My coolant gauge in my 71 cuda 440 reads about 3/4 or more when fully warmed up....Shouldn't it read towards the bottom just pass the first line, I have replace the gauge twice, I have replaced the sender twice, and I have replaced the limiter, my challenger reads about the first line..and before you ask I have checked with a temp led gauge reading about 181 degress at the water pump... Both are the same temp, 181 for their respective gauge readings? Kevin

Could be poor contact at bulkhead connector or gauge out of calibration. Another source of resistance is where the wire connects to the circuit board Jim

Thanks guys, all the wiring is new( yes I know that dont mean squat) I agree with Andrew on the resistance, I noticed 68 uses a different sender, does and one know the difference in resistance , are and which way to go on a resister. hard to believe everything is out of whack, just bothers me to see the gauge that high, but knowing its not running hot,and nothing is working..

There is a 15% +/- of tolerance for the resistance output of a sensor. Also for the posted discrepancies, what brand was the sensor? Aftermarket sensors can/will vary alot, that's why we always try to use an OE sensor. Just my $0.02...
