I'm in the market for a new radiator. The one on my 2004 636 was already busted up and jb water welded when i bought the bike and the leaking is really annoying. The bike currently has a 2005-2006 radiator. Supposedly, its a lot beefier, and bigger for better cooling than the stock 2003-2004 radiator's.

My question is...will the 07-08's work properly?

I noticed the 07-08 radiator doesn't have a smaller hose inlet on the right side. So i'm guessing no? Or is it possible?

I didn't see a temp sensor outlet on the 05-06's so I thought they wouldn't work on the 03-04?

I am in the market as well. I am attempting to brace the junk one i have now to make it last the rest of the season but would prefer a replacement.

Better brace any new radiator you get too, or here in a year or two it's gonna be the same thread, with slightly different wording
"well just broke my second radiator"
