Water tank leakage causes excavator water temperature high alarm

A customer from ChangzhouCAT 320cThere is a frequent alarm when the water temperature is high, and the fault symptoms are as follows:

1. The water temperature is high, and all other actions are normal.
2. After removing the thermostat, the water temperature is basically normal.
3. After replacing the water pump for 30 hours, a high water temperature alarm appeared again.
4. The attached water tank has experienced water overturning.

Cause analysis:

1. Due to the previous replacement of the water pump and EGR cooler, the possibility of these component failures has been ruled out.
·Is there any blockage in the water tank
·Is there any leakage in the water tank and its related pipelines
·Engine main body malfunction
Prepare on-site to confirm the above situation.

resolvent:

1. After arriving at the scene, it was found that the machine had a phenomenon of water tank overturning, so it was inferred that the water tank may be blocked and the water tank cover may be leaking.
2. The water tank was cleaned on site and no blockages or leaks were found in the water tank and its pipes.
3. When checking the water tank cover, it was found that there was leakage. Due to the lack of replacement parts, it was repaired on site to prevent leakage before being installed. After a day of testing and observation, the fault was eliminated and the water tank no longer overflowed.
