I have 2001 sportsman 500 ho.anti freeze is dripping from the center of the bike right above the universal joint. It's very tight and hard to see but it looks like a bolt or plug may be missing from the bottom center of what I beleive is the water pump ? Anyone have any diagrams of this bike or ideas ?

 

May be coming out of the weep hole in the waterpump cover. Is on lower right side of motor.
