I noticed it after a shop installed a new clutch, which required the engine to be removed, coolant drained, etc., but nothing that should have affected how the gauge reads. Running on a cool day, temps were reading around 215-220 degrees. To ensure I wasn’t actually in danger of overheating, I checked various water-cooled locations with an infrared thermometer. Highest reading was right at the water neck/thermostat housing (191 deg F). The fuel gauge is reading accurately. I understand the under-dash instrument stabilizer can affect both instruments, but in this case, only one gauge is off. I plan to check the ground to the temp gauge and clean contact points at the engine sending unit and at the gauge.
