Well for starters there is a FAQ on this. i finally ordered an entire Fan assembly to do this write up and because my fans were hardly spinning. for a Subaru radiator fan I ordered the primary and secondary fans for a Subaru Impreza. These are for 1993-2001 Imprezas     Primary Fan assembly Part Number: 45121FC050   The primary fan has 5 blades     Secondary Fan Assembly Part Number: 73310FC050   The Secondary fan has 7 Blades Both fans and part numbers above only fit the Primary mitsu fan only!
