        5 Top Rated Questions

        What is the difference between the Severe Duty Police pumps and the SR high performance pumps?

        • The severe duty police pump is a heavier duty version of the factory style water pump that originally came on that car, whereas, the SR performance water pump is a high performance pump that has a reversed rotation that can output a higher amount of coolant per minute and to minimize any hot spots in the engine.

        My '92 5.0 temp loves to creep up and drop over and over both while driving and idling. I've flushed my system thoroughly and replaced hoses, had the radiator, water pump, fan clutch and thermostat replaced over the past 3 years. I have a good handful of bolt-on mods. I wonder if the stock water pump (from autozone) isn't cutting it. Should I go for this one or do I need a high flow performance water pump?

        • This Severe Duty Police Package Water Pump by OPR will help bring down coolant temps, however, if your vehicle is over heating quite a bit, we would highly recommend a high flow pump. If the temperature only creeps up occasionally, I would recommend looking into the addition of a new fan on the front side of the radiator and reversing its polarity. It could be wired in via an on/off switch, or even a thermostatic controller to automatically turn on when the coolant temperature starts to creep up.

        What exactly are the differences between the OPR Water Pump - Severe Duty Police Package and the OPR Replacement water pump (Item 525130)?

        • The OPR Replacement Water Pump is a reproduction of the OEM 5.0L water pump found on the H.O. 5.0L Foxbody Mustangs. The OPR Water Pump - Severe Duty Police Package is a reproduction of the water pumps supplied on SSP Mustangs. The SSP (Severe Service Package) Mustangs featured increased cooling ability, thanks to a more efficient water pump design, silicone hoses, and an engine oil cooler to handle the long idle times expected for Police Mustangs.

        Can anyone tell me the difference between the Severe Duty Police Package and the Ford Racing water pumps? My supercharged 1987 Saleen doesn't overheat but it does run hotter than I would like especially on hot summer days in stop and go traffic. Going to replace radiator with a Mishimoto and will change water pump while it is apart.

        • The OPR Water Pump - Severe Duty Police Package is made to the same specs as the OEM police package waterpumps. The Ford Performance water pump will be a standard design, and will not increase flow over OEM.

            I like it

            Easy to install. Haven't ran it yet but if it works as good as it looks it will work good. The car is being rebuilt, so as soon as the rest of the car is back together we will test it out.

            Police package water pump

            So far so still isn’t on the road but have had it leaks and seems to be working good! Shipping was fast and pump was as described! Came with gaskets but All i did was change to felpro gaskets.

            Good pump, wrong gasket

            Received the pump with two of the same gaskets instead of the two different ones I needed. Bought a Felpro kit and got it installed. Worked great right up until the heater core broke

            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....
