2007 N52 Electric Water Pump Failed

So, yesterday my wife calls me saying the car is overheating, the heat doesn't work and that the car has no power. So---she gets the car off into a parking lot and after work I go to the car, do a visual---no leaks, coolant level good. Has to be a pump and/or T-stat. I have the car towed to my local independent BMW shop.

Today I get the call confirming the water pump is shot. So, for $945 out the door, I got a new BMW water pump, a Wahler thermostat, a full coolant flush. Not terribly bad for the level of work to do this job--but, very disappointing that at only 78,000 miles, the pump is bad. My indy shop actually stocks these pumps due to the failure rates.

Man, that sucks but you could save yourself some skrilla by changing it yourself. Bavauto just posted a vid on changing one of these on a E9x series. I'll tell you though, I'm worried about these damn pumps!

I'll be replacing mine soon as preventative maintenance.

According to the service records, the first one went at 60k. I am approaching 120k, so I might as well do it before the snow flies.


$945 is pretty good. I'll be doing mine myself.

+1

Ours is at 119,000 miles and so far so good but we're spending the week of Christmas in the mountains and I don't want to risk it failing on the trip. Haven't done it yet because I'm willing to chance it as long as we're within an affordable tow back home.

Already have the pump, thermostat, gallon of coolant and distilled water.

Essentially, I paid the shop $276 in labor. Pump was $527, T-stat was $96, coolant $24. So whatever. I watched the DIY that bavauto put up; i'd rather pay the three hours of labor to the shop and let the pros handle this one.

I can't fault you there one bit.

The really fortunate thing was that it happened on Monday--we were 200 Miles away from home over the weekend!

yeah I just read that thread. The car has always had BMW coolant--and the new coolant was BMW coolant, so the pump should never fail!

Impossible. If you used the right coolant that cannot happen. The words escape me. Wait, here they are:

"In writing, bonded? You have proof? Or is this just your opinion?

I say this because you are telling people it's OK to go against the manufacturer. And a failed electric water pump is damn expensive to buy and replace."

See? If you had used the correct coolant, this could have never happened.

Must be an epidemic My wife called me today with the exact same symptoms for her '07 X3. I have a replacement pump and thermostat on order to replace on Wednesday evening. Can't wait...

My wife's car is a 2007 with the N52 engine and I replaced the water pump and t-stat preventatively last winter at about 85k miles. She drives 450 miles to see her parents all the time and I couldn't afford a breakdown while she was on the road. I have done a lot of BMW water pump replacements but this job is a major PITA. I did my daughter's 325i with N52 engine in about 1.5 hrs and it was pretty easy to get at everything. The AWD nature of the X3 is a different story. I had to go out and buy special tools to help reach some of the bolts and screws. Total time was about 6 hours and I needed several beers afterwards before things got back to normal. The good news is that everything went well and the car has had no problems. $945 out the door is a decent price from a dealer.

If anyone is interested my car is a 6-speed manual and is for sale in the classified and on autotrader.com.

The job for me was pretty straightforward. I recruited another set of hands, he and I have torn down and reassembled many things on many different cars, so this was relatively simple. Took us 4 hours from arriving in the garage to setting the car to do the self-bleed procedure. We found no way to avoid getting coolant all over everything, but other than that the job wasn't tough. We pulled the cooling fan out and it gave plenty of room to work from both the top and bottom simultaneously. I could see this being a serious pain in the hind-end for one man to tackle without having done it before. Having a full complement of u-joints and extensions was key to the ease of removal and installation. Having now done it, if it ever goes bad again, I could knock it out solo in about the same amount of time or less.
