Yes it is longer, about 6" , will get a pic today for you if it helps, The C59A are good blocks, the hotrodders like them because they can bore them out to 3 and 5/16th without breaking through the cylinder walls, I think I have even heard of them going out to 3 and 3/8th if the blocks will take it. I think they date from about 1947 onwards .Cheers Andrew

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

[Andrew Rowe]

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.
