if you have an 06, follow the big hose going in front of your driver side valve cover. From there you will find a metal cover with a different big hose connected to that. That metal cover is your thermostat housing. Hope that helps. Nick
When I went to AZ it showed that the stock thermostat was a 180. the guy told me that its sometime called a 192 because that is when it is wide open.
now I don't know who to believe.......lol
i dunno but, mine at full operating temp is in the 194-197 range which I always thought was kinda high but alot of guys on here have said theirs run that high too....
changed the T-stat. Mine had 180 stamped into it. I repaced it with 160. At cooler temps the car seems a little more "crisp" but then again it may be just wishful thinking..........lol.
All I know from everything I've ever heard was a motor runs better at lower temps. I can't guarantee that for a fact. THe cooler my car is the better it runs, so I can't answer for anyone else. Also if it doesn't get as hot, then it takes less time to cool off.
If you want a more in depth answer it will have to come from one of the smarter guys here..........lol
