How the product works

In the upper water outlet of the engine, there is a water pump, which passes through the belt
to drive, pump out the hot water in the water channel of the engine block, and pump the cold water
enter.
The water pump bearing and impeller are driven to rotate by the pulley, and the
The coolant is driven by the impeller to rotate together, and is thrown away under the action of centrifugal force
to the edge of the pump casing, while generating a certain pressure, and then from the outlet
Outflow from water channel or water pipe. At the center of the impeller, the coolant is thrown out
The pressure is reduced, and the coolant in the water tank is between the pump inlet and the center of the impeller.
Under the action of pressure difference, it is sucked into the impeller through the water pipe to realize the reciproion of the coolant
cycle.

Water pump failure performance

1. Unstable idle speed:
The failure of the water pump can cause the rotational resistance of the water pump to increase.

2. There will be noise in the engine part:
This sound is a rolling friive, similar to the sound of "boom boom boom".
This sound can be accelerated as the engine rotates and changes in volume
change. This noise generally increases with the severity of the fault
increasingly obvious.

3. Cooling system failure

Engine water temperature is unstable:
The performance is that the engine water temperature indior needle fluctuates within a certain range. The reason is
The water temperature in the small cycle is inconsistent due to the lack of circulation. On the one hand, it leads to
The opening temperature of the thermostat increases, on the other hand, after the high temperature water flows out, the low temperature
The water quickly flows to the thermostat, causing the thermostat to close quickly. Under normal conditions
After warming up, the water temperature of the engine will remain at a relatively constant
level, approximately at 93°C.
