The fans that cool my engine off is not
coming on and my car overheats wat exact
piece do I need for my car not to
Either a fuse that powers the fan relay, the relay that powers the fans, the fan motors, or a fuseable link between the battery and the fan circuit. There other things like a bad temp sensor but I would start with the fuse and relay, then look for the link (it is usually close to the battery and looks like a connector in the cable), and if those are all good, test the fan motors by connecting them to a 12v source directly to see if they come on.
