I can't tell you degrees, but I can tell you what it did for me. I have a 2004 WR 450 I bought brand new. While riding around with my kids on their 50's back then, my bike would over heat to the point coolant would overflow. I think it was due to lack of air flow. I put this pump on and have never overheated since. I'm sold it does what it says. It also helps if you're just idling your bike while working on it, or something like that. I haven't noticed the bike running any different, it just doesn't overheat. Hope this helps...
