... I think the very best alternative is to buy a purpose-made stainless
steel lower radiator hose spring for SBF for all of $5.36. The cost is
minimal and, in this way, you can have a correct-looking lower radiator hose
with the protection and corrosion resistance of a stainless steel part. I
thought I should share this with anyone who is working on their cooling
systems like I am. Here's the link:

I hope this is helpful!
