ENGINE Temperature Indicator
- On models with ENGINE indicator, oil pressure and temperature switches control light operation. Indicator should come on with ignition on.
- If not, check bulb. After checking bulb, disconnect lead from oil pressure switch and connect lead to ground. If light comes on, replace oil pressure switch. If light stays off, check circuit from oil pressure switch to indicator bulb.
- If light remains on with engine running and coolant temperature is less than 249°F (121°C), disconnect leads from both switches. Light should go off. Connect oil pressure lead. If light comes on, replace switch. Connect temperature lead. If light stays on, check for short circuit from either switch to indicator light bulb.
