just replaced the water pump and forgot how it come off. Can anybody tell me the correct position direction of air flow. Blowing toward the radiator OR pulling air through the Radiator. thanks
Is this an electric fan? If it's a typical fan blade that's engine driven then the engine rotation will determine the direction of airflow. Put the fan back on so that the convex side of the blade (outside of the curve) faces the direction the air is coming from, and the concave side of the blade (inside of the curve) faces the direction that the air is blowing. It will blow the same direction if it's on backwards, but won't move as much air and might overheat.
