People like the Stewart water pump, but since that's harder to get in Europe, I went with an skf pump and it's been fine so far.
Pros: fine so far

That\u2019s what I have in mine and I\u2019ve had zero issue with the water pump.
Pros: zero issue
Went with a kit from SKF this time, seems a bit beefier, still plastic...
Pros: a bit beefier
Cons: still plastic
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.
Cons: smell of coolant
It turns out the pump (shown mounted) is the wrong size for the factory pulley ! The pulley cannot attach -- too much play and holes don't line up. Compare with old pump (shown on the ground) where the bearing is wider and fits snuggly to the pulley.
Cons: wrong size for pulley

I got all aluminum Pierburg water pump to replace (working) VDO water pump. After putting everything back together, bleeding the system, I turned on the car, drove 40 miles with a couple on and off cycles and then shut it off for a couple of hours. I came back, started the car, I got the low coolant level warning, understandable, air escaped the system (I guess I didn't bleed it enough lol). Topped it off, drove 20 miles back home and then heating suddenly stopped working and coolant temp started rising. Went from 95 C to 100, then 105 and that's when I shut the car off, didn't want it to overheat. Ever since then, my pump works intermittently. I had a laptop set up next to me with INPA on today and drove close to the house to have the car ready for emissions (thank God!). After bleeding the system two more times yesterday it seemed like it was fine but while driving today, after maybe 20 minutes of driving, the pump stopped working and would not come back on again. It was like trying, the percentage rose to 30-35% and then back to zero immediately. Temperature went from 90 C to around 110 C rather quick obviously. Then out of nowhere, it started working again for a bit. Got close to the store I was going to, and it stopped working again. I was able to pull into the parking lot as it got to 120 C and got a yellow overheating warning. On my way back home from the store, the pump only started working again maybe 3 minutes from home, had to stop once and then turn off the car and keep rolling most of the way to not let it overheat. Also, there's no heating from the vents until I set it to 28 C but at the same time there's no movement from the pump in INPA.
Pros: aluminum pump, peace of mind
Cons: pump works intermittently, overheating
