Since the water pump turns opposite the normal rotation, so does the fan. Be sure to get a fan that will pull the air through the radiator, not push it. A friend's Chevy Nova 4-cylinder would overheat on the road, but not in traffic. I found that he had installed a Chevy Vega fan that was supposed to turn CCW, and it was stopping the airflow through the radiator at higher engine/road speeds.
