Winter Storage Questions

This is my first winter with my 655D, 4 cylinder Perkins, and I was wondering if I could get some recommendations for winter storage here in northeast Ohio. I am hoping to get the machine indoors before winter gets here, but if not it may have to sit outside under a tarp this year.

I have read about filling the fuel tanks to reduce condensation, including a fuel stabilizer, but what do I need to do about antifreeze levels or percentages. I don't know if this engine has freeze plugs, but I know its always a concern for cracking an automotive block.

Anything special with the hydraulics?

Thanks!!
