WATER PUMP ROTATION

1995 Ford Mustang

Engine Cooling problem

OK, I'm baffled. The fins in my water pump are curved, creating a "scoop", but they turn the opposite direction (back of fins moving forward). Is this correct? I have a 95 mustang 5.0 V8. The water pump runs counter clockwise due to the serpentine system (engine runs clockwise). I have checked every auto part store and the replacement pumps are all the same as mine.

NAPA says their's is a "clockwise" rotation, but one I found on AmericanMuscle.com that is listed as "Reverse-rotation: Counterclockwise"...but they are the SAME water pump!

I find it hard to believe that EVERY part store has the wrong water pump. Are the fins supposed to run with the back of the fin pushing against the water?

You need the reverse rotation - opposite of crankshaft type water pump. The pic I attached is correct as well as your pics. I believe NAPA simply has an error in their system, their picture is correct but it should say "counter clockwise" . I have checked several part stores online and all have the same style of water pump, counter clockwise, for the 5.0L . the 3.8L engine, however, does use a clockwise style water pump, but it looks like the second pic I posted below..

Counter Clockwise for 5.0L
