What radiator are you using? Hawks has a kit but I also like the spliced idea that a member did on an LS3 swap into a Bird.

Thanks for the picture. Looks pretty good other than proximity to the power steering pulley. Did you try swapping ends or did it fit better the way you installed?

That splice from "Jags That Run" is used widely by people at this site. If you have a manual transmission then you might want to take a look at what I did because you won't find a cleaner steam line install anywhere on this site. My engine will self purge without any tricks, manual bleeding, or any effort other than adding coolant.

With my luck that will make incidental contact with the pulley. The hose gets pretty heavy when full of coolant, and more flexible when hot. I'd feel better with something that I can strap to the upper radiator shroud.
For reference, my hose is 5" away from the pulley today and is strapped to a support cup built into the fan shroud. I have a dual fan radiator shroud that looks different than yours. It really does look like the hose would fit better if flipped in my case.
