does anybody know the stock thermostat rating? im thinkin its 195 degrees. im going to burn a new chip and i need to know so i can base my fan settings on it. thanks

It may vary with year; IIRC my 97 was 195.

stock is 180, you can not get the motor to stay that cool though. Going to want fan temps to be more like 195 or so.

If you have a datalogger go out and see what the temp runs on the highway and then set it so the kick off temp is higher than the cruise temp otherwise the fans will just run whenever the car is warm.

ok sounds like a good idea if i make a another street chip, but i am making a track chip, and i am thinking i will set it at about 175, that way it will run as cool as possible, and it isnt a huge deal that it runs all the time, sound ok? im gonna swap chips when i get to the track, and swap again to get home

Stock is 180. You dont really wanna go 160, 160 is way too cold for any setup. 195s are out there for people who wanna run a lil hotter. I set my fans @ 180 because thats what my car runs best @.

Wow you better go tell all the people sucessfully running 160s that they are not actually working. I think the issue here is your ignorance, you do not understand that an LT1 with 160 stat runs similar cylinder temps to a gen 1 with 180 stat. That said, I think people place too much emphisis on the 160 and a 180 can work just fine, but a 160 causes no "too cold" problems. On a gen 1 I would say a 160 is too cold but this is not a gen 1.

If you have a 180 stat and fans set at 180 you are needlessly abusing the fans as like I said above go cruise oin the highway and see what the temp runs at, the fans can not cool it below that.

My car runs around 180-185 with a 160 thermostat, stock radiaitor, electric water pump.

I have a 160 thermostat and only one fan hooked up and it runs at 170 never hotter then 180.

Where are you guys getting the temp info from?
I only trust the pcm.
I see 175 or so with the 160 and near 195 with the 180.

^True. I was going by my factory gauge.

this is a very good theory by the way, but i just remembered that i can set a high and low speed fan setting, so i can set the low speed at a low temp, and then make the high speed just the stock fan setting

what is haven a 160 thermostat on doing besides keeping the motor cooler. Im getting 270miles per tank and car has power so what else is it doing.

I run at 190ish, haven't had a problem. I put in a Manual Fan Switch, just remember to turn it on if you go that way.

160 tstat increases volumetric efficiency as well as allows your car to run more timing.
