Greetings Bill and Allan,

Sorry if I misled you allan, after reviewing the electrical diagram my car is set up differently than yours, and you do happen to have a seperate temp probe that will kick on your aux fan as Bill said. From the looks of it, I think it's the one located on top of your radiator elbow. Looks like a cheap repair if it goes bad, but the aux fan is a different story as far as price. Perhaps a good used one from a salvage yard would work fine and most likely run you less than a quarter of the price. As far as your regular cooling fan assembly goes, is it clutched or not? Just look on the front of the blade housing for a round finned item attached to it, that's the clutch if you have one. From what you said about the blades being able to turn by hand a quarter of a turn, it sounds like something is amiss with your clutch, and if you don't have one, I'd say some bolts are missing out of the mount from fan to water pump. With the engine off a clutched fan should move fully around with a small amount of resistance. The nine bladed flex fan you speak of would provide more cooling effect across the radiator and from what I see for prices, only runs around $36.00 to buy. Perhaps partshop can get this item for you as well.
