I just bought a 1995 Scrambler 400 4x4 with a flywheel that lost a magnet, and damaged the stator of course. After I started checking out everything else, I discovered there is NO coolant in the system at all.


This recently had the top end rebuilt, so I'm thinking it wasn't done properly, and there is a major coolant leak, but of course, I can't locate the leak without it running since I don't have a coolant pressure tester.

My questions are;
What are the chances that this coolant leak was in fact from an improper rebuild, and if so, other than major over heating, are there other things I need to look for?

Could it being out of coolant have had anything to do with the flywheel losing it's magnet, such as a sudden seizure, I guess???

Thanks so much for any suggestions.
