    Default normal operating temp.

    does anyone know what the normal operating temp is for the TB with the 4.2? Seems like it's running a bit hot, but I'm not sure. :?:

    Mine looks like around 200 all the time.

    Default RE: normal operating temp.

    That's an interesting question. I'll have to check out what it is when I drive to work later and I'll post back what it was.

    Sometimes we just don't pay attention to something until it goes KAPUT!

    Default RE: normal operating temp.

    Normal operating temp for me is straight up and down, whatever that is. Never gets near the red at all.

    10 Chevy Traverse LT AWD
    02 Chevy Trailblazer LS (110K+ miles - loaded except for 4WD - WRECKED!)
    99 Chevy Cavalier LS (105K+ miles - commuter car)

    Looks like it runs 200-210 deg. I plan to do some searching to locate a normal 190-195 deg thermostat.
