Why Isn't Water an Acceptable Substitute for Antifreeze?

Although water can be used for a very short time when antifreeze isn't available, it isn't a good long term substitute.

Antifreeze also contains lubricants that are designed to help the water pump as well as anti-foaming agents. In most cases, a 50/50 mixture is recommended for nearly all passenger vehicles.
