The water pump, the coolant pump , is one of the most important elements of the engine cooling system and this method of cooling is commonly called water cooling . The engine block and the engine head are elements that heat up to very high temperatures during operation and it is these that we want to cool with coolant during operation. Special water channels are bored in the engine and the head for the circulation of water, which, in order to be re-injected into the engine water channels. The circulation of the coolant is possible thanks to the water pump , which is most often placed between the radiator and the engine and is driven by a V-belt from the alternator. To the pump flywheel, we screw in the following order the pulley, and then the radiator fan, which rotates together with the pulley, providing the air movement needed to cool the radiator during engine operation.
