I was blowing snow today and my x728 starts overheating. I burped the cooling system to no effect. The radiator is stone cold so I'm suspecting a stuck thermostat. In every other engine I've ever seen the thermostat is located at the return hose that connects at the top of the radiator. This way it senses the water temperature as it exits the engine and reacts accordingly. However, the Kawasaki 750d has the thermostat located at the supply hose from the bottom of the radiator where the cooled water is entering the engine. Does this make sense or am I missing something here?
