The best place is in the head as it will give you the best & most acurate temp reading in the spot that gets the hottest. Most of our cars came with a 180 temp t-stat & back in the day we all used the 160 tamp t-sat because a coolengine is a better running engine. New car enginges run hot for emmisions only , they make them run that way but it is NOT the best thing for the engine.
