Okay, I`ve seen that just about everyone has a 180 Thermostat in their car. Why is this? I thought these cars came stock with a 195. Right? Any info for this `newbie` will be greatly appreciated...

car runs cooler with 180 stat but................my car, a 96 ssei also, was running too cool for the cold weather. had to put 195 back in. ill put 180 back in for the summer. my temp was bouncing between 160 and 180 in colder weather.

Primarily the 180 stat helps keep the temp levels down in the 3800'* with plastic upper intake manifolds

180'* are good for modded SC'd 3800s for cooling purposes...put it this way, my aluminum L47 Northstar has a plastic manifold and runs with a 180 t-stat -stock

For supercharged cars keeping it cooler means denser air and more power, hard to use in the winter but great in the summer.

cooler=mo hp less wear!!

But don't be fooled 'gfish777'. The car will still get up to 200* or over if you sit in traffic, especially in the summer. That does't mean the 180 isn't working. That'* a common misconception.
