SOURCE: is there a thermostat shut off switch . car runs

The amount that it gets hot is a clue but theres no shut off switch. It's possible that the car is over heating and the temp gauge does'nt have enought water over it to report the problem. once the cooling system is cleared as it's full circulating and the fan will come on when it's hot ( disconnect the temp. switch on the therostate cover on the top of the transmission, ( the stat is in the lower hose ) with it disconnected and the key on the fan should be on and connected f till it's real hot. The crank senser or distrubutor module can can too hot and shut down too

Air runs until car runs a distance and engine is shut down. when restart air is not cool?


Well of course not. When you shut the car down, all water circulation stops so engine heat goes way up. This means the radiator gets hot too, and therefore so does the AC condensor. It takes time for all these things to cool back down when you start it back up.

1988 Olds cutlass Cierra will not start after you shut it off


When the failure occurs what do you lose, Fuel or Spark? A few ideas come to mind, the distributor, oil sending unit, or a fault at or inside the fuse-box. Your description is very detailed and it looks like you have invested some time into this repair. Hang in there, you a narrowing down your search with each inspection and repair. Write back anytime, good luck.

Run fault codes as I suspect the ambient air temp sensor may be at fault. Night air is predominantly cooler and more dense so something /sensor is altering the air/fuel ratio to run lean. Check MAP/MAF sensors

Check both the crank position sensor and the camshaft position sensor! Heat will affect them as well, causing it to shut down! if the computer isn't getting a signal it can't operate the ignition! Also check map and/or maf sensors

Car runs great until it get about 180 degrees andthen shuts off let it cool off a lil bit its starts back up until it shuts off again why


I am thinking that perhaps the temperature sensor is reading wrong and therefore sending a message to the computer that the car is running too hot. This can happen, my VW presently reads 20 hotter on the guage than a heat gun records at the temp sensor location on the head. If you have access to a heat gun it might be a good idea to check out the actual temperature, but it probably won't hurt to change the sensor.

The other problem that occurs to me is the oil sending sensor. While a temperature sensor won't shut an engine down, the oil sender can. If it is reading a large drop in oil pressure it will shut the engine off. Since oil gets thinner as it gets hot, perhaps a defective sending unit is reading it as too low. Once the oil cools off, it would restart until the temperature gets too high again. I would think that upgrading to a heavier oil might cure the problem. I don't know what you are currently usung but certainly you could go to 10W30 or 10W40 without too much trouble, at least for a test. Hope this helps.

93 seville sts runs great and then after driving wont star fot 30 min to an hr. any easy solutions?


If/when you do get it started, do you have to hold the petal to the floor or give it a lot of gas to 'clear' it up again? Does it smoke when you first start it up? If so, you might have a leaking injector (s), the o-rings allow pressure to push gas into cylinders when you shut down, flooding the cylinder-will cause hard starting. If this is not the case, consider a heat-sink kind of situation with the crank sensor-it gets hot with normal driving, and gets even hotter with heat-soak when shut down and changes electrical properties (specifically resistance) until it cools down again. change the crank sensor.

Sounds like you have have a crankshaft senor problem. Sometime they will go "open" or stop reading when they get hot and after cooling down will start back reading. This is caused by the resistance in the sensor getting too high when it gets hot, resistance rises with heat. Running the air and electronic systems like cruise and radio can cause the engine to run warmer due to extra load on the altenator, ac compressor running, ect ect.

Eletric fan stays on after ignition is shut off


If this is running for a few minutes after shut down, this is normal. If it continues to run long after that there is an issue with the CTS (Coolant Temperature Sensor) circuit or its controlling relay.

Car shuts off while driving wont start up until cools off engine not running hot 99 pontiac grand prix


You need to replace your crankshaft position sensor located by the harmonic balacer. These sensors heat up and cut off the engine until the sensor cools down. This happens with age and it is not specific to GM.

Check MAP sensor. If PCM gets wrong data from MAP sensor it should offset ignition timing and/or make fuel mixture too lean or too rich.
