Have a 2001 polaris sportsman 500 4x4 atv and when I put coolant in the radiator it starts leaking from the exhaust. The valves are sealed but it stopped making compression. Do I need to just replace the head? I just rebuilt the hole top end and this is the only thing +valves that I have not replaced and was wondering if that is why it's not starting up. Need answers please.

I recently purchased a 2000 polaris xplorer 400 4x4. When I bought it the starter was bad, speedometer didn't work, and it had been sitting for 5 years. I replaced the battery, and starter. Changed all fluids, and got it running correctly. Then replaced the speedometer in an attempt to make sure the awd would be available when needed. And took it out for a couple hour ride with a buddy.
It ran great that ride with no serious problems just a little carb issues which I was able to take care of on the trails. Then a couple days later I decided to take it out for a ride by myself, again ran great no issues other than a couple times it seemed to cough and then take off again. That day when I was loading it I noticed coolant dripping onto the trailer and the overflow bottle was empty.
Got home and decided to drain the counter balancer, when I did that I got about 3 cups of coolant. Im guessing that it needs new seals and all for the water pump.
My question is how difficult is it to do the water pump and should I attempt it or should I send it down the road to the polaris dealership to get it done?

posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
-fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
-along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
-I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
-can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
-it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
-I THINK it has a mikuni model x carb - diaphragm is ID 26mm OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
-last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
-any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law
