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
1) Hot air is not hot
The most overlooked phenomenon caused by lack of flow. Engine water
in winter
After warming up,
The hot wind cannot blow out, and inexperienced people even think
that
The car is dead, it's time for a replacement. In fact, just replace
a small water pump.
All can solve the problem.
2) 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.
3) The cooling water is reduced, the large circulation is not
smooth, and the engine is high temperature:
At this point, the pump has been relatively serious damage. If you
continue
Driving will directly lead to increased engine damage.
