Today my 2016 Evo 200 puked its coolant and overheated. I was able to take some water from my backpack bladder and get enough in the bike to finish the loop and get back to the clubhouse/car. Now that the bike is home I'd like to figure this out and wondering what order to test things out. I'm learning to be mechanically inclined for sure, though my wife will not be happy if you all tell me I need to buy an IR thermometer or something! I'm thinking I should start with the easy stuff and then proceed to more difficult stuff. So fan, fan switch, thermostat, water pump in that order. I put new automotive coolant in it (1/2 distilled water, 1/2 coolant) just now so that I don't waste my new expensive bottle of Engine Ice if it pukes itself again. I warmed the bike up and the radiator seems quite hot, slight smell of coolant but not really any I can see dripping or steaming anywhere. The fan does not go on at all. One of my friends suggested jumping the fan switch while the bike is running to see but I've got no clue how to do that. Any other thoughts on why my bike is using coolant or decided to overflow? It hasn't been abused and there is no mud anywhere on it nor blocking the radiator.
