Radiator fan runs full speed after engine shut down, temp gauge stays cold…unhook battery to turn off…condition is intermittent. ---

You don’t say where you live, but if you have been driving hard enough for the fan to come on, but turn off your car mid-cycle, many cars will keep the fan going a few more minutes until the temp sensor says things have cooled. Time how long the fan stays on. Does the fan start up before the engine is warm? ---

The fan comes on while I am on short trump as going into the city, only about 3 miles…and it seems to be running at high speed. When this happens, the temp gauge is not working with the needle all the way to the left which is cold. I do not know if the fan triggers the temp gauge to quit, or if the temp gauge causes the fan to go full speed. The fan will not turn off even 30 minutes after the engine is shut off. ---

I believe you need a cooling fan controller. Look on YouTube. This comes with a sensor that measures your radiator temperature, and if it is too hot, it turns the fan on (and off when the temp falls!) Your fan is running too much, so it is overcooling. The gauge you read is staying at the cold end. Most importantly, this is bad for the engine, so get it fixed right away. Wait long enough to have a few others agree with me here. Good news: cheap repair. ---

I suspect a faulty temperature sensor. The gauge isn’t receiving a signal and the fan is running in failure mode. ---

thank you for help…besides you suspect a faulty temperature sensor… Others…faulty cooling fan control mod, faulty ECM, and THERMOSTAT sticking open… I appreciate your help. ---

The fan starts sometime after the engine starts, I do not know it is running until I shut the engine off. And it will run until I take battery power away from it. ---

To be fair, I’m not a mechanic but a faulty temperature sensor seems like it might cause both the fan to run and the temperature gauge to stop working correctly. I’m inclined to doubt the thermostat because even if it were stuck open the engine would eventually warm up enough to register, at least a little. I don’t know if a bad fan controller would affect the temperature gauge but again I doubt it. Even if I’m wrong, which is absolutely possible, I hope you can see my logic (or lack of logic). ---

Thanking everyone who helped diagnose the problem… ---

I don’t think the temp gauge is defective. If the fan is running constantly in cold weather, the temp gauge SHOULD say the engine is cold. ---

Good evening…where is the temperature sensor located on this 3.6 engine? ---

Start with reading the faults in the PCM. A coolant temperature circuit fault will illuminate the check engine light however there are other cooling system faults that may not require the check engine light to be on. A thermostat fault for example may not illuminate the check engine light but operating in default may switch on the cooling fan and disable the temperature gauge. ---

Go to RockAuto. When you enter your car’s data, you will be able to see actual pictures of the parts. There are two different styles for you car. One of them has a probe sitting in the fins of the radiator. The other connects into the coolant, but I don’t know where. I always try YouTube to see what others have done.
