I purchased “flush” kits for winterization as I was informed that “ear-muffs” would not provide sufficient cooling to block. I have 5.7litre Volvo pentas with I/O’s.
You can also add antifreeze through winterization kit easily via container and valve system. The jury is out as to which is the best way to winterize – drain or flush with antifreeze, leaving the antifreeze in the block and risers/manifolds.
Next dilemma is now from what I’ve read and watched on Youtube is that you require engine antifreeze and not plumbing antifreeze. Plumbing antifreeze doesn’t carry rust inhibitors, but this isn’t clearly defined. I would also think this to be true for the genset also, but not necessarily the air conditioning unit.
Any additional experiences, information would be appreciated on this subject.
