Owner reviews for water pump

Just had my water pump replaced about a month ago to resolve the issue during my 40k service — hoping it holds. Techs at local VW dealership took about two days to locate the issue and make sure it could hold pressure. I was covered under power train warranty

Well I test drove the car and put about 70 miles on it, everything is in good working order no leaks no issues runs like new

I have been running the Graf AL pump for about 10k so not long enough to give a full assessment, but the quality was awesome and very pleased with it.

In the end I just went with the genuine vw part from FCP. The original lasted 149k miles and I have never heard of an OEM pump leaking, just the earlier design impeller breaking apart. And I know that problem has been rectified through Vw. So as long as it holds together for at least 100k miles, I now have a lifetime warranty through FCP.

I have their water pump on my Rx7, it's been A-Okay for over 3 years.

Graf does make an AL housing pump which I used this last time. Time will tell if it holds up better the the Rein plastic AM one installed in the CC.

The water pump broke (fortunately stuck open so no major damage). The part is RIDICULOUSLY expensive (it looks like an artificial heart) and was on a month-long backorder but everything went smoothly.

metal impellers definetely can eff up your setup. I had one on my 2.0 jetta. and it completely froze, and caused me to overheat, which killed my headgasket. The engine never fully recovered from that.

Just had my second Continental pump crack withon 20k

My '89 325iX doesn't put out much heat at idle, but as soon as I rev it to 2000 rpm, the heat starts coming out of the vents. At idle it is around 65°F air and at 2000 rpm it goes up to around 95°F (it is ~35°F outside today). I noticed a whistling noise that seems to come from the water pump at idle. Once the car got to normal operating temperature, I noticed that at idle coolant stopped coming out of the bleed hole. If I revved the engine a bit, coolant would flow. I replaced the water pump (Graf) 2900 miles and 3.5 months ago. My intuition is that the water pump isn't generating sufficient pressure at idle to move the coolant through the heater core.
