Water pump Hepu or OEM Volkswagen

Ive reinstalled another new HEPU(made in germany) pump due to mileage. I don't think anything is wrong with the old one. When I cleaned the o-ring seal contact area on the block it was corroded right where it left an imprint.

If you're worried, replace both the water pump and thermostat. I would use a Mahle, Facet, or Wahler thermostat, and either a Hepu or Graf water 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.

Update. The replacement HEPU water pump is now leaking.. from the freeze plug…

Replacement HEPU water pump is now leaking… from the freeze plug.. gonna let it ride and try a different brand when I change the belt in 50K miles

I’ve now popped two water pumps. Each of them have sprung a leak from the freeze plug. I seat the pump and o-ring by hand then torque bolts to spec.. each time they’ve been good for about a month or so, then start leaking from the freeze plug.. both pumps have been made by HEPU.

I had a defective hepu pump that leaked also. Only had about 20k miles on it
