Lowest temp stock thermostat. Hot climates or original summer fitment with 82 degrees for winter the ideal temperature commensurate with optimum power output is 65-70 degrees. However this is not practical for road applications.The lowest thermostat available is 74 degrees and should be the lowest one considered--82 degrees is a much better choice with an 88 degree alternative for winter driving and those with economy as the main consideration . The higher temperature the more thermally efficient the engine becomes. It is possible to run thermostats with the troublesome by pass hose blanked off by drilling 4-6 holes 1/8" in size around the priphery of the thermostat.
