Water pump OEM FORD or GMB

I've been running the aluminum GMB pump (1301280AL on Rockauto) on the 455 in my '72 Bonneville for about 5 years now with no problems.

I have 20-25k miles on a GMB pump now and it hasn't leaked a drop. We'll see how long it goes, but so far I'm happy with it.

Me and various others I know have used GMB water pumps before with no issues.

I been running a Gmb pump for couple thousand miles now. Super cheap on rock auto, they also sell a high performance one. I bought both

In the 11000 or so km i have driven the vehicle i have already had 1) Water pump replacement, 2) Front engine cover slow leak ( awaiting parts on backorder) & 2 inspections covered under warranty.

I checked the old water pump and took it out by removing the front plate of the engine... The old water pump moves fine but it does make a squeaking noise and is quite old however it does move.

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

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.

The water pump was defective as well upon diagnostic. Leak in coolant as well. 2022 with 20k miles.
