I have a 2008 polaris sportsman 500 that just started losing coolant. It leaks from down around my water pump. Thought it might have been the seal until I unbolted the water pump and the one bolt more toward the middle (im guessing a drain plug) and coolant started rushing out of it. Which ruined my thought that seal was leaking out the bottom because if that were the case I wouldnt have had a waterfall coming out of that plug. With that being said there is a hole off the side toward the bottom of the pump and it is leaking slightly out of there. Can anyone tell me what that is and why its leaking? Also more down in the center of the block (crankcase) I have a gasket. Looks kinda beat up in two spots. Im not sure if fluids just streaming out of that hole and gathering in those two spots to drip from or if there is coolant in there and I have to split the case. It seems to me that there is no coolant in there and there should just be oil. Sorry bout the 3 page novel im working on but I want to go ride it tomorrow so any help would be appreciated!

 

not sure, but it sounds like it's leaking out the weep hole in the water pump.

 

Yes but why is it coming out of that weep hole? And am I correct in saying that the bottom of the crank case holds the dry sump area for oil and no coolant goes through there? There is no coolant in my oil so I am pretty sure that it is not in there.

 

if water is coming out of hte weep hole then the waterpump seals are going bad or you have a loose bolt/nut aound the water pump

 

I bought the gasket for it but when I took out the plug toward the middle and all that coolant came out I figured it wasnt it. What other seals are in there?

 

i think he's talking about that burp plug

 

When they leak from weep hole you need a new water pump.

 

You don't necessarily need a new water pump but the seal is going. When the seal fails it allows coolant to leak out(the weep hole). You may only need to replace. Depending on the year of the machine it can be a chore...
