    I have the 89 celebrity 6 cyl efi multiport. I have changed the radiator cap. what thermostat are you talking about that could be upside down? I have fllushed the radiator and the temp light still comes on after 5 min and the engine dies after 10 or 15. I can stick my finger in the coolant. its not hot

  • dean petersen Mar 16, 2011

    DUH! I should have known that! will check it out tomorrow,,,time for bed!

  • dean petersen Mar 20, 2011

    I have changed the air filter, the radiator cap, the thermostat and flushed the cooling system. Stil after ten minutes driving/idling the temp light comes on and after 15 miutes or so, it dies. I have to wait 20-30 minutes til it cools off, then starts immediately. Have been told could be an electronic connection in the control module that heats up, breaks connection then cools down and reconnects. How in hell are you going to find that and are there any other possible causes?!!!

    I have changed the air filter, the radiator cap, the thermosstat and flushed the radiator...still the temp light comes on after 10 minutes and car dies after 15 min or so...at least now, the radiator coolant is definitely hot ( was not before I changed the thermostat).. The temp light has been coming on for nearly a year but, has not started dieing until recently. Someone mentioned that it might be an electrical connection, maybe in the control module (which I have no idea where it is) that gets hot and loses contact then, after 20-30 minutes, cools down and reconnects. Damn! how do you find that?! HELP!

  • dean petersen Mar 22, 2011

    I really appreciate your help I was no aware that I posted you as non-helpful. You were. What can iI do to post a positive comment for you? Thanx

  • dean petersen Mar 23, 2011

    This is all bulls^^ ! my radiator is cool, my engine is hot the temp light comes on the heater is hot in 5 min there is no circulation of the coolant. I have flushed the coolant and replaced the thermostat and the radiator cap. The water pump is turning and I can find no leaks'.. Is there an electronic connection that heats up, breaks, then reconnects after cool down? If so, how do I find it?

    The crankshaft position sensor on a 1988 Chevrolet Celebrity 2.8 liter engine (VIN W) is located in the middle of the engine block on the rear side of the engine (as mounted in the vehicle). It inserts into a hole in a surface that comes out at about 45 degrees from the engine block facing upward and to the rear. It is held in by one bolt that should be torqued to 8 Newton meters (71 pound inches). As mounted, the bolt is to the left of the sensor. On a 2.5 liter engine (VIN R), the sensor is attached to the back of a plate that the ignition coils are attached to (the ignition module). This one slides into the engine block in roughly the same place as on the 2.8L, except it slides in horizontally (into the vertical surface of the side of the engine block), not at a 45 degree angle. The module is held onto the engine block with three bolts that should be torqued to 27 Newton meters (20 foot pounds). You'll have to raise the car to access either one.

Hi!
I need a more specific make and model and engine to give you an answer, these are in different locations on different motors.

On a 2.2L engine, the CMP or Camshaft Position Sensor is located on the back of the engine above and to the drivers side of the oil filter. It is under the intake manifold and requires the removal of one bolt to remove it. It will NOT be easy to get to. Hope this helps...

If the coolant is not warm and the temp light comes on I would change the thermostat. That tells me it is not opening and allowing the warm water to circulate, it is staying in the engine, if this was already done make sure that it is not upside down as this can aslo block water flow. If the thermostat is good the the temp sensor is probably bad. You can take the thermostat out and run the car for awhile and see if you still get the temp light, if not then the thermopstat is bad and needs replaced.

    The thermostat is under the water outlet on the top of the engine. The upper radiator hose attaches to the water outlet. Just follow your top radiator hose back to the engine and it will be under the domed cap the hose hooks to. If you didn't recently change it I doubt it is in upside down.But since you don't know about it you might want to change it or remove it for a while since it may be old.

    on the (multiport 2.8) its on the back bottom of the block between the firewall and the motor. If the sensor is old (and it prolly is) it will be brittle and probably break off as you try to remove it. I guess you could spray wd40 or something on it but mine broke off and I had to pay somebody to take off the oilpan and pop it out from the inside. You might be able to do that yourself but if not now ya know what to expect. GOOD LUCK!

    ZHave you checked the water pump action. Is there a good flow going through the radiator while the engine is running? If there is something in the control module, the only real way to test is to put it on a tester machine and when it fails the computer will find out what the failure is. If this is as consistant as as you say it shouln't take long to find. I don't mond helping you in fact I have gone a long way in answering your questions, but they keep changing, and I sse you rated me as non helpful. I believ I was helpful in your questions.
    your original question is as follows.
    where is it and where is the cam sensor. car dies after about 10 min driving or idling always starts 20-30 min later. radiator coolant is barely warm temp light comes on.
    I answered that and continued to work with you , but now I can't get paid. And I am still trying to help. If I am helping you I would appreciate if you could accept my answers if possible. Thanks.

    If you could just use the 4 thumbs up for my solution that would mean a great deal to me . This helps my rating to confidence to other users that I can be helpful to in the future. I am still on our side here and hope we can get this issue fixed for you, this I know is an agravating situation to be in. Your best bet is still to get this car hooked up to a tester so you won't keep trowing good money after bad. If there is anything els I can do to help please let me know. Thanks

    If your not getting a flow through the radiator then whether the pump is turning or not, it is not working! Bottom line! Did you take the thermostat out and run the car like I asked? you should see good flow in the radiator with no thermostat if the pump is working. It may not have time to open and let the coolant flow if it shuts down so soon. I also explaine the only way to catch a circuit that is opening and closing is to either shot gun the sensors, I mean replace all of them or put it on a diagnostic machine. The machine will tell us immediatly what the issue is when it fails.

    I read you statement again and is your engine actually getting hot? did you touch the engine and see how hot it is? or are you going by the temp gauge. If what your telling me is that the engine is actually overheating and radiator is cool, then the only things possible here are the pump and thermostat, no electrical devices opening and closing, no instruments openeing and closing, no wireing opening and closing. Just the pump and thermostat, thats all there is! My guess is the pump is not working if your thermostat is good. But take it out and run it and see what happens. This will not hurt the car, in fact it will help it till you find the issue.

Camshaft sensor problems


If the sensor detects a problem, it sends a trouble code to the ECM and your "check engine" light will come on. IMO, your symptom sounds like "cold engine" issue. Myself, our 98 Toyota Rav4 will idle rough and engine stalls when put in drive, but the problem goes away when temperature shows the engine had warmed up to operating temperature. FYI the temperature sensor monitors the radiator coolant temperature. Normal engine temperature is when coolant reaches 120 degree fahrenheit. At around 130 to 140 degrees fahrenheit, the coolant thermostat opens to let radiator coolant flow from "bypass" mode to "enter radiator" mode. If it takes longer than 10 minutes for your engine to warm up, its possible the coolant thermostat is stuck in open "enter radiator" mode. When thermostat is close, coolant radiator bypass the radiator to speed up engine warm up, but if its stuck in open, it will take longer to warm up the engine. Another factor is ambient temperature. If its cold below 50 fahrenheit, it will take longer to warm up the engine.

Accent 2000 runs well then stalls once hot and will not start till cooled off


Check your coolant level and overflow bottle for proper fill. Or try running it With radiator cap loose to see if it still stalls. If it still stalls and coolant levels are good you need to check temp sensor. May be more than One. If you did install a new one, it may have been faulty or damaged. If all that fails then try an idle positioning sensor. The spring may be worn.

Chevy Malibu Cold Idle Problem


Check the water coolant thermostat. If it is stuck in the "open" position you are heating up all the water in the coolant system and this will take time. The thermostat keeps the water in the engine until warmed up to almost normal running temperature, only then does it allow the coolant to enter the radiator.

Engine dies


Does it have an IATC or idle control valve? Did you remove the battery cable for ten minutes,rehook it up,start it and let it idle for 5 min. and then drive it for 10 or more miles? That will reset the computer to your driving habits they tell me.
Now,cleaning the MAF sensor and installing a new air filter would be a good move.Do this before you unhook the battery to reset the computer.

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.
