Default Re: Bending Overflow Tube

Leave the overflow tube as it is and do this instead. It is an orifice made from a stainless steel 1/4" diameter bolt. The hole drilled through the bolt is 0.125" diameter. Insert the bolt into the overflow tube. The radiator cap needs to be a leakless fit. Both of my Model "A" cars have this orifice, and it works really well.
