Hi
Thanks all for input.
I found a suitable tank http://www.evwparts.com/vwparts/025121403A.html
Not OEM or aluminum. But goes in and works the same.
I am draining oil and carefully inspect the air filter.
Question -- Is it smart to flush the coolant system before adding new
antifreeze mix?
Flush with fresh? Motor Running?
