Stupid question. Where is the coolant temperature sending unit at on the engine? 73 c20 350/350. Guage usually reads low. Today it showed normal operating temp. That worried me so I went and bought a laser thermometer. The highest temp I can find on the block is 210. exhaust manifold peaked at around 400. Anyway new sensor was $10 bucks. I know it's an ass backwards way of doing things but I'm gonna change it out if I can find it. Not in chiltons that I saw.

On my 79 it is on the driver side between 1 and 3 cylinder plug.

miss read your post you said sending unit i thought you said sensor

I said both, but yeah it's a switch. Thanks for the pics, I thought I had the wrong thing. Figured the switch would be for a light but evidently autozone got it right.

I have both of those . The nail head one is on the driver side between 1 and 3 cylinders. The flat head one is on passanger side rear of block
