Hello to all, and now a coolant question...

That's because the operating temp is the same regardless of which thermostat is used. As you stated, it just opens at a lower temp, so the coolant starts to circulate sooner.

Actually, is more due the inaccuracy of the factory gauge. On fully instrumented cars, there is a significant difference in both coolant and oil temps.
