Temperature Gauge
- Disconnect wiring connector from water temperature gauge from inside engine compartment. Install a test light between the terminal from connector and ground. Turn ignition on. Ensure that test light illuminates and gauge illuminates on the "H" (Hot) of LCD gauge.
- If results are correct, remove thermosensor (sending unit) from engine block and place sending unit in hot 158°F (70°C) water. Resistance readings should be 90-117.5 ohms at 158°F (70°C) on all models.
