Water pump Gates or OEM BMW

My experience with the N52 was great honestly. I owned a 2007 328i from 2007-2019 and put over 120,000 miles on it. The only engine issues it had were the water pump failing at 90,000, and the oil filter housing gasket leaking.

I have a Gates part with a plastic impeller in my car now and it's been attached to that motor since late 2015 with no issues when it was in my e34 and isn't showing any issues now in my E30.

Gates all the way. I have just a basic timing kit and water pump and i auto-x mine in the summer. Haven't had a single little problem so far.

Once I removed the thermostat, I felt in the port and although the impeller felt ok, it spun freely; not smooth like a bearing but rough like it was dragging. Since I was able to freely turn the impeller through the thermostat hole, I have to assume my water pump is failed.

I had a gates kit on my Subaru and the water pump failed and leaked after less than 1000 miles.

The water pumps i’ve seen leak a few times on the v6 hondas.

Gates is crap. Bought their water pump and it failed less than a year and leaked the whole time.

Mine broke in less than 500 miles and their replacement broke too (which I paid for till I returned them the faulty one back) in less than 500 miles on an Audi A1. Now they have my money for 2 water pumps and I paid for labour costs of replacing twice, and waiting for a refund decision for more than a month. AVOID!!!

Don’t use a Gates kit or if you do purchase the Gates kit without the water pump and get a different brand water pump. Gates water pumps have an enormously high failure rate in the last several years and it sucks to have to do the job twice.

Water pump failed on the gates timing belt kit and engine shredded only 16000 miles on it
