Tahoe 4WD V8-393 6.5L DSL Turbo VIN S (1995)
Temperature Gauge: Testing and Inspection
Gauge Indicates Hot When Engine Is Cold
This condition is generally caused by a shorted or grounded circuit.
1. Remove sensor lead at sensor unit. Gauge should move to COLD position, if not check unit for a external short. If no external short is found,
replace sensor.
2. If gauge stays HOT, check for a short circuit in gauge to sensor wiring. If circuit is satisfactory, replace cluster.
