Default Re: Cooling System vs Outside Temps

Whether it's 50 or 100 degrees outside the engine block should stay about the same, if you use a thermostat. And, of course, we should all use a thermostat.

It would be interesting though if someone not using a thermostat would shoot the block temp on a cold day and again on a hot day.
