- Disconnect temperature gauge sender wire and connect Gauge Tester (J-24538-A) between sender wire and ground. Turn ignition on. If gauge responds to tester accurately, replace sender. If gauge does not respond or is inaccurate, go to next step. If gauge responds well beyond "HOT", go to step 4).
- Disconnect temperature gauge lead at engine harness connector. Connect tester to lead that goes to gauge. If gauge responds to tester accurately, check wiring between sender connector and engine harness connector. If gauge does not respond, go to step 3).
- Remove gauge. Check for bad connections at gauge terminals or instrument cluster connector. If connections are good, replace gauge. If bad, repair connections and install gauge.
- Remove gauge and check for loose nuts at gauge terminals or lack of ground connection to gauge. If connections are good, replace gauge. If connections are bad, repair connections and install gauge.
