Improved waterpumps?
Hey everyone,
My E92's waterpump is starting to fail again-mechanic said he's starting to see some very slight leaks with it. It was replaced back in 2012 and probably has 20K miles on it. Did some searching but couldn't find anything but are there improved waterpumps out there in the aftermarket (I saw that ECS has a Vemo Q+) or has BMW issued newer improved ones that don't suck? I remember back in the day, BMW redesigned the E36 waterpumps (mine failed) for the M50/52 and S50/52 because of the terrible design using plastic impeller blades-they upgraded them to metal. Ugh Thanks!

I went with the OEM non BMW labeled pump. The plastic housing cracked in 4 months and started leaking everywhere....that isnt a common issue and it was replaced under warranty. But as far as i know there isnt any upgraded pump.
Only other thing I can note is that the 1st pump was man'd in early 2014 and this one was Q2 2015. I compared the digits that were stamped on each one and plenty of them did not match up...not sure what that means but the OEM may have a new revision? |

Dude I was just going to create a post. I had my water pump replaced last year 7/1/14 and it failed again this month! 2 months outside the warranty I am fucking livid and absolutely done with this POS car.
Where is the most cost effective place to get a water pump ? thermostat combo? |

The newer water pumps BMW has are improved from what I hear. However it's still electric so there is always going to be risk of them failing again.
If you can't afford the upkeep of a BMW, Hyundai accents are going for 13k brand new

when i replaced my water pump last year on my 2008, the old pump was seimens VDO and the new one (BMW brand) was marked as Continental, so they did change. I've only had it in for 10k miles, but no issues (the fan seems to come on more than it used to, but not full blast like a failing waterpump)

Its funny how you guys always use this as an excuse for unreliability. Water pump is not an "upkeep" or maintenance item. Do you see a recommended change interval that you didn't make up yourself? Is there any predictability of when its going to fail (mine lasted 120k miles. would have been a waste of money to have replaced it at the various mileage people claim it COULD fail). Do you know of any upkeep items that are working like new, the dealer doesn't recommend you changing and the next day has you calling a tow truck? Upkeep cost is not the problem. Unreliable is the problem. Are injectors, fuel pumps, SOS call malfunctions, wastegate rattle also upkeep items? Do you know other cars where these routinely break? You can get away with shitty gaskets that fail prematurely and chalk it up as "upkeep" but everything mentioned above is just plain ole unreliability.

Hell, I'd pay $2K for pump that won't fail like it does on these cars.

My stock VDO pump lasted to about 80K. The replacement was Continental. Can't comment on its quality just yet, only have about 9k miles on it.
I don't think there is an aftermarket/improved pump that I know of.

Maintaining means fixing the parts that break like a WP for example. Some people aren't ready for that and believe that a BMW should be as reliable as any other car because they paid so much for their used 335i lol

I changed mine at 45k cuz it had a leak. I'm ready to change it again if it breaks and for sure it will. BMWs ain't cheap I feel you on the thought of being stranded. Sucks huh. I think about that every time I take a long trip with my wife and kid. Lol

Well the 2011 IS-F is a great car, just think of it as a more luxurious M3 that doesn't break.
I really wish someone would make a mechanical water pump for the N54 that wouldn't break. Heck if someone fixed the IMS issue in the 996, that should be possible |

Thermostat 1 gallon of BMW coolant German-made Vemo Q+ water pump with mounting hardware Coolant inlet and outlet hose, as well as the water pump hose Expansion tank with cap Cost $620 Considering i plan on building and keeping this car and it already has a jb4, dp, brake upgrade, 100,000 mile service i figured it made sence to order these hoses while im there. It sucks coming from an e36 where i could buy an upgraded stewart water pump and not having that option in this chassis. Someone really needs to make one simular, that being said im not opposed to an electric water pump, less strain on the engine = more power |

Not sure which ecs kit it is, but make sure in includes a new thermostat. You don't want to do this job twice. Also, you should replace the thin coolant line that goes across the front of the car above the fan as it is prone to breaking.

My original pump lasted 199k. I'm 38k into the second one. Someone should design an aftermarket one that either lasts longer or runs some lines to a pump in a location thats easy to change. Cheaper, sturdier, etc. Something.
