Thermostat again? Tempeture sensor maybe bad....

You have trapped air in the cooling system, purge the air out of the system. You can do this by raising the car front end as high as possible and filling the coolant recovery tank to the brim leave the cap off, then run engine until it reaches operating temperature, then shut it down and run cold water over the radiator core, the coolant tank will be sucked dry most likely as the air is purged and replaced by coolant.

My computer is appear " The System BIOS has detected that your notebook PC was not into hibernation or shutdown to avoid overheating.The system is now operating normally.
Overheating may occur if the cooling vents are blocked or the operating temperature exceeds the specification.The notebook PC should return to normal operation once the situation is resolved."
System temperature (90D)

Where do you live?
This has been a hot summer, bit hotter than usual due to the solar flares going on...
as long as the pointer stays within normal operating range, you must not worry... especially since you changed the thermostat and did a flush, did you make sure you got the right temperature range thermostat installed, rarely but few times that seems to be the problem, hotter thermostat gets installed by mistake.

well your CPU centeral processing unit is overheating ..check the fan if its still working.. if its then try to clean the fan take it part and get it clean .

Your English is very good.

From what you have described, which is a rapid over heating of the radiator coolant fluid and therefore a hot engine condition, it would appear that the thermostat in the engine's cooling system is faulty.

If the thermostat is sticking in the closed or nearly closed position temporarily, there will be no flow or very little coolant flow between the engine and the radiator and the engine will overheat.

You have advised that after the engine is shut off , and radiator coolant fluid has cooled, you re-start the engine and drive the car without the overheating condition occurring again and the radiator coolant temperature is normal. This time there is no overheating because the thermostat is working normally.

You should have the thermostat replaced as soon as possible because allowing the engine to overheat can cause very expensive engine damage.

If you had a continuing overheating condition then I would suspect both the thermostat and the water pump. However as the overheating seems to be only temporary, and clears itself after you have shut down the engine and re-started it 10 minutes later (without further overheating arising) then I think you only have a faulty thermostat.

Please also check that the electric fans which draw air through the radiator are operating. These run on a temperature sensor and will switch on automatically once the radiator coolant fluid reaches a certain temperature and then switch off again when the fluid temperature reduces. You will hear them running once they start up. If these fans are not working the radiator coolant can quickly overheat in various driving and temperature conditions because there will be insufficient air flow through the radiator to cool the fluid. If the temperature sensor is faulty or has died, or if the electric motors running the fans are faulty, the fans will not operate.

I hope this helps.

Hello... You should not be concerned... This is normal... Also, normally you should not hear the thermostat. But the Fans don't normally turn on until about 100 degrees centigrade....

Good Luck

You have a broken defrost part. Either the heater, t-stat or timer. The longer you let it go without repairing it, the more parts is take out.

Hi,

Pls check the thermostat. It is most likely a sticking or even stucked as that is basically its purpose, to restrict the coolant flow and allow the engine to reach operating temperature thereafter grant free flow of the coolant. It would seem that there is considerable delay in its opening and therefore the temperature rises above the normal operating temperature.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
