It was 70 degrees today in Maryland. Took the '67 covertible out and she overheated when I parked it.
I bought it with a recently replaced water pump with a clutch fan that is about 2" from the radiator. All the stock fans are within 1/2 to 1". I was given a stamped steel blade and aluminum spacer from a '65 coupe to move the fan closer but it would not fit. The bolt holes are 1 1/2" center to center on the steel blade and spacer, but are only 1 1/4" center to center on the water pump flange on my car.
Could this be a late model pump with a small flange for a 302 or 5.0 car? If it is a late model that used a serpentine belt would it cause the pump to spin in reverse on an earlier model like my '67? I thought I had read that somewhere but cannot find it.
I want to get this thing corrected. I think it is either the fan is too far from the radiator, or the water pump is wrong. It was suggested to use a fan shroud, but the fan doesn't extend far enough for one.
Please enlighten me. I need to solve this riddle and get this car to run as dependable as Ford intended. Thanks in advance for any and all help. Charlie

Charlie,
If your existing water pump was a reverse rotation, the lower water outlet would be on the drivers side. The standard flange for a small block pump 65-65 has the holes 1 1/4 apart or on a 1" radius. The fan and spacer must be from some other application. I checked Bob Mannels book for an application like you describe with the fan with no luck.You can always get a flexfan and universal spacer at a parts house. 17" flexfan move alot of air. Mike

Mike's right. Also, the reverse rotation pumps have a bigger fan bolt pattern than the regular rotation versions, so the pulleys don't interchange (although some aftermarket pulleys are slotted; which really confuses things). If the fan is that far away and you have no shroud, I'd say that is definitely your problem. ------------------

Mike & Charlie
Thanks for clearing things up. Confirming that the 1 1/4" bolt pattern is correct for the early models removes a couple of the variables from the problem. Now I am confused as to where my buddy got the fan and spacer he gave me if it is the wrong bolt pattern. He is a Ford man and a former Mustang owner. I know he was cleaning out his garage, but I didn't think he would give me something from perhaps a big block. I'll have to give him a call later today and give him the third degree.
