Water pump AISIN or OEM BMW

I have only got my AISIN water pumps when ordering timbing belt replacement kits which include a new water pump, but they always came with a quality seal for the pump.

A Bosch o2 sensor is going to work just like oem, an aisin water pump is going to last as long as oem. But moog balljoints don\u2019t.

The AISIN kit is the same water pump and tensioner as the OEM equivalent with out the Honda stamped on it. I personally would still get the OEM timing and Drive belt though.

I paid similar for a BMW TBF, however, another garage told me that the garage I went to was known for charging high prices. I always shop around when the price is in the hundreds so I'm confident I wasn't ripped off.

I’ve changed two water pumps with Aisin brand WP’s from EBay … about 120$ each … and I’ve done fine so far, logged over 100K on them first and then so,d the car. it’s still going strong. the second is going strong in my current car.

I had my 2008 BMW 135i E88 for going on 14 years, it's about to hit 70k miles and looks like new. I've done a couple bolt-ones (IC, charge pipe, Cobb tune). It's been a great car and a blast to drive. I did replace the water pump this past summer otherwise normal maintenance.

I’m on year 3 of a 2020 M240ix and it has cost me nothing besides regular maintenance and premium fuel. Now I expect that to change soonish, as at my last oil change I was told my water pump has a very slow leak and, at some point, will need to be replaced to the tune of $2k.

I've owned my 2013 535i M Sport since 2018 with 44k miles. Other than the regular maintenance items... 2021- oil filter canister gasket replacement -$ 800 ( I think. I can't find the receipt) 2024- passenger valve cover gasket- $660 Driver's door handle replacement -$250 2025- water pump and thermostat- $1750

I had an 2001 740iL that I traded an old truck for. The electronics are kind of a nightmare, the water pump has a plastic impeller that likes to randomly explode and shoot plastic all through the cooling system. You can buy one with a metal impeller that solves this.

The Aisin kits are fine. I would not use a gates kit; the water pumps are junk and so are the tensioners
