Antifreeze Winterizing 2007 Outback by Deerfield
Finished the collector today. Used PVC pieces to create a means of capturing (without a mess) and recirculating antifreeze through the engine. Tomorrow I will adapt a feeder line from a capture tank (probably a twenty gallon bucket positioned under the collector end) to the raw water impeller. By letting the engine idle and come up to operating temperature I hope to also get antifreeze through the lines and core of the heater. Also will change oil and filter. Have not made up my mind whether to pull the engine block drain plugs and empty lines, or leave everything intact for the winter. Will post more pics tomorrow.
Why go through all of this trouble?
Why are you going to all of this trouble? Indmar's instructions for winterizing the engine are to drain the block and manifolds and leave the plugs out. I do that plus drain the shower and heater, lubricate the threads so that they will not rust and have never had any problems. I get 2 or 3 good freezes each winter and store the boat outside. Not only is it just as fast if you are doing a total winterization but you do not have to dispose of any anti freeze. Even if it is biodegradable you can't just dump it into the lake.
