Crf450R water pump problem.. HELP ME???

[Tippman21892]

when i start my bike right under the water pump thrs a tiny little hole (which i believe is suppost to be there) that coolant starts dripping out of and when i hit the throttle it flows out...then my bike gets really hot. does this mean i need a new water pump??/ :bang:

At least some seals.

Does it also make a nasty griding noise?

Seals,late model impeller w/anti-cavitation hole and bearings all at once.If one of them is gone the rest aren't far behind.

seals for sure...... and a new pump shaft.... the old shaft has a groove in it and if you just do seals you're wasting your time..... :yell:
