Coolant Level Indicator Lamp: Description and Operation
General
The coolant level sensor (S41) is not directly enveloped in coolant and can be removed and installed without draining the coolant in the expansion
reservoir (1).
Function
If the coolant level is too low the ring magnet (54) in the float (1) closes the contact (arrow) in the coolant level sensor (S41).
The permanent input signal (vehicle ground) exists at the base plate (a) of the instrument panel unit (A1) and the indicator lamp (A1e11) lights up
brightly.
