If this is a mechanical gauge check for a "kink" or pinch in the line.Had the same problem and found a pinch.There is fluid in the pipe which expands as it heats up.Be sure the "excess" pipe isn't wound up too tight.

No, you would be reading the water as it came from the radiator, would be the coolest spot in the system.

Are you using the stock sending unit or one that matches the aftermarket one?

Sounds like you have a mechanical gauge(no electric hookup?).You might want to drill and tap a hole in the intake back from the stat housing.Thats where I have mine located.

My thought is that the gauge is defective, not the location of the bulb. Take the gauge out and take it in the house. Put the bulb in a pan of water on the stove, and heat it up. If you have a cooking thermometer, put it in the pan and compare the readings, all the way to boiling. If no thermometer, boil the water and see if the gauge reads 212 degrees.

Do you have a thermostat in the engine?
