I run water and drain in the winter but don't drive when the weather can go anywhere near freezing. I simply add water pump lube/rust inhibitor.
P.S. The "old green" antifreeze probably would be safer though not cooling as well as straight water.

I want to know about the study's, want to add mine to it, always had antifreeze, had to add thermostat because ran too cold, the used head gasket I put in 35 years ago is still fine, have a stock water pump that hasn't dripped for many years ------ ford sold antifreeze at the dealerships
