Tempurture Sensor

I have a 89 GMC 7000 series Dump truck with a 366 engine carburated.
I am tring to find the temperture sensor on this engine, all I found was the temperture switch located where I thought the sensor should be at the intake manifold where the inlet radiator hose is. My temperture guage does not move at all the needle is at the left side of the guage and I want to start with the sensor first.

you might check on the cylinder head just above the exhaust manifold, usually you can test the guage by grounding the sending unit wire out and the guage should sweep all the way hot.

I agree with bejay, look close to the bell housing above the exhaust manifold.
