Hey Guys,
My 86 camaro has the electric fan and for watever reason i comes on when the car is about 180 degrees sometimes less. This makes the battery and alternator constantly powering the fan while driving. Before the motor swap it used to run about 220 all the time but now it never makes it close. My thoughts are either the gauge is wrong and the motor is at 250 and my gauge is just telling me incorrectly or the temperature sensor is problematic.
There is a weird little sensor under the driver side exhaust manifold that now has a resistor attached to it in-line, that may have something to do with it?
I tried to buy a new sensor from vatozone but they could not find a replacement...
What should i do?

not an expert here, but i think you can check your gage by grounding the wire to your temp sender and see if it pegs out your gage. never heard of a resistor on the wire before... maybe another trick you could do is verify with a laser thermometer or hook up a mechanical gage to verify. at what temp (according to your gage) is the t-stat opening? your t-stat should be opening before your fan comes on.

It could be a bad gauge or a bad sensor.

One way to test the gage is use one of these. http://www.autozone.com/autozone/par...43_433641_4074_
As long as your not keeping the car stock I don't see why it would not work. Most stores like Autozone have great return polices. If you don't like it or only want to use it once just clean it up and take it back.

They might even rent that... it amounts to the same thing.
