Coming home yesterday there was a lot of traffic on the highway and it took me 2hrs to get home... Along the way my car started to overheat so I turned on the heater. Helped a little bit then even at highway speeds it started to climb and the vents were blowing cold air now.

I managed to get it home and when I popped the good I was greeted by a lovely mess that looks like diarrhea.

I've hosed everything off, filled the reservoir, and either I have a plug somewhere (probably where the pair released) or the water pump is dead. When I started the car this morning I had no fluid leaking anywhere, but it seemed there was no pressure in the coolant system and the radiator hose stayed cold. Ideas on where the system let go? I can't get in there die to space and no lift. I do plan on taking it to a shop to have the coolant system flushed - I pray I didn't do too much damage.

Thanks guys for anything you can provide.

So, I found where it decided to let go. Drivers heater core line came off.

Theoretically, even with the line off it should have pressure from the pump to move the coolant and it should come out that line right?

When you have no coolant in the system, the pump will mix air only.
Hard to touch it on pictures, but the stains I see don't look like coolant to me.
Inspect it again very carefully.

So I pulled the duovalve apart as well to check the other end of the heater core line, found the same gunk.

OK
I hesitate to bring bad news, but pull sample of your ATF.

What you see is the result of not properly flushing the engine coolant system---correctly flush the system and you will have many miles of proper engine coolant temp!!

PS: you have been misinformed about the residual heat pump--that does not push air when required it pumps coolant--be watchful of spammers who are looking for post count!!

Blutoe - you're off-base...

What the "fear" is here - it is possible that internal radiator failure might have caused a mix of tranny fluid and coolant.

That is why KJ1 has strongly suggested looking at the tranny fluid - if the tranny fluid has been contaminated this would be MORE MAJOR than coolant system at this point

If that was the case the OP would have reported all sorts of shifting issues, and none was reported, the BW spammer was simply introducing misinformed fear.

All this misinformation can be quickly cleared up by having the OP look at his dipstick!!

the trans does not have a dipstick.

How could "keyboard mechanic" know something like this?
We did not hear form TS for days. I hope he had the issue sorted.
