07 The temperature of the LGMG 953 torque converter is high, up to 140!

There are many reasons for the high water temperature of the engine or even "boiling", such as damage to the electronic components of the cooling system (thermostat, cooling fan), poor heat dissipation of the radiator, insufficient coolant, etc.

Pull over, but don't turn off the engine right away! Because the coolant temperature is already high and the cooling capacity has reached its limit, if the engine is turned off immediately, the boiling coolant will stop circulating (for most engines, the water pump is driven by the crankshaft).

Of course, if it is an electric water pump engine, it will be better), too high temperature is not cooled, the engine is also unbearable. If the engine is left idle for a while, the constant circulation of coolant can still reduce the impact of high temperatures on the engine.

Check for a lack of antifreeze that is causing high engine water temperatures. The circulation of the coolant, whether the circulation is not smooth. Secondly, you can also check that water temperature sensors, water pumps, thermostats, cooling fans, etc., may cause high water temperatures.

If you don't have a strong hands-on ability, you should go to the repair shop for an inspection.

1) The oil level and oil quality of the transmission oil are not within the required range;

2) Serious internal leakage of variable speed pump, pressure reducing valve is too low or gear cylinder leakage;

3) The inner sealing ring of the gearbox and torque converter is damaged, and the turbine group is damaged, resulting in leakage or friction heat;

4) The pipeline or radiator is blocked, and the heat dissipation effect is reduced.

Repair and maintenance methods.

1) Check the oil level through the transmission dipstick, if the oil level is too low, the oil should be replenished.

2) Remove the gearbox oil cooler and oil pipe line, check and clean and put it back.

3) Remove the oil suction filter and the magnet filter element together, check and clean them and put them back in.

4) The heat dissipation capacity of the water tank is poor, and sometimes it will cause high temperature of the engine; In addition, the high operating temperature of the engine will also cause the heat dissipation capacity of the water tank to be insufficient. For this reason, you can first check whether the fan belt is working properly, and then check whether the water tank is dirty, and clean it if necessary; Then the cause of the high temperature of the engine is ruled out.

5) Make the machine work under normal load.

6) Measure the working pressure of the hydraulic pump and compare it with the standard value, if the working pressure is too low, the hydraulic pump can be removed and disassembled for inspection. If the hydraulic pump is seriously worn or damaged, another pump should be replaced and replaced.

7) Measure the torque converter outlet oil pressure and transmission oil pressure and compare them with the standard values. If the torque converter outlet pressure is too high, it can be adjusted to the normal value. If the outlet pressure of the torque converter is too low and the pump pressure and the inlet oil pressure of the torque converter are normal, the torque converter should be removed and the damaged parts should be replaced; If the oil pressure of the gearbox is too low and the inlet oil pressure of the torque converter is normal, the torque converter and gearbox can be removed and disassembled, and the damaged parts can be replaced.

I think so, the gearbox is generally not running on the road under normal use conditions, the temperature is about 100, it is normal, if it does reach 120, then I may be working pump oil, and there is a gearbox you said is slow, you should clean the transmission oil pan, change the torque oil filter, and then add regular transmission oil, or temporary special oil, it can be no big problem! Welcome to join the Engineering Home team! The address of the team is Adopt.

It is normal for the torque converter oil temperature to reach 100 degrees in this season, and it is recommended to clean the radiator frequently and check the oil level.

Idle low, turn up a little higher. The black smoke is poor atomization when the fuel injector accelerates sharply. Remove the air filter and try it, if the smoke is reduced, replace the air filter. The air filter element should be blown with compressed air every 16 hours of work, and the pressure should not be too high for 3 kg of pressure, which is too high and easy to break the filter element.

Lack of antifreeze, add antifreeze, check if the fan is working.

This should be caused by the lack of antifreeze in the vehicle, it is recommended to replenish it in time!

Check if it is caused by a lack of antifreeze, and if it is missing, replenish it in time.

Hello, it is advisable to check if there is a problem with the water temperature sensor and if there is a leak in the antifreeze.

Check to see if the coolant is missing and if the thermostat is suitable.

Is there a lack of antifreeze? Check it out and take a look.

Generally, the sealing ring leaks oil, and the problem is solved.

A little expression of ignorance.

Is the outside of the radiator blocked by poplar catkins?

1. Check whether the oil tank and oil cooler are too dirty. 2 Check whether the hydraulic transmission oil is missing. 3 Check whether the hydraulic transmission oil has deteriorated.

4. Whether the car works for a long time and with a large load. 5 Check if the oil temperature is really above the limit. 6. Check whether the clutch and brake pads are slipping, etc., and overhaul the torque converter.

Check that the filter element is blocked, and try to change the oil with new one.

It doesn't matter how long you leave it, whether it's normal before you park.

Try turning up the pressure when you warm up.
