I ran the gas out of it in the water before hauling home. Gravity drained water out of it but I didn't flush the cooling system.
I may let the garage freeze when we go on winter vacation and that's where it's now stored ... do I need winterise it / bring it back inside where it won't freeze?
Could there still be water that didn't drain out inside the system? It's been over one year, I never put it in this season.
