    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. :?:

    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!

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

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