I searched already so don't get testy! I need to replace me engine coolant sensor because my ccar told me it was not working according to the blinking engine light. where the helll is this thing. i was told it was at the lower left part of the radiator but there isn't sh*t there. If anyone knows where i can get another one of these sensors, where the f--- it is located and how to replaced please edu-ma-cate me. my car starts like crap and i wanna fix it.
