I have the Moyer FWC cooling system on my A4 which needs no
winterization (as it and the block are filled with automotive type
antifreeze). To winterize the seawater side of the FWC, seawater pump
and wet exhaust I pull a hose off the seawater strainer, put it in a
bucket of the pink stuff (non toxic RV/marine engine anti-freeze) and
run about 3 gallons through until pink starts coming out the exhaust
pipe. Prestone protects the freshwater side, pink stuff the seawater
side. I also squirt some MMO in the combustion chambers through the
spark plug holes to keep the rings/valves free during the winter and
to dissolve any build up on them from the season. The Moyer site has
a couple of write ups on winterizing in the forums area.

When I first put fresh water cooling on my A4, I did drain the
block and pump every year, but then it occurred to me that I was
leaving the interior of the engine filled with air and moisture, not
the best combination. Taking the side plate off in my case would be
difficult. I now make sure my coolant has antifreeze (the automotive
type) that protects down to minus whatever, and leave the block full.
My thinking is that the coolant has a corrosion inhibitor in it,
probably better for the engine. Am I missing something?

When I bought Touche' in 1999, it had an AT4. It had the drain
plug extension. When I finally got it started, the drain plug
extension leaked. As I recall, it was corroded at the threads at the
cap. When I went to replace it, it fell apart. I think it's just a
1/8 or 1/4 pipe nipple. Just something to check and be aware of.

I have the extension pipe installed between the distributor and the
alternator belt. There is just a cap on the end that I remove to drain
the block. It is easy. The two drain plugs on the block are simple to get
to. The drain plug on the bottom of the water pump is a bit fiddly to
start back in, mainly just an issue getting into the lazerette enough
to reach it. I doubt it is a 5 minute job to do all four.
Is it common to just drain the engine ( block ) and not fill it with
antifreeze?

U have to drain the block. Side inspection plate will leak if you dont
drain it. Its fragile as it is. It doesnt take too much freezing to
develop leaks. Block drain plug is under distributor, just aft of side
inspection plate. It's pita. Moyer sells extention to make this easy.
