Default 1991 L98 Mystery Sensor

All,

no clue what this sensor is. Found it under the car when I backed it out of the garage. It was under the radiator / condenser area.

There has been a small puddle of coolant that I’ve been waiting for warmer weather to figure out.

See pics. One wire sensor connector.




Im at a complete loss...maybe a low coolant sensor???

thanks

mike

Looks like a broken coolant level sensor to me.

Where is that located on the car?

Under the surge tank? Or up by the rad / overflow tank

The coolant level sensor is located in the bottom of the tank.
