Check the working condition of the mechanical water pump

Open the radiator nozzle cover to allow the engine to accelerate slowly; Observe the circulation of cooling water in the filling port; If it continues to speed up, the impeller does not slip, the water pump does not work properly, on the contrary, the water pump has a problem, when it is not easy to observe the circulation of cooling water from the water inlet, another method can be used: let the engine turn off when the water temperature is high, and quickly remove the hose of the automobile cylinder head leading to the water chamber joint of the radiator, you can plug the water chamber joint with a cloth ball, and fill the cooling water into the radiator from the water port. Then start the engine, such as the water in the water jacket of the cylinder and the radiator, and the impeller will not slip about 200ml outside the hose mouth pumped out by the water pump, indicating that the water pump is working normally; Otherwise, it is abnormal.

How to tell if a mechanical water pump is broken

To determine whether the car water pump is broken, you can observe and check it from the following aspects:

1. Listen to the sound

Abnormal noise: If the water pump makes abnormal noise or friction sound during the operation of the car, such as the abnormal sound of "oooo

This sound usually becomes more and more noticeable as the malfunction gets worse.

Check for leaks

Coolant leaks: If you notice a frequent decrease in coolant or a leak near the pump, check the pump's seals for damage. Leaks can cause a lack of coolant, which in turn can affect the engine

cooling.

Look at the water temperature

High water temperature: If the car's water temperature is often too high and the situation does not improve significantly after rinsing the radiator with cold water, it may be due to poor coolant circulation due to a faulty water pump. In addition, the engine water temperature indicator needle fluctuates within a certain range, which can also be the instability of the cooling system caused by a water pump problem. Fourth, look at the instrument

Water temperature warning light: If the warning light on your car's dashboard shows that the water temperature is too high, you should stop and check it immediately, as it could be a sign that the water pump or other cooling system component is malfunctioning.

5. Check the belt pump belt: If the pump belt is worn, loose or broken, the pump may not work properly. Therefore, the condition of the pump belt should be checked regularly and the damaged belt should be replaced in time. 6. Check the shaft and bearing

Pump shafts and bearings: If the pump shafts and bearings are worn and corroded, the performance and life of the pump may be affected. During sound inspection, the degree of wear and corrosion of these parts should be closed, and timely replacement or repair should be carried out.

To sum up, by listening to the sound, checking the leakage, looking at the water temperature, looking at the instrument, checking the belt, checking the shaft and bearing, etc., you can preliminarily judge whether the car water pump is broken. If a problem is found with the water pump, it should be repaired or replaced in time to ensure the normal operation of the car and the safety of the engine.
