Its the water the provides the cooling not the antifreeze which does as its name suggests in the winter i.e. stops your water from freezing. Race cars use it for safety reasons together with additive which provides the necessary lubrication cos the glycol is slippy if spilled on the tarmac in a crash. Use de-ionised water though not tap otherwise you get a nasty build up of scale deposits. Obviously before winter drain the system and put the correct water/antifreeze mixture back in.
