[urq] Disappearing Coolant

[Brandon Rogers]

Guys-
I have a magical cooling system.  It makes coolant disappear without a trace...

I've been havign to add a few cups every several weeks.  Have not seen any drips after shutdown or while idling hot after driving.  I've had friends (Audi enthusiast friends) drive behind me and although I didn't ask them to look for smoke they are the kind of people who would have noticed and said something.  Don't really see any residue either.  Recently replaced the overflow tank cap as I thought it was the culprit before.

Any more ideas greatly appreciated.
