I have a 1992 camaro with a single cooling fan. I replaced the coolent temp sensor yesterday because the fan did not work at all and now the fan comes on at 110 degrees.
When I was tightning the sensor I heard something crack. Could I have ruined the new sensor? Also I had to replace the wiring to the sensor( original owner cut it). I wired one wire to the green and white wire and one directly to a ground on the car, Did I wire this up correctly? I believe that it now runs all the time. Please help!!!!!!!!!!

Thanks Jody

the cure-all for fan activation problems & allows you to set the activation temperature wherever you want. I run them on all my cars and never have a problem.
You will need to use a relay with this to supply battery power to your fan.

good luck

If your car is an RS VIN "E", the coolant temp sensor has one yellow wire and one black wire. Green/white wire sounds like fan switch or A/C pressure switch in which case the black wire is to ground. Where is the sensor located that you replaced?

You did wire up the switch correctly to the dark green / white wire - sounds like you need to replace it, again. in a '92 VIN E setup, the fan is controlled by the thermal switch in the passenger side cylinder head (fan on above 238 F), the A/C select switch (fan on when in the "MAX", or "NORM" positions), and a pressure switch (if you have A/C), located on the liquid line (dark green / white & black wires) - (fan on above 232 psig). Grounding the dark green / white wire turns the fan relay on when ignition power is applied.

Matt_Ky, the temperature sensor you are referring to is the coolant temperature sensor for the ECM & does not control the fan in the VIN E configuration.
