The sensor is screwed into the oil pan and lights a warning signal on the dashboard when engine oil is low. As a check to make sure the bulb is not burned out, the light comes on every time the ignition is turned ON and goes off as soon as the engine starts.
REMOVAL & INSTALLATION
See Figure 1
Do not confuse the oil level sensor with the oil thermal unit (mounted below it) on some models.
- Drain the engine oil.
- Disconnect the sensor wiring.
- Remove the attaching nut or bolts and remove the sensor.
- Check the oil holes in the sensor and clean with solvent if clogged.
- Fit the gasket onto the sensor, then install the sensor with the L mark (1979-80 only) on its body pointing downward.
- Tighten the nut to 18-22 ft. lbs. (24-30 Nm) and connect the wiring.
- Fill the crankcase with oil to the proper level, then check the sensor for oil leaks with the engine running.
