Hey, I have a 72 440 in my 86W-150. Recently changed cooling system from stock rad and electric pusher fan(that never worked very well) to a griffin rad and a 6 blade flex fan. Cooling is much better! Problem fan and power steering pump run out is around 3/8 of an inch. This seems abit much to me, but I don't know. Can anybody tell me what it should be? Last thing I need to happen is it coming apart and sending that fan through my new rad! Water pump doesn't leak so normal or do I need to change for a new water pump? Thankx:yikes:
