Will my car freeze without antifreeze?
With no antifreeze or water, there is nothing to freeze so it will be fine to leave it drained of all coolant overnight. If you had antifreeze in there before you started your repair, your motor will be fine. The antifreeze ISN’T so the ENGINE doesn’t freeze, it’s just “winter-grade” coolant.

One common cause of the coolant reservoir being full but the radiator low on coolant is a blown head gasket.
