Coolant leak - can anyone tell me what this valve is for?
Coolant is leaking out this cap.
Coolant was coming out of cap between hose clamps. Looks like the cap is just worn out. Anyone know what this valve is for? Looks like the hose is going behind firewall to heather core.

That;s someone's attempt to fix that hose that has now failed. That hose coming from the heater core is suppose to be one piece.

Thanks for the help. The car ran great all summer. I pulled it out a couple weeks ago, just to start it up and let it run for a min. I went inside and when I came back out the engine was covered in coolant. I'm praying there isn't any damage. It seems to be running fine.

I drained and replaced the coolant. I started it up yesterday and it ran ok, but I wont drive it until roads are clear of salt. I'm pretty sure it ran pretty hot before I could shut it down.
I don't see any leaking oil, any other way to know if it caused any damage?

I would just run it and monitor the coolant level and check the exhaust for heavy white smoke (water vapor). Also check the joints on the engine where the housings meet the plate for oil pooling.
I lent my 1985 to someone that let the engine over heat and they kept driving. Toasted the engine. There was massive clouds of smoke and a lot of oil pooling on the top of the engine.

OP...Agree with checking/replacing the other coolant lines, but I’m not a fan of those worm-gear clamps like in that photo. Good clue that it was aftermarket. If/when you can it’s best (IMO) to use the OEM spring clamps. You can find them in all the various sizes in any U-PULL-it type yard, and from pretty much any Asian import.

Thanks all. Im not positive it overheated. Here is what happened....I pulled it out of the garage and fired it up. Went inside, opened a beer and talked to my neighbor for a few minutes, Looked outside and the engine was off and there was anti-freeze and smoke all over the place. I figured it was toast. Tried to start it up and it wouldn't fire. I changed all fluids, added coolant, new plugs, fresh gas and the thing fired right up. The gas gauge is broken, so I think I got lucky and it ran out of gas before it overheated. As it was running and I was standing there elated, drinking another beer, coolant started flowing out of the broken cap in the pictures. I shut it down and put a new cap on it. It fired right up again and ran perfectly for about 10 minutes. Not under load, just idling. Im really hopeful there isn't any serious damage. It idles and revs just fine.
I ordered the replacement hose, thanks for link. Great site. Anyone know where I can find some touch up paint?
