Car is stored presently, but started it last week, got distracted, and it overheated, then dropped all its coolant. There’s a hose going to thermostat housing, then going down from there…I cannot lift the car to be sure, but it feels like it has popped off. Where does it go to? What is it connected to? It would cause all cool and to drop to floor? Is it just a 1/2” or 5/8” hose or something fitted? I’ll be able to get at it in a couple weeks, can’t get pics cuz it’s wedged in tight spot, but making plans now. Was originally fitted with Strombergs, but converted to SU by previous owners. Is 1970 series 2, 4.2 convertible.

 

You are just going to have to lift the car and look closely where the leak is coming from then reattach. The length and shape of the hose should give you a clue. So many hoses on the 4.2 it’s like looking at a bowl of spaghetti. 😊

 

Was hoping to get ahead of it and have a spare hose in hand in case needed.
Coolant was spraying out under some pressure when I got to it to shut car down…I’d wasn’t just draining.
Am also hoping someone might know what it is supposed to be attached to.
Update…. My son just came in saying he crawled under and felt around….it is disconnected, but didn’t feel a clamp around loose end,
but a zip tie. Also that it appeared to come down from above ( thermostat housing, and turn back…not to radiator.
thanx for all replies.

 

Could the hose possibly go to the overflow tank on the firewall? You might have to refill the system with plain water and see where it is leaking maybe with motor off or motor on if the leak is past the thermostat. One reason I like the Moss paper catalog is that it diagrams every part. The hose kit is 16 different hoses…

 

Thanx for the diagram. No, the one to overflow res is #47, and is in place on my car. The hose I’m asking about is not shown here. I’ve looked at dozens of pics and drawings and have yet to find it. I did see a post about an air bleeding hose somewhere, but it was vague…. The post was about filling the cooling system, not specific enough. Mine goes down from thermostat, then torts back, under engine, on opposite side ….passenger,right, side. Overflow is on left,driver side.
There also appears to be a metal tank or something under carbs, towards back of engine that I have no idea what it is….. my thermostat hose may go to it?
sorry for being vague….car is in storage and wedged in pretty tight….. I can barely squeeze in, let alone bend my aging self to get at much. Suppose I’m just going to have to wait till owners of other cars return from sunny south. Thanx.

 

I should mention, previous owner did resto himself, but sadly passed about 6 months ago. So now I have to guess at a lot. Am more driver than mechanic too, but I try
i know it was converted to SU carbs and have a vague memory that that plays into cooling system somehow.
