Autometer guage not reading?

[babeabe19]

Hey i just replced my Lunar 2-1/16 watertemp guage (4137) and its still only reading under 150 degrees. I replced it cause the old one was doing the same thing and i thought it was a deffect. I wired everthing correctly as instructed. and i know my car gets over 150 degrees cause i drove all day in 90 degree weather. Please help me. Did wire something wrong

Where did you put the temp sender? Has it ever worked correctly? My best guess is that you T-ed it into the stock sender and got air bubbles next to the sender. I had to weld a bung into the aluminum thermostat housing and tap the sender into that in order to get it to work right.

How is yours installed?
