Rein CPE0030P Expansion Tank Cap

Great replacement that worked as advertised. I have no complaints

This is working great on my 2004 Z4.

Everything was ok.

I noticed some leaking coolant from somewhere. Thought I had a faulty/cracked expansion tank. I wrapped a small piece of cloth around the cap threads. Realized the leak was coming from the cap. Replaced with this.. problem solved.

Works like the original. I purchased a cheaper one (from another seller) and it did not hold pressure to the correct bars.

Excellent replacement for ‘07 BMW X3. No leaks and it seems better quality than genuine brand.

Good price but it's not right cap radiator for my bmw 325i 1992 e36 and it's not same of the picture product what show there. I think that this is a fuel gas cap for BMW E46

The product fit perfectly in my car.
