so i was planing on doing this, but as stated in previous post, it said it could effect my mpg if i lived in a cold climate? I live in Montana and it is pretty cold here from Nov-Feb. anywhere from -20 to 40 during those months
Most people don't experience issues. Only way to know is to try it and if your mpg decreases switch back to the stock tstat. Another option (sort of an in between) is to drill one or two 1/8" holes in the stock thermostat, to allow sort of a small leak through the thermostat, even when closed, and it will reduce the temp slightly. Also helps to prevent sticking tstat problems if they ever occur.
