Hey guys, so i was towing my dirt bike yesterday about to go riding and i noticed my temp gauge sat on cold the whole time it wouldnt heat up so i popped the hood checked my temp sensor wasnt loose and the engine was extremely hot.
I cranked it back up to see if the fans would come on but they only come on when i turn my AC on.
I have a spare engine so i changed the thermostat and temp sensor but it still does it.
Could it have something to do with my dash cluster being faulty, like the temp gauge isnt working and not telling the ecu thats its too hot and to run the fans, not sure if the temp gauge acts like the rev gauge and vtec.
Anyone have any ideas?

 

Did you ever figure out what pin the temp gauge
