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.

Could you possibly direct us to these studies? And remember modern day technology far surpasses many of the faulted studies of yester year.
