Water pump GMB or OEM Volkswagen

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

I usually use rock auto and get the gmb outlander pump.

21 atlas with 120k here. No major issues. Just regular maintenance stuff. Replaced a leaky water pump with is a normal thing.

Changed it at 9 years / 93k. Belt was still fine but the water pump started to leak so did the timing belt job at the same time. Also upgraded the water pump with one with a metal impeller

I could smell coolant when my car was 6 months old. I was losing about 8 ounces a year. VW agreed to fix the water pump under warranty but I decided to wait. Five years later it hasn't gotten any worse.

2019 atlas (built 11/18) it had the water pump dine around 60k, nothing else engine wise, just rolled 95k.

My mk7 water pump went out at 76k and will probably need to be done soon I’m at 135k now. I live in the heat of arizona too. It really gets tested here.

The water pumps are plastic. Heat and plastic don’t go well together. My MK6 has had at least 3 water pumps and sitting at 120k.

My 2012 GTI has 175,000 Kms and is on Water pump #4.

Water pump has been replaced 5 times. Twice under warranty. Had I been smart I would’ve gone with an aftermarket metal pump.
