How hot is HOT

Ford v10 (v8,v6) when water temp reaches a certain temp, half of the cylinders shut down into limp. What is the actual temp in degrees that this occurs?

    At what point does the gauge begin to move above the virtually stationary 'normal' position?

    I have only seen my gauge move slightly above normal 'stationary' position a few times. Goes right back down when I slightly reduce power.

    Blog on trans temp vs the gauge.
  • Currently not a problem, just watching the scan gauge and wondering what temp action should be taken.
  • At those temps your flirting with warped heads and blown head gaskets.
    Don't be worried about limp mode, worry about keeping the temps down what ever you have to do.
    Sometimes you have to pull over and stop if you cannot keep temps in check.
  • Don't know the actual number, but have experienced it. Don't wait it to happen again.
  • I don't know but I believe it should be close to 265F maybe a bit more.
