JJ,
The expansion is an important part of the WBX coolant system. In conjunction
with the pressure cap it automatically bleeds the system of air. When hot
coolants and air needs to flow into the overflow. When cooling down coolant
only is drawn back into the system.

Subject: [VANAGON] Expansion tank not connected

Howdy

On my WBX, the expansion tank is NOT connected.

A bit weird...

I am not sure why this, and what is missing.

Any experts out there on the cooling system?
