I thought the thermostat temperature rating had more to do with the holding the water in the block during the initial heat-up of the motor and how soon the heater would work on a very cold day. I didn’t think the thermostat had all that much to do with normal operating temperatures. It is hard to believe that the thermostat would be closed all of the time during normal operation.

Would a lower temperature thermostat really maintain a continuously lower operating temperature? If it would, then why would anyone want a hotter motor? My way of thinking is that more heat must be a bad thing for things like my gaskets, wiring harness, oil life, and overall engine life.

I am definitely going to ask about getting a lower temperature thermostat, if it would reduce the normal operating temperature of my car.

You feel you love them too much, or you are just too stupid to know any better.
