Winterizing ... plugs question ...

Following Petes recommendations I simplified this year. I ran seafoam through system, filled tank with non ethanol (as usual) with seafaom added. Fogged down carb till stalled. Changed oil.(20w 50 vr) Drained all plugs and diconnected a few low points on intake hoses to drain, and removed strainer basket/container. I left the impellor in and filled above and below with antifreeze, and dumped antifreeze through t-stat housing till full. re-installed t-stat. charged and disconnected the battery but left in. Spring should be reconnect batttery and start.

a bit baffled but it does say that.

here is the easiest explanation for winterizing

drain water, if you like fill with antifreeze

Here it is Eric,6th one down.

I saw it on a post here that I Searched under Winterize Checklist. The Poster was NAUTI84.

It didn't make sense to me, I've never done that, which is why I asked.

He also said to remove the water pump and remove Impeller. I actually do that, I store my pump in the garage where it won't freeze and I remove the impeller to inspect, or to replace the next year (I replace every 3 years) and to keep it from getting a set over the winter.

Thanks. Cheers, John

why do some recommend only hand tighten spark plugs and leaving the cables loose over the winter ?
how important is it to torque the plugs and not just tighten them up 1/2 turn or so with wrench ?
thanks, cheers, John
