Good plan to have it towed. Not having heat can be a problem in that weather, but a bigger risk is losing more coolant and the engine overheating, with consequential damage to the cylinder head.

Someone will post that you are supposed to use a flatdeck. Nothing wrong with a wheel lift as long as the rear wheels are on a dolly, as shown.

Should be covered fine. Not an uncommon problem. Good luck.
