I have the electric fan mounted onto the fan shroud , no fan on the waterpump . The fan is controlled by an adjustable temerature switch so hopefully it will turn off at highway speeds and on at slower speeds . I'm sure a new radiator with the proper cap would solve my problems , I just need to sell some stuff to make some cash . Anyone have any experiance with the aluminum ones on e-bay - going for less than $300.00 ? I know they don't look just right like a stocker would I'm not too concerned with originality .
