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. Ken

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 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. Dennis C.

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? Michael Brown Windburn C&C 30-1 From: "phorvati ." 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. _______________________________________________ This list is supported by the generous donations of our members.
