I have had a run of bad luck on my atv. First the plastic rad fan dried out and changed shape so wouldn’t turn. Electrically would have been fine but I overheated anyways. I changed the entire fan assembly & it seemed I got away with this overheat. Several rides later the thermostat got stuck closed. This caused another overheat Now after changing thermostat pressure builds in the cooling system & forces coolant to overflow. It seems that it “might” be the head gasket ??? I was hoping to source a head gasket & timing belt from a source other than arctic cat since they want $1100.00 for these 2 items !!!! The local dealer also said their are 3 possible head gaskets for my atv ??
