For years Vanagon coolant expansion tanks have been the source of great disappointment. This is not because the original design was flawed. In fact, the original tanks were known to last well over 20 years. The disappointment began when the original VW-made tanks became obsolete, and many different manufacturers started producing an aftermarket tank—most of which are... well, junk. Some tanks would literally melt the first time the engine got a little too hot. We have experimented with all of the plastic iterations that have appeared over the years. Truth be told, most any tank currently available will last a few years. If you are willing to keep an eye on your OEM-style plastic tank, they are available on our website here.

If you want to install your tank and FORGET ABOUT IT, this is the tank for you. Every tank is hand-assembled and welded just down the road from our shop. This hand made all-aluminum coolant expansion tank features a sight glass that is visible from behind the license plate, accepts your original sensor and installs right into your original bracket. The installation couldn't be easier! 

Important Product Note: This tank no longer includes a new coolant level sensor as of January 15, 2021. We recommend you install the original OE sensor right into this tank. We also have aftermarket sensors and connector housings available on our website, sold separately.
