Blueeyes, many of the gen3 V6s were hydraulically driven.
I agree with Willy...wait until it gives before you switch over to electric should you want to. Some pros: less parasitic lost (though I'm thinking the fan only comes on when needed, but still, there is the part that still is attached to the motor). Cons: expense.
There is more pros and cons, but do a small search as Will has suggested.
