Lightbulb Coolant level sensor

Please help. How to replace coolant level sensor on 2003 C320 4Matic?
It's already about a month as I read: "Coolant. Check level"/Washer Fluid. Check level".
All fuids are OK but sign is still coming every time I start engine.
Thanks for assistance.

Who the hell decided that low coolant / low washer fluid would both share the same warning message? One is a LOT less critical than the other!!

The coolant level sensor should be under the coolant expansion tank. It has wires connected to it. Just pull it out and disconnect/replace if it is faulty.
