How an engine cooling system works. A car engine produces a lot of heat when it is running, and must be cooled continuously to avoid engine damage. Generally this is done by circulating coolant liquid usually water mixed with an antifreeze solution through special cooling passages. Some engines are cooled by air flowing over finned cylinder casings.
