Ok so my 89 firebird (5.7 tpi) idles rough and will not start once hot. I was looking over the engine to find the problem. I think it a sensorof sometype. But the problem is where does the wire from it go to? Its attached to the radiator. So if someone will go look at theres and tell me where it goes to it my fix my problem thanks.

 

Oh and I think it might be a temperature sensor, If anyone could please go look at there car to see what it goes to you will be a huge help!

 

It's a low coolant sensor.

 

oh is there suppose to be a wire going from it to somewhere? It looks like it had one at on time. thanks for the reply.
