I am usually a “motorcraft” kind of guy. But for this price I figured it’s worth a try.I almost ordered both pumps just to see where the double and triple price quality is. But I did not. So Gates will do for this round. I can not speak of the longevity of this product either. I wish those who have over 100k miles on a Gates would give updates on here. Instead of only the ones that failed complaining. I’m sure there are many more making it well over 100k than the ones who failed. Also Gates has videos and literature stating how not to use sealant on the gasket. How many that failed will admit they added sealant to the gasket? Upon inspection the pump seems to look fine to me. Mostly the bearing up front. Since it holds so much weight and tension from fan and pulley. Machining seems fine. Not sure which impeller metal is best. But galvanized should be fine. I tried to get photos of the bearing and internal side where shaft is. Also you can see from my photos that the gasket provided stays in place very well with out any holding it. Also you can see it came with the 90 elbow for earlier 7.3 engines. There’s a o ring for the lower connectors. Wether your is straight or curved. A thermostat gasket, all though my stat had the gasket attached. While I have it all off I ordered a billet thermostat housing. I bought a motorcraft stamped steel one two years ago when I did hoses, and it’s rusted already. The one I got is hiwow. I found it on amazon. I seems nice enough. Has 3 color options and much cheaper than others with names printed on them. I hope this review and pics are helpful to someone. I know I read and read forever trying to decide which pump. Even though I can afford a more expensive one I’m getting wiser or dumber as I age. I will update this if I ever have an issue. And my truck only gets 8-10k a year on it. So it’ll be a very long time before I can attest to its longevity. But I do like updating amazon reviews when I come across them here and there. We will see.... Update 5/11/20- still working fine. No issues. Prob less than 4K miles. No leaks. Truck stays cool. About to go through a summer here in the desert. If I remember I’ll do an update afterwards. 11/04/20- Almost been a year. No problems. Made it through summer fine. Thermostat never read hot at all. Prob only around 5-6k on it though. 7/1/21- still works great so far. 10/25/22- still working great. Made it through another Vegas summer. 01-2023 sold truck. Pump was fine still. Prob ending up putting 15k ish on it. ... show more

    • Great water pump
This water pump is just as good as Motocraft and a fraction of the cost. Gates is a very good and trusted name (usually made in the US or Canada) and this part was easily installed and has worked flawlessly. The hardest part of the water pump job was removing the fan, this part was a perfect fit and installed in under 10 min on my '99 7.3 Powerstroke. I installed mine about 2 months ago now and I have put about 2K miles on it. 500 miles of that was pulling a 19K lb horse trailer. The water pump has performed flawlessly and I have full faith in my truck again. ... show more

    • Solid Product
Had a leak in the Water Pump. Called Ford and they had them on national backorder. They were $399 too. I read the reviews for this and decided to purchase. Bolted right on with no issues. Very strong and made of quality. While I had everything apart, I went ahead and swapped the upper/lower hoses, fan clutch and fan. The ONLY thing that was tricky is the lower hose outlet is bigger than the original (longer). I had to trim the lower hose bc of the extension the WP has. The hose is also a bit smaller so I had to work the end in for a minute. For the money you really can't go wrong with this. Solved the leak issue and appears to be running smooth. Here is what I replaced.

    • Worked great on my early 1999 F-350 7.3L diesel
This Gates water pump easily fit my early 1999 Ford F-350 7.3L diesel truck, and works great. No leaks, and easy to install. I used some grease to hold the gasket into place during install for a proper fit, using a few of the longer bolts installed during placement as a guide. The seal provided is preformed, fits great, and does not require any sealant whatsoever, so refrain from apply any additional sealant as it is totally not necessary. All gaskets were included, even for the thermostat. I recommend getting the Ford OEM thermostat from Amazon as well during the replacement of the water pump. I also Installed the (HHY?) billet aluminum thermostat housing as well with this pump as my old OEM tin preformed one was heavily corroded and leaking. I am very happy with the outcome, and hope this new pump lasts! Time will tell. ... show more

    • 7.3 Water pump
Pump seems to be of good quality, easy install for the driveway mechanic. Included water distribution fitting is too large for existing hoses, 1-7/8" instead of 1-5/8" like original fitting.

    • Great water pump and my opinion!
First off I am not saying anything bad about this water pump or seller great people to do business with. It's my 3rd water pump for different cars will not buy anything else.Very nice water pump! I put it on my truck 4 times to make sure it wasn't something I was doing! Last time I took it to a shop and they told me it wasn't laying flat ! I asked him if it could be my motor and he told me that he checked it and it wasn't the problem! I will not give this water pump a bad review because it is a great pump and a lot of different things could make this happen! I wrote this just because if someone else is having problems sealing check water pump make sure it's level! To bad it took me passed me return date but with cancer and putting it on so many times it took a little more times! Lol but I get the money I will order another from this company! Thank you all and good luck!! ... show more
