Coolant Temperature Gauge Does Not Operate
Remove the instrument cluster. Check the temperature gauge by changing the resistance between the terminals. Apply battery voltage to the terminal 1f, ground the terminal 1b, and connect the resistance to the terminal 2c and then check that the pointer is moved as shown in table.
TEMPERATURE GAUGE RESISTANCE TEST
| Temperature °F (°C) | Resistance | Angle (°) |
|---|---|---|
| 122 (50) | 180.5 | -30 |
| 185 (85) - 221 (105) | 48.7 - 26.5 | -5 - 5 |
| Over 250 (125) | 15.9 | 30 |
