Temperature Gauge
NOTE:
Temperature gauge sending units have single-blade connectors and are located on or near thermostat housings.
- If temperature gauge needle does not move, check for blown fuse or loose harness connector.
- To test temperature gauge, disconnect temperature gauge sending unit connector wire. Connect Red wire lead of Checker (49 0839 285) to sending unit connector and Black wire lead to ground.
- Use TEMPERATURE GAUGE RESISTANCE SPECIFICATIONS table to check gauge reading. Turn ignition switch to "ON" position and ensure needle position corresponds to resistance measurement. Fig 1 .
- Allow 2 minutes for needle to stabilize. Allowable limit of needle deflection is twice the width of the needle.
- If gauge readings are correct according to TEMPERATURE GAUGE RESISTANCE SPECIFICATIONS table, replace sending unit. If gauge readings are incorrect, check wiring. If wiring is okay, replace gauge.
