Just made up a template out of cardboard for the radiator top metal pipe to be bent up next week , does this look to be correct . Dale

Hi Dale, can get a pic tomorrow of the correct pipes. Also remember the top left and right front corners of the metal surround of the rad are bent and angle forward to take the 2 x radiator stay rods.( there should already be a 5/16 hole there) Your rad has probably come straight out of a cmp, truck without this mod. Also the overflow tube has to be shortened with a joiner union put in the line to take the pipe to the rad overflow bypass valve. Cheers Andrew

I think you mean pressure valve, Andrew?

[Dale Jordan]

Your good Andrew , you don't miss a trick , thank's for the heads up and a photo of the pipes will be great , yes my radiator has those Tabs with the holes , I'll bend them forward . I'll add the pipe and joiner union . What can I do if I can't find a pressure value can I just run the pipe out to the hole in the pannier floor will that work ? Dale

This is what the rad pipes should look like.

You should be able to find a pressure valve. (try an add here on MLU?)
The part number is; 553 - Assembly, pressure valve radiator overflow.
As the thing indicates, it is what causes the pressure in the cooling system. They are adjusted (I think) to 3 1/2 psi (adjustable?) Some (later?) radiators are fitted with the correct neck for a 4 lb pressure cap, but yours looks to be the plain blanking cap.
Raising the pressure raises the boiling point of the water 4 degrees F. per pound of pressure, so a 3.5 pound cap raises the boiling point 14 degrees F. (at sea level) This is a good thing. In fact I'd say very important for a reliable carrier in the potential temps you might want to operate your carrier in.

Hi Dale, Euan is right on with his picture of the pipes. The only thing is that you will struggle to get them to look like this in todays manufacturing, back then they would have had some form of mandrel pulled through the pipe to form the bend, that's my guess. I have "hot dip" galvanized mine , to stop any internal corrosion, even though I am running anti-freeze. The pressure valve is also shown and rad. stay rods. If you need one you know how to contact me, Cheers Andrew.
