Sorry to hear that man, I wonder what would have caused that to happen? seem to me like it would have happened while the truck was on / driving. not while parked...

That would be my guess as well, not sure as to the how, no crazy driving, no off-roading just an up and down the HWY...

Trying to talk myself off a ledge...

FYI- You can bypass it at the firewall until whenever.

Sucks. And I feel for you. Itís a time consuming job to fix.

Iím not advocating stop-leak in any way shape or form.....but.....it is an option to try. A bandaid at best, with possible consequences....but....it is an option. Choose wisely.

Iím surprised as hell it happened to a 2010! :-(

Why doesnít anyone ever ask for the least aggressive mud tire? ~jsexton

@MeHere! I did some google foo and came up with this tidbit about putting stop-leak through the core. Itís actually pretty damn smart, keeps it out of the radiator and hoses.
(If mine ever leaks Iím doing this first.)

https://www.thenewx.org/forum/11-pow...-dash-out.html

I put ďheater core site:thenewx.orgĒ into google. Many more hits. Didnít see any direct how-toís in my quick gloss over, but Iím sure there are several on tearing the dash apart. Thatís the gist of it really.... lots and lots of tear-down.

I think I'll go with the bypass for now, is this only an issue when I run the heat or is it going to leak regardless?

I am now trying to turn this into a positive...I have a new air horn, a back up cam and a volt meter I want to hook up...

I'll do the bypass, get everything else ready and just make a big weekend outta it

It’s an open loop. It’ll leak if pressurized. Meaning, yes, it’ll always leak.
Bypassing it eliminates the pass-through of coolant, thereby the leak.

Give some thought to the localized stop-leak fix. I bet it’ll work. And much much less headache than tearing into the whole dash. (Just my 2 pennies.)

No matter your choice of fix, I wish you the best.
Don’t let this kill your dreams. Parts fail. It’s their job to do that. Regardless of make or model! The Disco I had a few years ago was constantly giving me fits, but man, did I love it. And I love the X even more!

I have read some good reviews on Fiber Lock, I may do some more research on that brand

I am now way back from the ledge...my wife's voice "how mcuh?" was pushing me, lol

I still love my X
