Well,not year specific,but usually there isn't really any harm in a motor running cooler.However,you won't really see any benefits from a cooler thermo unless you use a manual fan switch or a Hypertech to change your fan settings.But it's not going to hurt anything to install just a thermo.Good luck.

I was woundering about this also. Will this throw a ses light because the engine is running cooler than the computer thinks it should? the only reason that I ask this is I have the manual fan switches and if I leave them on till the car drops below "normal operating temp" it throws a code.Remember that sometimes, silence is the best answer.<br />Warren White<br />1996 PoloGreen Coup <a href=\"http://vampyr.settanni.net/\" target=\"_blank\">http://vampyr.settanni.net/</a> <br />\"Jealousy\"<br /> CTFBA member of the month Sept 03

One of the cons of running cooler is that in the winter (above the mason-dixon line :D ) you want your car to run a little hotter, it actually runs better when it heats up. I live in a southern climate (Mister-Sippi) so i want it as cool as possible. i run a 180 stat in a 3.41993 Camaro 3.4L A4 many mods comin for 2004<br /><br />\"The last thing I wanted was to get in a fight in Jackson, Mississippi on a Saturday night\"

Yes the car will run rich if you have a cooler thermostat. I replaced my themostat a while back cause it was stuck open...have no clue what the shop installed but I usually run at 175 at about 35 on roads, sooo it might be a 160*, but I really have no clue.

You wont run rich with a 160 - the PCM compensates for the temp. The main thing is to keep the heads cool - it prevents knock and increases thermal efficiency. With a 160 stat your temps will be around the 170-180 range crusiing [img]smile.gif[/img]2002 5-spd NBM Camaro
