Went out for a ride today and my quad overheated. no coolant leaking and outside temperature was around freezing. My gauge started flashing the temperature picture, I stopped the quad, turned it off and you could hear the coolant bubbling hot. I let it cool down, started down the trail for about 15 min and again gauge started flashing so i turned it off waited for it to cool down, this time I was able to make it to my truck. Once home I checked my coolant level in the rad and i could see coolant up the neck but none in the expansion tank. Looked around the water pump and no coolant leaking , my fan had been working all day but when the bike overheated the fan was not on, could that be the issue? It was a cold day, would it still need the fan? How do I check the water pump? Could that be my issue? Could it be the thermostat?
Thanks
