Hi, hoping you can help here. I own a '66 Mustang. I pulled the original 289 out of it and iinstalled a 1993 347 Stroker, you know...more power!. I was a Chevy Dodge man until my wife bought this while I was forward deployed. I love my Mustang but I've definetly been schooled! She keeps overheating at lower speeds and we've tried just about everything we could think of. A friend that builds race cars said what we needed was a water pump with an impeller that turns counter clockwise. Does this sound right to you? I trust this guy, so I went looking for one. I can find them, but none of them match up with my block right. Any suggestions?Please help!
pumps up to around 1984 or 85 turned in a normal direction.. as they were driven by the inside face or V of the belt.. when ford went to a serpentine belt.. the water pump pulley became SMOOTH.. and the belt drove the pump from the BACK face of the belt... in a counter clockwise rotation.. which set of parts did you use when you installed the engine.. the 66 timing cover , water pump and pulleys??got pictures.. upload them to photobucket or one of the photo posting sites.. paste the links here so we can see what you have issues with..as for reverse and normal rotation impellers.. there are actually 3.. there are normal direction impellers that have a backwards slope that not only sling the water outwards but the taper on the impeller blades PUSHES it outward from the center.. there are reverse rotation impellers with the blade and the actual pump shape is reversed... these have the impeller blades facing the other direction.. so again it pushes water out from the center.. there are a few manufacturers who have come up with a universal impeller.. it has straight out from the center blades.. these will work in either direction but not as well as a proper directional impeller...you can see the lower right timing cover but thats the only counter rotation cover
