This is a 97' GLT with 170k on the clock. I changed out the radiator earlier this year and have not had any cooling problems except the fans run all of the time when the car is on and for a brief period after the car is turned off. Right now, the temp outside is quite cool and the car is only being driven short distances yet the fans still run. Any ideas on why and how to fix it?

Thanks,
Zack

 

Did you replace the thermostat when you changed the radiator?
You could also have a bad temp sensor.

 

I'm with tech and betting on a bad coolant temperature sensor. That is what caused the same issue on our 95 Turbo. Is the check engine light on? If so, I bet you have a code 1-2-3 which will point to a bad coolant temperature sensor.

 

No I did not change the thermostat. Sounds like it is the temp sensor though?? The check engine light had been on at one time but is now off. Where is the temp sensor located and how do I access it?

Also, where can I buy a new one? Does anyone have a site or store recommendation? How about a part number?

Autozone has something called an "Electric Fan Thermostat" What is this??

Thanks!

Oreilly Auto also has something called a "Cooling Fan Control" Anyone know what this is?

 

Sorry I don't. Maybe they mean the relay?
I posted the link to the thermostat as well because you will be in there to change the sensor and the thermostat might also be broken.

 

The parts are inexpensive enough to replace both. Where do I find both of them on the car? Are the tough to access? Any special tools required?

 

Follow the upper radiator hose to the motor.That is the thermostat housing. You will need either a T-40 or T-45 I forget exactly which size I have a special socket I use and just grab it. Then sensor you will need a 19MM wrench.
The sensor is kind of a pain but the rest is pretty easy.

 

Do you know where the temperature sensor is located? You said it was PITA and that makes me nervous as I am pretty amateur.

Thanks! You have been so much help!

 

That wire coming out just under where the thermostat is is the sensor.
