  • Vehicles that came through with a serpentine belt have a reverse flow water pump, this will work with your setup.

    Works like a charn

    I got this severe duty water pump to replace old, original one. Since then my 88 Mustang GT has been running a lot cooler and doesn't shut off from overheating. I personally recommend this product over the original.

    Love my new waterpump

    Just got my new severe duty police package water pump, and it looks great on my car, as well as keeping my stang running cool! (And we all know how important that is on a high performance motor). After easy mounting, with two very nice gaskets that came with water pump. I drove it today, car ran 20 degrees cooler, no matter how hard I pushed her! My 1989 mustang gt never ran better or cooler than today, love AM parts and easy order with fast delivery. Will order more parts tonight (E303 cam) also have told all my mustang friends, and they are ordering water pump and under drive pulleys to try and stay up with bad 89 stang, thanks American Muscle really enjoy putting your parts on my ride.

    Size, fit, and performance are what I got from this purchase...gave it 3 stars because the inner gasket was incorrect @ assembly and not catching it until the entire job was complete...started to fill when I noticed the leak....came with 2 outer gaskets....double check when buying which means taking the rear plate off to verify correct gasket....

    Great Price for a new Water Pump

    I haven't installed in my car yet, but the quality and the weight of it seems like this a great bang for your buck.
