T stat
looking at replacing the stock thermostat in my 01. Looking at the 165 degree unit. How much of a decrease in operating temperature does this yield. My car is stock,and runs about 199 on coolant and around 208 for oil
Thanks Guys

If you change the TStat to 165, you will need to tune the car for the fans to come on at that temp as well, or it wouldn't matter much, at least in the Summer time.
Without a tune it will run cooler in the Winter.

I've been told that is too cold and you should leave it alone.

The car came with a 195 tstat. It was designed to run in the 200-225 range. But if you really want 180 you will need a 165 tstat and fan changes.
