Where is Coolant Level Sensor (NOT TEMP SENSOR) located on ML430??
It is intermittently on and off.
Will a cleaning fix it????

Hello - take a look at the link below for the location and procedure.

Thank you for this info. On my vehicle ML430 I did locate it. It is at the back top of overflow tank and is hidden so not visible from front.

I also find that the sensor and tank come from MB as an integrated part only and costs $99. How silly of them to not sell as separate part. This is a trend I am noticing.

Any comments????
