I need the name of a part or a part number or a place to look it up!
There's a hose leaking coolant, can't tell why because it's pretty much hidden. It is, however, the hose that comes off the thermostat.

I can't see it because it goes under the carburetor heat shield and I'm kinda scared to remove the carburetor --at least until I have the part.

There are pictures in my Service manual that show the hose leaving the thermostat but I can't tell what it hooks into under that heat shield--maybe a heater inlet or outlet hose? And yes, I can take a picture but you can't see anything beyond a hose leaving the thermostat housing.

One off-the-street adviser told me where it went but with a flashlight, he was wrong; the other thing he said was that it had a metal or hard plastic connector on the unseen end but you know about his credibility.

Oh, and any wisdom on places that might carry a part that will work since I've no real hope the part itself is around anymore.

Thanks much, Saralou
