When it runs, a car engine produces a lot of heat and must be continuously cooled to avoid damage to the engine. 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. How the coolant circulates A water-cooled cooling system A water-cooled engine block and cylinder head have interconnected coolant channels running through them. Read: WHAT IS AN ENGINE BLOCK? At the top of the cylinder head, all the channels converge to a single outlet. A pump, driven by a pulley and belt from the crankshaft, Drives hot coolant out of the engine to the radiator Which is a form … Continue reading How an engine cooling system works
