Someone on here should know this. I need to know where the coolant temp sensor is on a 4.3 motor; swapping one out tomarrow cause it threw a code. It's a '94 s10 if it matters somehow.
I dont remember what code came up; but the book that comes wih my obdI scanner for gm's said coolant temp sensor. Like I said, his gauge doesn't work at all, so I'm just going to replace both sensors so I know their good.What code did you have
