Water pump Gates or GRAF

I put a gates on my 2005 in August. No issues so far.

Graf here. 15k miles/ 2 years, no problems.

I got a metal impeller gates and I’ve been beating on it for five years or more without any hiccups.

I use on my 12v and 24v VR6 engines, Eurowise aluminum thermostat housing and 42DD stainless steel crack pipe. Water pump I use GRAF or Hepu for its metal impeller.

I've also had a Graf I think it was, it did have a metal impeller, which started leaking after 7 yrs.

During COVID, that water pump was on backorder from Ford so I used one from Gates. I guess Gates had a bad batch and 2 of their's failed in the span of less than a year.

what I had problems with is with Graf water pump, that was included as part of FCP euro cooling system kit, water pump seal around the bearing started pouring coolant like a waterfall after only 11k miles, I replaced it with a Stewart pump

The only one to really avoid out of the 5 choices on Rockauto is the Gates, because of the cheap stamped impeller. Personally, I would not go with an aluminum pump body in this application, but that's just my opinion after working on vehicles for a living for 45+ years.

I used a Gates pump the first time and it leaked. I uninstalled it, cleaned everything up, regreased all the seals, and reinstalled it it... still leaked. Turns out the Gates water pumps for the ecodiesel are just garbage.

I have Gates start leaking within 10k of installation.
