Water pump / Mitsubishi S3L2 / Startrac 263 / Startrac 273 / 39205368

Water pump for Startrac tractors of the Startrac 263 , Startrac 273 series with engines Mitsubishi S3L2 series and others .

The water pump, radiator coolant 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 engine head are elements that heat up to very high temperatures during operation and we want to cool them with coolant during operation. Special water channels are hollowed out in the engine and head to circulate water, which is to be pumped back into the engine water channels. The circulation of the coolant is possible thanks to the water pump , which is usually located between the radiator and the engine and is driven by a V-belt from the alternator. Screw the pulley to the flywheel of the pump in sequence, and then the radiator fan, which rotates together with the pulley, providing air movement needed to cool the radiator while the engine is running.

The most common water pump problems and faults are bearing seizure , which is subjected to high rotational speeds, and because the elements that work directly with the pump, such as the pulley and fan, are not always properly balanced. A belt that is too tight , a worn belt , a V-belt that is too loosely tensioned , a V-belt installed at the wrong angle , poor lubrication or lack of lubricant are other causes that cause water pump damage. The first signs of damage to the water pump or signs of improper operation include an unnatural sound from under the hood, a splash of coolant under the tractor or temperature jumps visible on the dashboard gauges.
