OK, as a self-anointed semanticist I'm going to jump in here. Technically,
'coolant' would be whatever you put in an
engine's temperature moderating system. It could be water, water + soluble
oil, water + WW, alcohol (old school) +
water, 'antifreeze' + water, etc . 'Antifreeze' would be an agent added to
coolant to lower the freezing point of the
coolant so, technically alcohol, store-bought 'antifreeze'--which, typically,
is either (mostly) ethylene glycol or
(mostly) propylene glycol (kinder to animals and the environment,
supposedly)--or something BMW sells for twice the
price but is likely just ethylene or propylene glycol with a BMW logo which, of
course, adds great value to the liquid.
The stuff that's sold as 'waterless' coolant is, I believe a mixture of both
propylene and ethylene glycol. Antifreeze
also contains rust inhibitors and/or pH moderators; aka 'buffers.'
So, technically, if you put only pure antifreeze in your radiator it would also
be the 'coolant.'
