What size hose is this? (1 Viewer)

[Mr. Toad]

My '75 2F has a hard coolant pipe mounted horizontally on the head on the passenger side just above the distributor. A soft hose goes from the back of the hard pipe to the heater inlet on the firewall. A standard 5/8" ID heater hose fits those fittings.

The front of the hard line connects to the small metal inlet on the hose at the bottom of the radiator. 5/8" ID hose is too big, and 1/2" ID is too small. Does anyone know what size hose to use here? Or are these joints made of unobfittium?

Thanks in advance,
Shawn

Always used 5/8."

It is very possible that over the years, corrosion has caused enough material to be removed so that a 5/8" heater hose will not seal on it any loger....been there.


Replace lower metal tube piece. Early trucks this was a fitting that could be replaced, later trucks, this was a one-piece affair...


Good luck!

Sounds reasonable fellas. The lower fitting is replaceable. I'll give it a try. Thanks again.
