Hi all,
Just completed the conversion to an electric fan setup on my '71 M code. As part of the installation I now have a digital temperature readout from the fan controller and noticed the temp gauge in the car seems to read high, or at least higher than my previous '68-'69 Mustangs. For instance, when the gauge in the car reads half way, the digital temp readout is 172F. When the gauge reads 2/3, digital readout is 180F and when the gauge is almost full scale, the digital readout is 194F.
The thermostat is a 180F unit so I would expect the car's normal operating range to be something like 180F-190F. As a result the gauge reads around 2/3 scale most of the time which is not what I'm used to. Is this typical for a '71 or is my gauge reading too high due to either a gauge or sender malfunction?
