BMW EMP Stewart High Flow Water Pump

Normally I'm cautious around non-OEM parts like this. I had this put in my Z3 back in January and it has worked flawlessly so far. It required no modification and fit in perfectly as it was. Definitely worth the piece of mind that it provides over the OEM plastic one.

Does exactly what it says on the tin, peace of mind investment.All despite USPS best attempt to frustrate the transaction by damaging the first consignment Ed at Bimmerbum organised a replacement dispatch we got there in the end. Recommended. Charles Johnston

feels very high tech, like it came from the USS enterprise. Also it keeps my car cool, so that's a plus.

Works great installed a year ago with no leaks or failure and engine temps are reduced under acceleration

Great price...fast shipping

ok

I bought the EMP Stewart 4 years ago as preventive maintenance to my 2003 BMW Z4: it has the apparent reputation of being the bee's knees, the ant's pants, and the cat's pajamas of water pumps. I paid full access price for the rodeo...It replaced a perfectly working 80K miles and 8 year old original BMW water pump which was supposed to be a ticking time bomb...Well... After 4 years and 60K miles it is leaking.I've decided to replace it with this one  FMI 20669 Premium Performance New Water Pump  and will send it back to the manufacturer to get a replacement (since they won't issue refunds) and probably resell it.I'll update this review to let you know if the warranty is at least any good.

The media could not be loaded.  Failed after 33,000 miles and three years of freeway driving. The design looks good. The castings seem solid. The main bearing did not last long at all. Seal failure was total.This seems to be a general problem with these pumps. Plainly the bearing in these pumps is not up to the job.
