Automobiles water pump parts and their importance
Purpose of the water pump in vehicles
Water pumps in the car are meant to push coolant through the car’s engine block, radiator and hoses to get the engine heat away from the system. The water pumps are driven from the crankshaft pulley or the crankshaft itself. The coolant that gathers between the impeller blades travels outward using centrifugal force, and suction draws the coolant into the water pump from the radiator.
After the coolant enters the water pump, it goes through the whole engine, where it absorbs the heat that the combustion process produces, and then it goes to the radiator, so the heat can exit to the outside air. If the car’s water pump is not working, the most common reasons come from contamination in the fluid, high levels of vibration or a lack of balance in the load.
How does car cooling system work?
Following parts are the constituents of car cooling system. And they work as explained.
Head Cooling: Coolant moves through passages cooling the cylinder head
Block Cooling: Coolant moves through passages cooling the block.
Thermostat: Depending on the temperature of the coolant, it sends liquid through engine passages or to the radiator to be cooled
Water Pump: Moves cooled liquid through the engine and hot fluid through the radiator to be cooled
Cooling Fan: Helps cool the liquid moving through the radiator
Radiator: Cools the liquid to be redistributed throughout the engine by the water pump.
Causes for the coolant pump or water pump damage may be due to mechanical aspects like the loose/broken impeller, faulty bearing/seal, and damaged drive wheel; Cross – section reduction to corrosion or sealant; damage to the impeller due to the formation and collapse of vapor bubbles in the coolant; electrical fault. So be attentive to these problems in your vehicle water pumps otherwise your car engine may seize.
