radiator hose spring

I made one for my lower hose that had to make a bend sharp enough that the hose wanted to kink. I use some 5/32 wire that I wrapped around a 1 1/4 bar, and turned slowly in a lathe until I was sure I had enough distance for the hose.
 
Years ago my 40 Ford was running hot at high speed RPM. Setting in my drive and revving the engine, I noticed the lower radiator hose was sucking together. My son inlaw works in a big ship yard and he made me a couple of stainless springs to put on my lower hose. Cooled the engine right down at high rpm. Walt
 
Make one by hand wrapping a piece of brass brazing rod around a piece of pipe. Use a smaller dia. pipe to allow for spring back.
