cooolant level light

[doskow@domain.elided (MEL ODIOUS)]

Hi!
     Those coolant level sensors on 164s, like other sensors make
     contact to complete the electrical circuit when conditions are
     OK.  Good in theory, the light on means that the sensor is finding
     a low condition, or that there's a bad connection in the circuit.
     Whilst cleaning goo out of my reservoir (now i'm convinced of no
     ongoing head gasket oil > coolant leak) i did ignore the extruded
     warning & unscrewed the level sensor.  it & its well were rather
     gloppy, after cleaning it all up i get no more fraudulent low
     coolant warning light.
