On an older car, this would have helped reduce the engine temp by opening the Tstat sooner. Current computer controlled engines determine the mixture needed based on several factors - one being engine temp. FOR is correct. Putting in the lower temp Tstat will confuse it and enrich the mixture to compensate.
