What is the best way to install the hose nipple in bottom radiator hose for a good seal?Does it matter if you use front or rear hole on head for the top water cut-off valve?I printed off a copy of the 40 heater features and installation that is on the web site.
 
I use an "ARCH PUNCH" to make the hole in the hose slipped over a 1 1/2" diam. round piece of wood held tightly in a vice.Makes a nice round hole.Trying to drill a hole in rubber dont hack it,or any other way that ive tried.I'll measure the size of it later,its not handy right now. ken ct.
 
If you don't have a proper punch, a piece of 3/8" water pipe beveled to a sharp edge will do the trick. yes, 3/8". remember water pipe is measure on the inside diameter so the outside will allow a tight fit for the valve nipple.
Use a little Indian Head Shellac available at any NAPA.
It doesn't matter which hole you use in the right head. Factory was the front hole...

I've also used the water pipe method however; I put a split wooden 2x4 inside the hose so as not to tear the inside of the hose once the hole is cut. Indian Head Shellac is a good idea although I've never used any sealant and never had a leak. I also use the rear hole in the passenger side head, to install the shut off valve, the forward hole is for the temp. sending unit.

Actually there should only be ONE hole in the right cylinder head and that should be facing forward. Without a heater, that hole received a hexagon head - brass plug.
If you have two holes, you have incorrect head(s). Also, if you have two holes, the valve goes towards the front. The hose was meant to wrap around the front of the manifold / carburetor base, NOT behind it.
On a 40, there was only ONE water temperature sending unit and that was installed in the left head.

Actually, I was describing the method I use to punch a hole in the lower hose, and was referring to the set up in our '47 (should have made that distinction) in my description, as I had removed the hot water heater that was in our '39 (equipped with an 81A head on the passenger side, with the water outlet shut off valve in the rear and the plug in the front).
