Temperature Gauge

The temperature gauge on the control panel indicates

temperature sender signals the temperature gauge.
The temperature gauge should display the first green
segment when the ignition switch is turned to ON. The
first yellow segment on the gauge should display when
engine coolant temperature is approximately 212

When engine coolant temperature rises to approximate-
o o
ly 221 F (105 C), the temperature gauge should display
the first red segment.
