Winterizing- need to fill with anti freeze?

[Dom08]

Ive been searching on the forums here for winterizing. I will be storing my outback outside for the winter under cover. I see alot of people drain the manifolds and so on of water. Is filling the system with anti freeze necessary? Or just drain and call it a day?
I also bought some engine fogging oil. Would this be worth it to do??

If you get a compete and proper drain, there is nothing to freeze.

I filled mine. Cheap insurance.

Just suck it in though the water pump and recirculate it from the exhaust output?

Yes, you'll need a bucket with a spigot, and a fake a lake, and set it on the swim step. Rev the engine a bit. It will suck 6-ish gallons up in less than a minute.

What about engine fog? Good to do also?

Someone else will have to answer that for sure. I bought some fogging oil, then someone said not to fog if you have catalytic converters, so I didn't fog mine.

The cats would be my concern as well. Not 100% sure how the cats will react to the fogging oil.

I recall reading about no fogging in the CAT motor because of a sensor issue.

It's posted somewhere on here.

My outback is 2003.
If we dont use fog should we do anything to protect the cylinders?


For sucking in antifreeze i can just hook the hose up to the water pump and put the other end in the bucket and suck it in? And recirculate it from out exhaust
