160 F Thermostat vs 195 F
Which is better? I have the 160 and my car really doesn't run like it use to. My temp use to always stay above 200 now I can hardly get above 180. I'm switching back to 195. Its been real cold here in l.a lately.

Run the 180 or 195. The 160 T-Stats are for race cars, or summer only cars that aren't used as daily drivers.

I'm running a 180 but thinking of going back to 195 myself. I dont see any gains running 180 , it was more peace of mind not overheating, I think with the fan cutting in at 220 the wider temp range between stat and fan is not a good thing either.

Yeah 195 is the way to go. I remember when I had it in there and it ran way better. And let me tell you these 3.1s love running hot and they run great too. Ive never had overheating problems ever. I even installed a fan toggle switch just incase.

A lower stat is not going to prevent overheating. It will lower the operating temp if all components are in good OE condition.
