Although it CAN be that high (cooling fans don't come on until ~230) it shouldn't be that high. Fans don't run over ~25 mph anyway and at 40 there should be more than enough airflow to keep it "down against the stat".
Tell your friend to remove his radiator, clean out all the debris in front of it, and flush the cooling system.

The wire is for the EGR sensor to determine if the EGR is working. Reconnent the wire otherwise he may get a check engine light.
