Well, I got the car tuned, finally, and he lowered the fan temps. I then installed a 160° thermostat to go along with it. The motor is running exceptionally cool right now. On the freeway, it stays at 165°, and while driving through the city, some stop lights, not bad traffic though, it didn't go past 180°. The low fans came on around 160° and the high fans come on at about 195°. Does this sound okay? I heard somewhere that LS1's like to run warm. Thanks

did u autotap it? I know when its hovering a hair over 160 its actually @ 180esk in my car...i wouldnt rely on the factory gauge for my life no matter what year.

I have an aftermarket gauge, and it is dead-on comparing it to AutoTap. The motor is running cold enough to make the stock gauge read a little cooler as well.

dunno what to tell ya...even with my 160 tstat i usually hover between 175-190 in city driving and 170-180 highway

FWIW they are more efficient when warm, but you dont want to run 225 degree at the track with heads/cam so i wouldnt worry about it.

Thats what the guy said. With the timing he put in, running hot = detonation

Anyone else?

um, i would adjust that low fan temp to come on in the 170's i feel like my car runs best 175-180 but doesnt stay near that in this heat we are having now here in charlotte
