Expansion Tank Reviews - 2006 BMW X3

Behr | W0133-1797677

I bought this expansion tank to replace one I bought at a Autozone. This was less expensive by half and much better quality

The reservoir seems to be of high quality and I received it within 2 days of placing the order! I will certainly order from theee guys again.

I had ordered 3 BMW OEM parts on this order. The parts came in a timely manner and were exactly what I had ordered. I have ordered from PartsGeek probably six or seven times without any issues. Once I ordered the wrong part and followed the return policy with no problems. So far a happy customer...
