew a HQ FROM putting Stop Leak in there? Maybe? A good flush with some distilled water is all I need? Let me know, thanks.

Bad idea... I wouldn't ever put that stuff in my truck.

probably clogged the oil cooler

Unfortunately hind-sight is 20/20.

I would agree with the above, it may have clogged your oil cooler, and it also may have ruined your EGR cooler. Both of those can cause the HG's to let loose as well.

It's so interesting you guys all say this, because that is the concensus i'm getting from reading other forums, but this guy (Renown mechanic and highly recommended... :s) says there's still no problems with it and I just need to run the truck with the cap off to let the foam out. I don't know what to think... I'll probably try his method and watch it like a hawk and then this weekend maybe do a flush? idk..

Here's my advice:

Atleast flush the coolant (using Ford procedures, might wanna take it to your dealer) and replace it with Cat ELC. Slap a coolant filter on it and see how she runs. If she runs good, run her hard and see if she pukes. If she does, your looking at oil and EGR cooler repairs, atleast. If not, you should be alright.

guys out of his mind.... the oil cooler most likely clogged and then the egr cooler... causing a loss of coolant and then flash boil... and this will turn in to failed headgaskets if its not taken care of soon... not something thats going to burp out...

Just for the record, you were 100% accurate in your analysis.
