What is the reason why the water temperature of Peugeot car rises too fast?

There are many reasons for the high water temperature of automobiles, most of which are caused by water seepage in water pipes and insufficient cooling water. Common ones are: broken fan belt, water leakage in water tank or water pipes, thermostat failure, oil leakage, etc. If the engine power disappears or sounds such as violent knocking and cylinder knocking are turned out when the car is driving, it is mostly because the engine is overheated.

The specific reasons are as follows:

The cooling fan does not turn. The cooling fan may be controlled by a temperature control switch; It may also be controlled by a water temperature sensor.

insufficient cooling medium. (1) antifreeze: high-end cars are required to be filled with antifreeze all year round; ② Water or distilled water: temporary substitution; ③ Water tank cover leaks.

the thermostat is damaged. (1) If you want to remove the thermostat, you should plug the small circulation at this time, so as to ensure that the coolant is completely dissipated by the water tank; (2) when installing a new thermostat, attention should be paid to the water hole, such as Santana, there is no water hole. At this time, a hole should be drilled with a 6mm drill. One function is for marking; Another function is that when the car is heating up, the temperature difference between the two sides of the thermostat will be generated, so that the thermostat can be opened accurately with the water temperature.

the water tank is blocked. ① External blockage should be removed by water or gas; (2) Internal blockage will affect the circulation of cooling liquid and generate pressure at the same time. At this time, there will be two results, one is that the water tank leaks, and the other is that the water temperature is particularly high when driving at high speed.

the water pump is faulty. ① The timing belt is broken due to slipping or sticking of the impeller; ② Impeller deformation.

cylinder erosion. (1) The combustion chamber collides with the waterway, which will drain water or discharge white smoke from the drainage pipe, resulting in frequent water shortage in the water tank; (2) the water channel collides with the oil channel (the oil is white with water); (3) The collision of water channel and water channel causes bad heat dissipation of cylinder block, especially at high speed; ④ Waterway blockage.

Solutions to the high temperature of the automobile water tank:

1. Pull over, put the automatic gear into P gear, put the manual gear into neutral gear, pull the handle of the parking brake and turn off the air conditioner.

2. If you find that the coolant is boiling and overflowing from the radiator after opening the engine cover, please immediately turn off the engine and turn the car key to the on position, and do not start the engine again, so that the electric fan of the radiator can operate automatically to facilitate heat dissipation.

3 cooling height. If the cooling liquid level is low or there is no cooling liquid at all, check whether the upper and lower water pipes and their interfaces are leaking or whether the fan drive belt is broken.
