[V8] Radiator Problem

[Kneale Brownson]

That copper pipe in the pix is what I soldered the wire to to make an enlarged area to put the hose clamp behind so the hose wouldn't slide off.    It's 1 3/8 OD copper pipe that's probably called 1 1/4 (the ID).  That's 3.5 cm OD.  I think I had to file the inside of the radiator nipple just enough to remove the water scale to get the copper pipe to slide in.

over an inch in diameter. I would call it a pipe, but it's plastic and 
extends from the radiator body. It is not removable -- it's physically part 
of the plastic radiator.

Radiators made of plastic. Why didn't they just use cardboard or balsa?

Kneale -- how did you solder 10-gauge wire to plastic? By barb, I'm 
assuming this is to keep the hose from slipping off of the shortened pipe. 
Is this absolutely required?
