Newbie to A4 here, appreciate all the insights.
After digging through all the diagrams, manuals (Original, Westerbeke & Moyer) I am still a bit unclear on a drain plug location........
Winterization - COOLING SYSTEM
Step 2: Remove the two drain plugs in the side of the block behind the starter and alternator, and the single plug in the rear of the exhaust/intake manifold.
- Plug on Exhaust manifold - Got it,
- Aft drain plug behind starter/alternator - Got it (simple as drain tube attached),
- Second plug behind starter/alternator - ummmm where exactly ?
I see a larger (1/2 in) brass plug just aft of the flywheel cover inboard of the starter which looks like the same height as the aft drain plug but seems larger than expected...... just visible in attached photo.
I suspect that's it but without clear guidance the newbie was hesitant to start removing block plug bolts...
Insights ?
Instructional diagram perhaps?
And considering my boat is 3 hrs away....the associated question of if I drained the system by the other two plugs and opening the water pump/impeller cover am I at low/medium/high risk of freeze damage if it did freeze hard before I got back to her ?
I suspect I can take a deep breath till I get back up there in a few weeks, because for good or bad, Marina ethic here is to drain without antifreeze application. Boat will spend the winter in the slip where the fresh water never freezes with a small heater running on board. PO never even drained engine, just ran the heater which I am uncomfortable with as shore power can be sketchy in the winter.
Call me overly cautious but the A4 is a recent Moyer rebuild so I don't want to mess it up.
Thanks for the thoughts, CnC for me
