Problem: Can't get Fan temp sensor out of engine block!!!

When I installed my headers and Y pipe the other day, I broke the fan temp coolant sensor.. I can't get a wrench to stay on it and sockets won't fit.. It is torqued on their pretty good.. When I try to get a wrench on it, it just slips right off almost as if it were stripped..

The fan is wired so it is always on, so i don't think I really need it other than to monitor my engine temp..

Does that coolant/fan temp sensor have anything to do with the computer, like control anything important?

Is it ok to drive without this for a while?

How much you think a mechanic would charge to replace it?

Thanks

I think if you leave that unhooked, your fan won't come on. I did mine, and got right on it with a deepwell socket. I don't think a mechanic will charge you too much, since he will have the car up in the air on a lift, and it won't be too hard for him to get to. Sorry that I am not much help.
take care & Good luck

I connected the fan relay so that the fan runs all the time. If thats all it does then maybe i'll just wait until I have more time to mess with it. If it does more than just display the temp and turn the fan on, then I'll have to replace it soon.

THanks

92,

There is a socket made specifically to remove the sensor. If you round off the flats too much the special socket may not work either.

There is also a separate coolant temperature sensor that signals the ECM on TBI engines. TPI engines use a CTS at the front of the intake manifold to signal the ECM, and the ECM drives the primary cooling fan. If you have dual fans, the secondary fan is a locally controlled relay with a separate CTS just for that purpose.

Vader,
I don't need a Deep socket for it because it is broken completely off. All thats left is a brass plug with plastic in the center. I bought a 13/16" 6 point socket today, I'll try tommorow to see if I can get it off. The other sensor on top of the intake manifold is fine. Like I said, I have the fans wired to always on so that is not a problem.

Is it OK to drive without the sensor that I broke off? If I can't get it out, I'll just pay a shop to do it along with a front end alignment which I need badly..

Thanks for the help.

The same thing happened to me when I had to change my knock sensor, just get a small 2"-3" pipe wrench on it and it will come out
