Temperature Gauge Test
CAUTION:
In Step 1), turn ignition off before gauge pointer reaches "H" mark. Failure to turn ignition off before pointer reaches "H" mark may damage gauge.
CAUTION:
Turn ignition off immediately after all gauge segments illuminate. Failure to turn ignition off immediately may damage gauge.
- Ensure ignition switch is in OFF position. Disconnect and ground Red wire on coolant temperature gauge sender. Turn ignition on. Ensure all light segments of gauge illuminate properly.
- If gauge light segments do not illuminate, check fuse No. 13 (10-amp). Check Red or Yellow wire for an open circuit. If fuse and wiring are okay, replace temperature gauge. If gauge is okay, test temperature gauge sending unit.
