Agreed, as far as the previous question about thermostat temp rating, if you have a 160 degree stat, it will initially open and then more than likely never close(hot climates)therefore the coolant is not spending enough quality time with the radiator to transfer the heat from the engine to the atmosphere...get it? got it? good
just as why you never take the T-stat out as some think will help, water runs thru radiator too fast
