How much horsepower does an electric fan add?

So essentially the electric fans take 1/2 horsepower. The mechanical to electrical conversion in the alternator to drive the electric fan is not 100% efficient, so the engine will have to make slightly more power to provide the electric fan the same horsepower.

Should electric fans push or pull?

Use an electric fan. Preference should be given to a “pull” vs. a “push” fan. Mounted on the engine side of the radiator, a pull fan does not interfere with airflow at highway speeds. All shrouded fans should be on the engine side of the radiator.
