Brent, Do you have a fan shroud? If you feel like you get to a point where you need to cool down, don't just shut it off; it can continue to heat and maybe sieze. Pull over, open the hood and rev lightly. Without the engine under load, the fan will pull in air. - Jim Jim Altemose, Long Island, NY '63 Polara 500 (Max Wedge), '65 Belvedere I (Street Wedge), '71 Bronco
