You can replace your coolant resevoir
The coolant reservoir was delivered quickly and the quality is good. Also, it was a perfect fit for my VW Passat. After viewing a You Tube video, I was able to change out this part in less than an hour and I am not a mechanic. One suggestion I have is to get new clamps that you can tighten with a screw driver instead of trying to reuse the factory clamps which are nearly impossible to reinstall.
