Water Pump 236-1307010-A3 is used in the cooling systems of YaMZ-236 and YaMZ-238 engines and is designed to provide forced circulation of coolant through the engine cooling jacket, radiator, and cab heater. Proper operation of the water pump maintains the correct engine operating temperature, prevents overheating, and helps extend engine service life.
The pump is mounted at the front of the engine and is driven by a belt. During operation, it continuously circulates coolant through the cooling system, ensuring efficient heat dissipation from the engine block and cylinder heads. The pump consists of a housing, impeller, shaft, bearing assembly, mechanical seal, and pulley hub, all designed for long-term operation under high temperatures and continuous loads.
When servicing the cooling system, it is recommended to inspect the drive belt, pulley, hoses, thermostats, and gaskets. Common signs of a faulty water pump include coolant leakage from the drain hole, excessive bearing noise, shaft play, or reduced cooling efficiency.
Water Pump 236-1307010-A3 is used on HTZ tractors, as well as trucks, combines, construction equipment, and other machinery equipped with YaMZ-236 and YaMZ-238 engines.
