I know that there are 3 sensors that control the coolant system. Symptoms: the temperature reading on the dash keeps fluxing between 170 ish and 214 and everywhere in between. It overheated and boiled the antifreeze and blew out the weep hole on the radiator cap. The fan only kicks on for literally 1-2 seconds before shutting off. I need to find and replace the sensor that controls that. Any help on finding that sensor would be aweosome

Hi and welcome to FixYa,
Offhand, your described condition indicates a sticking thermostat, that is there is considerable delay before the thermostat opens. It is also possible that there is some restriction wherein the thermostat is not opening completely when the triggering temperature has been reached. As a test and to confirm, you could try temporarily removing the thermostat and operate the engine without one; observe temperature. The side effect of this test is that it would take some time to warm-up the engine, but operationally should not cause anything untoward. Of course, care has to be exercised that the gasket would still be intact.
Good luck and thank you for using FixYa.
SOURCE: Overheating problem
With the sensor unplugged and the fan works,, replace the new sensor,,,,, it is probably defective. I have seeh this before.
