Well, it's 60* outside but lucky me the car is overheating, I have 56k miles on the car and after a lot of researching online and such it sounds to be the water pump as many people have had the EXACT same issues as I am..

So the question is, where is the best place to buy a water pump from that I am not going to be blowing my $ when it goes out in 3 months.. The nearest dealer is 2hrs away so I would rather just order it since I'll be putting it on.. :/ Thanks for any advice and TIPS!!!

 

I think that this is a dealer-only part.

Don't forget to buy coolant.

 

Dont forget

 

I would stay away from alternatives on this one. I've had to do mine twice in 6 months because the cheap aftermarket part failed shortly thereafter. When I compared the 2 parts side by side while DIY'ing it, I could see a big difference in quality of casting materials and bearing/impeller. After you get the belt loosened, spin the tensioner pulley to see if it rattles. It's a good time to swap it if it does and do the belt too while you are at it. Good luck!

You're looking for a replacement electric coolant pump, right? (p/n 11517586925). Some of the associated hardware is aluminum "use only once", so you may need a few new bolts.

Here's an example.

HTH, and good luck!

I also have an 07 530i with an eletric water pump and I just did nine 3 weeks ago.. I replaced the water pump, Thermostat with housing, Serpentine Belt and 2 Gals Coolant..
