Serpentined 258 water pumps spin the opposite direction of a vbelt ones. I have heard they are interchangable as far as bolt up. Might be true.

Anything is possible if you don't know what you are talking about.

And YES they look exactly alike.

As fast as you are reporting an overheat even the wrong pump would not cause this. A wrong direction pump would really show up at freeway speeds. On a warm day temps upwards of 220 to 240f are the norm with a wrong pump. Around town at low speeds it would only runs slightly warmer than it should. The only other thing that would be caused by a wrong direction pump is thermostat operation would be weird. I have dealt with 3 wrong way pumps in Jeeps in the last 2 years. They all exhibited the same characteristics as I just described.
