The media could not be loaded. Product worked great for a 2004 BMW 545i. Longevity will be the real test.

Purs like a kitten now

Easy replacement.

Installed very easily. Took 15 minutes. Seems like OEM. 3 months later all is well.

Great replacement for my leaking factory tank easy to install

Very good part not cheap like I was thinking it would be just like it would be if I got it from bmw and made the engine like for low coolant go away as well

I was expecting flimsy plastic and slightly different dimensions than the original. I was surprised at how durable this was and how it looked just like the oem. The floating indicator is a different color and has lost a little bit of color but who cares? They even went as far as having the molded lettering in German so it looks just like the original. For the price, this was the best deal that I found for this part.

Easy to install just need to drain some coolant from reservoir tank before removing.. Put a pan on the ground in case some coolant leaks. Would be good to put towel underneath to absorb some coolant as well. Don’t break off caps on old reservoir tank, you might need to use on new one. Twist and pull out sensor underneath tank before removing. Good luck 10-15 minute DIY
