Hi, I have a 1998 Polaris Sportsman 400 liquid cooled, 2 cycle quad. Its been a great quad and runs great. Recently I had it on a good ride and hit some heavy mud spots. After getting it cleaned up and put new fluids in it, I realized it had a small amount of anti-freeze seeping from the lower right side on the case near the water pump. The hole looked like a bleeder type of hole that was made in the case. It quit doing it after riding it for a little bit but just concerned what that was or if it would get worse. Any suggestions?
