Vehicle failure: the engine is high temperature, and it is preliminarily judged that water leakage leads to water shortage and high temperature.
On the 25th of last month, the engine of this car suddenly turned off while waiting for the red light, and then it was started twice without success. After stopping for more than ten minutes, the vehicle started successfully again and stopped suddenly after driving less than 2 kilometers.
The last inspection was that the water tank burst and leaked, and this time it was leaking, short of water and high temperature.
The life of this old Excelle was really hard, and the high temperature caused the engine to stall several times.
The location of engine water leakage this time is probably at the timing belt. Brother Pang suspects that the water pump is leaking. Excelle's water pump is located inside the instrument housing, and the timing part needs to be removed.
The position with your finger is the water pump.
There are many traces of water leakage around the pump.
Remove the water pump.
There was no water when the pump was dismantled, and a little water flowed out after the pump was dismantled.
The water pump has completely rusted and corroded. Look at the place where the edge looks like a dog bite. The sealing ring is almost falling off.
The impeller is not bad, there is not much rust.
There is a small hole next to the pump.
Look at the sky, completely transparent. Judging from the trace, this small hole is the biggest water leakage point.
Brother Pang poked a hole with a screwdriver.
Bought a new water pump.
Contrast between old and new.
The installation step was omitted by Brother Pang. ......
After installing the water pump, align the timing. Then add water, start the vehicle, and observe the start and stop of the electronic fan twice. Finally, check whether there is water leakage at the water pump.
Fat brother concluded: 16-year-old old excelle, I hope not to get angry again next time. After this repair, don't replenish water at both ends for three days.
