I got lucky I was going thru my paperwork and I did purchase extended warranty with Protective Select and they are going to cover the water pump. But they are only going to pay $900. BMW is charging them $990. So I got to pay a $100 deductible and $90 to BMW. The guy at BMW told me that it would of cost me $1,200 if I did not have warranty. 190 is better than 1,200.

My Protective Select Warranty Expires at 112,500 miles.

Thanks Dimevivo... Having made the mistake of replacing my thermostat and NOT the water pump on my my e60 (N52), i could seriously kick myself since the water pump is about to go.

I will say, the t-stat job simply sucked. It took me hours to figure out the best angles to reach the hose clamps. Once i sorted that out, it was easy.... but i needed tiny munchkin hands to get into the small spaces.

So, soon I will be replacing the water pump. There are a few great OEM discounters from which I will buy the part. I like these guys:

Perhaps I will do a DIY for this one since I didnt last time. And NOT do it in the dead of winter on a cold garage floor.

I replace the water pump, thermostat and several coolant hoses last week and this job is a serious PITA, and not something I’d recommend for a noob. However, like the poster before me, having small hands would make this task easier.

With that said, there is a great video DIY on YouTube that was posted by BavAuto. The only problem with the video is that I see makes it seem deceptively easy to do. Also, if you’re doing it on jack stands, laying on your back, a faceshield would be helpful. But do wear safety glasses at the very least. I drained everyth8ng thoroughly, but still...

Good luck to all of those who take on this job. It’s very rewarding once finished.
