76 Duster Overheating at idle
The question about the temperature is twofold.
1. Is how hot ?
2. Did it rise suddenly? Parked after driving doesn't count. It always rises quickly when parked and shut off.
This from page 10 of the 1975 Plymouth Valiant Owners Manual.
'76 wiring is different than '75 but the gages information is pretty much the same.
The gage should be labeled the same as the one shown here.
Center is around 185 * F
That's below the opening point of most late model t-stats.
I'd expect the needle to be a bit to the right of center on a fully warmed up engine with a 190* t-stat.
After restarting after a short drive, the temperature should drop but will do that better at idle with a fan shroud.
