Thanks, Denny -- I couldn't have said it better myself.

I personally don't believe in either shock cooling *or* shock heating --
but
an awful lot of mechanics do.

So, I treat my engine like it's made out of glass.

"Shock heating" I can understand. When you start your car on a cold morning,
you don't rev the engine to 4000 RPM, do you? Same thing when you start your
airplane's engine; you don't go immediately to full throttle.

Now, spraying cold water onto your engine as soon as you taxi in would be my
idea of "shock cooling".
