Water pump OEM FORD or GRAF

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.

If it *is* leaking you might want to consider replacing it with a Graf alloy-bodied pump which won’t be affected by heat and exposure to oil, the usual causes of eventual failure of the plastic pumps.

Graf has been pretty good to me.

I have the Graf brand on mine, replaced mine at around 120k miles. It’s aluminum and has aluminum impeller also.

I installed one on me 325i 12k miles ago, no issues so far, it was part of the FCP euro water pump kits

I had a 2017 GT… here are common issues that I also ended up having:

Water pump went out at 60k

AC started to struggle, especially on hot days, around 70k miles

they slapped the fucking water pump behind the timing cover ?? Just go German engineering and make an electric water pump so you aren’t doing a chain service to do a water pump.

the only thing that’s had any problems is a water pump

the metal fins are spot welded like shit on these cheap metal waterpumps. my graf pump also started to leak from the weep hole after a year too

Here’s my experience with the 2019 for what it’s worth:

Bought a 2019 with 5.0, xlt with 20k miles for $41k in Aug 2022.

-Water pump and vct’s replaced at 50k miles.

-New engine at 98k miles due to oil consumption (2 dealerships and 4 months later). Replaced in Aug of 2024

-102k miles the trans started acting funny, fully grenading at 112k miles. Replaced Feb of 2025

-126k miles and the transmission cooler fails midway through a 3hour trip with the pop up camper and family in tow.
