[Vwdiesel] Fw: Cooling system flushing

[Tony and Lillie]

Your stuff must be more reliable that mine. In the last year, I've changed 
it on the Jetta and two of the 4000Q's due to fixing leaks. The Jetta was a 
freeze plug heater (which I threw out) and one 4000 was the radiator, the 
other was the expansion tank.
