AISIN AFTERMARKET WPF-002 New Engine Water Pump with Gaskets - Compatible with Select Subaru Baja, Forester, Impreza, Legacy, Outback

Bought this for our 2001 Outback with the 2.5. The previous owner had paid a shoddy mechanic to change the timing belt and water pump and he used one of those cheap online off brand kits. It started leaking within about 5k miles as evidences by dried coolant on the oil filter. I ordered this and expect it to last much longer.

During a timing belt change I decided to swap the water pump as most people do to avoid having to do it all over again down the road. I purchased this pump as it came recommended from a friend and also comes with a gasket which the Gates pump did not. This pump has a slightly different impeller design than the OEM model but appears to work just as well. The gasket is a real gem in this kit as it is quite beefy and I did not worry about it leaking one bit after the install. Do yourself a favor and put some RTV on the gasket to hold it to the pump during install. This makes it way easier to get set correctly. The pump also comes with the corner vibration rubber piece AND a thermostat seal. I purchased a new thermostat that came with one so I did not need it but I found this to be a very nice addition and applaud Aisin for giving you everything you need to swap this pump. Overall I am very happy with this pump. I have been running it for about a week without signs of issue. This pump is competitively priced with the Gates pump and having purchased and installed both, I would recommend this one over the Gates as it comes with a proper gasket and feels like it won't let me down in 10k miles.

Casting of the pump was a direct fit, gasket for the thermostat was good quality, metal gasket for the actual pump was quality. Only thing I did not like was the impeller was different from OEM. It was the open type found on a gates type. It is a Japanese OEM supplier, so I trust it is OEM quality. Otherwise it is great quality for a great price! Beats forking over $150 to Subaru, everything else was 100% OEM exact. When removing, double check all screws are out, there is a hidden one under the roller that makes it seem stuck on the block, it comes off real easy, just suctioned on a bit. Would buy again!

Was worried that for the price it might be be a knock-off. But it's the real deal. Installed effortlessly and works like oem.

It fit perfectly on my 97 Subaru Legacy GT with an EJ25D. It came with all three seals, and feels extremely well made. Definitely recommend versus some of the non-Japanese parts.

It works but it doesn’t have the same impeller as pictured.

There are several manufacturers out there and I went for the Aisin since they are a the largest Japanese water pump manufacturer and (I think) the OEM for my Subaru. The kit comes with a thermostat gasket (and I would recommend changing the thermostat when you change the water pump), a nice metal gasket for the water pump and a little segment of housing gasket. Mine fit very well and looks like the OEM part. I'd buy this kit again.

I bought a used Legacy that had a small coolant leak. Come to find out, the water pump gasket was the culprit. Which is why I just bought the water pump kit. The previous owner had done all the timing belt/head gasket work, but I didn't want to assume that the old parts were good, so I replaced the water pump as well as the gasket. This comes with a metal crush style gasket. I liked it more than the particle gasket that was on the pump that was in the car already. As the particle gasket was the leak. Everything fit like it should! Runs without leaks! Hopefully it will stay that way! Only had it on for a week, but no issues with coolant leaking.

High Quality - Excellent price

Genuine Japan aisin pump with thermostat gasket and little z gasket but was missing housing to block gasket. I had purchased an OEM metal gasket anyways but item depicts the mating surface gasket as part of the package
