Trying to revive and Old Mule that's been sitting in a barn untouched for years. Have been through a bunch of stuff, but am stuck on a couple of things.
This is a Polaris Sportsman 500 with a build date of 7-1997 I can provide some additional information if needed. I've tried to open some of the Service Manual links in other threads, but none seem to work.
So far:
Cleaned out stale fuel, unclogged carb, etc. It runs smooth for the most part but backfires quite a bit on reducing throttle.
Had to replace the rodent destroyed clutch/drive belt. Clutch was also frozen to the shaft and would not move, but some PB Blaster and gentle persuasion got the resolved. From that point, we had trouble getting into gear with stalling, but we're now able to do so.
Major issue at the moment:
It will run and drive for 30 minutes or so, then it goes into overheat, red light comes on. That's where it gets interesting. You lose ability to shift gears and cannot steer. Everything seems to lock up, both front and rear. Attempting to drive forward and steer, it pushes the front wheels sideways so you keep going straight and cannot turn. You also can't change gears, or get into neutral to push it.
After it cools for 15 minutes or so, everything works fine again, until it heats up again.
So, WHAT is overheating? And how do I try to resolve it? Are we looking at a transmission fluid issue? I though the red light was engine temperature only. And there IS an issue there since coolant is being pushed out of the overflow bottle onto the ground.
We have other issues that are more minor which I'll go into in the next post, but this overheat problem may make it not worth pursuing if we can't get it resolved. It may just go back in the barn to rot again.
Help me not allow that to happen. Otherwise it in great condition with only 400 miles on the clock.
