160, 180, or 195*. Which ones the best. I was told the 195 is what the computer was programmed on. I personally like the 160 and 180 better. Which ones the best?

im runnin with a 180 and it made a big difference but ive got a chip tuned for a 180 so i dunno.

i asked the question once. with out having a performance chip in the car there is not benefit to having any other thermostat other then the stock one. A I have heard that will can also cause unnecessary engine ware.

I'm not really sure how a thermostat could cause any engine wear :-?

Without having a chip that tunes your car to run cooler, there is little benefit from a lower temp thermostat. Although with you in Arizona, if your car runs on the warm side of normal anyways, I would throw in a 180 degree thermostat.

About the comment about a lower temperature thermostat...... I have heard that prolonged use of a low temperature thermostat could accelerate wear on the engine. (kinda like how beating on the engine when it hasn't warmed up isn't a very good idea.)

I had a 160 degree thermostat in my 1991 Z24 for about 20,000 miles and a little over a year when it was totaled. When I disassembled the engine, I didn't see any abnormal wear on any of the bearings or the cylinder walls. Granted, I only had it in for 20,000 of the 90,000 miles that are on that engine, but that is my personal experience.

the lower the temp, the colder your engine runs, but also remember this, your heater will be colder because of the thermostat...

Where exactly do you get 160 and 180 degree thermostats? The only ones I can find are at the parts store and they don't say what they are or what they are for.

GM universal sizes, autozone, napa, pepboys, etc.
