Toro z master commercial mowers cooling fan won't turn on while running

[Joshua 12123]

Hi I have a Toro z master liquid cooled commercial mower and the fan won't turn on when running it will turn on when the key is in the on position but turns of while running and won't turn back on it had overheated once and I don't want to damage the engine so far I've checked the relays and fuses but nothing has changed it still won't turn on while running I think it's the temperature sensor but I'm not sure where its located and how to replace it

the generic answer is that most radiator temperature sensors are on the bottom of the radiator because that is where the coldest temperature is. Usually that controls the fans blowing on the radiator.
