Question about Cars & Trucks
Yes their is a thermostat on this brillant car ,for the size of its engine compared to the american monsters this thing will run them off the road because it does 100mpg over 100mph and stick to the road around bends like a limpet .well its italian what else do you expect ,pity the eyties can only make tanks with one foreward gear and 12 reverse but we will not go their anymore 60 yrs after the event ,right follow the top hose back from the rad to the engine and their is a housing and in this housing is the thermostat ,take it out and put it in pot on the cooker with water in and boil the water and see if the thermostat open if doesnt then renew it if it does open then you may need a new radiator or maybe a new head gasket

ok, its time for a radiator flush. there is major sludge in the internals of this radiator. Make sure the thermostat is in the correct position as well. I've seen many cars come into my shop with the thermostat inserted backwards.

This makes sense to me. The computer would send extra fuel to the engine on start up when it sensed it was cold, replacing the old choke system. The cooling fans turning on when you turn the key would tell the computer that the engine was, in fact too hot, and it would not compensate for the cold start up.
If you unplug the heat sensor how does it start? Check the battery voltage. A good battery should read in the area of 13.5 to 14 volts. Start the car and shut it off and re-read the battery voltage. If it doesn't drop any more than 1 volt there's nothing wrong with your battery. You could also go to a shop and get it "load tested" which would be a better test for sure.
If it starts properly with the heat sensor unplugged and the battery checks out, I'd replace the sensor first. It's possible that there is more than one problem contributing to your hard start but you will have to start with what you know for sure is wrong. Hope this helps.

SOURCE: Hello... I got problem with
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.

Do you have the error code (P0742 = torque converter clutch stuck on...locked and P0741 TCC stuck off). The TCC solenoid replacement for the 4T40E (and 4T45E) is not very expensive but the job of getting the transmission case out from the car is difficult. Unless you have experience of fixing transmissions this is best left to an expert.
