If you disconnect the sender wire and hook up a multimeter ohms 300
+to sender -to ground, the meter should show less ohms as the engine
warms. If you know what the ohms value for 75degree and again for
150DegF you could compare it to your test and prove the sender. The
temp gauge is nothing more than an ohm meter.

I find it best to price the OEM sender and the gauge first. often
you can find a more modern new pair(sender, gauge) for less than the
cost to replace one or the other of the classic,OEM hard to find
parts.

the ohm value for the sender at a given degree has to match the gauge,
they are a pair. one thing to look at is the scale . you dont need a
gauge over 250 degrees and under 130 ( the wanderlodge 94,8v92
watertemp gauge is the worst example of a useful scale)..

Some time the wire between the sender and gauge is screwed. if it is
close, jump a wire and look to see if a hot engine moves the gauge
any?

dont use tefflon on a new sender.

an idiot light is prompted by a switch not a sender, they look alike
