What are the benefits of replacing the radiator fan with an electric one?
The CA18DET, just like the KA24DE, comes with a clutch fan that is driven by the crank pulley. Replacing this fan with an electric one removes the drag of the clutch fan from the crank pulley. This results in a small boost in hp but more importantly, it greatly frees up the front of the engine, making the water pump, power steering, ac and crank pulley much easier to work on.
