JSD AUTO PARTS Replacement for 17137552546 Coolant Expansion Overflow Tank Reservoir fit 2007-2013 BMW E70 X5 X6

Physically it does fit exactly and looks exactly like the OEM for a BMW E70. UNFORTUNATELY float or something else was broken internally. Rattles when empty and doesn't read coolant level properly when filled. Cap doesn't fit snuggly like it does on OEM or other 3rd party reservoirs, not sure it will vent properly. Waste of $50 for me, hopefully you have better luck.

My overflow tank cracked and I bought this one. It has been on my x6 for about 4 months now and it still working fine. If you are going to install it yourself be advised that it is kind of tricky. As of today I have no complaints. Great aftermarket tank.

this was a perfect fit for my 2011 bmw x5. it also came with the replacement coolant sensor. was skeptical about part might leak or made of some cheap material but definitely not cheap material and no leaks. excellent replacement coolant expansion tank for 2011 bmw x5. i highly recommend this part to anyone looking to replace their old or damaged part.

Worked as well as the factory expansion tank. No issues with coolant sensor as reported by other aftermarket tanks. We installed it on a 2015 X5 35idrive.

This one actually works - appears identical quality to OEM. I purchased an eb&y reservoir that didn't resolve the low coolant level warning. This one does.

Works great perfect fit.

Excellent replacement, equal or better than the oem tank. Took minutes to install. Comes with temp sensor.

Product arrived as described. Fit was exact. Sensor was damaged (possibly during shipping).
