C 43 AMG (202.033) V8-4.3L (113.944) (1998)
Temperature Gauge: Testing and Inspection
Test Coolant Gage
Remove, Install
1
Remove coolant level sensor (S41)
NOTE: The coolant level sensor (S41) is not enveloped directly with coolant and can be removed from the expansion reservoir or radiator
without draining the coolant.
2
Connect multimeter (DMM-5) to coolant level sensor (S41)
Inspect
NOTE: Use float with ring magnet from expansion reservoir of models 129, 140, 202, 208, 209, 210.
3
Test switch point of "maximum" coolant level
NOTE:
-
Test without using ring magnet!
-
If the resistance indicated by the multimeter (DMM-5) is equal to infinite, Install new coolant level sensor (S41).
4
Test switch point of "minimum" coolant level
NOTE:
-
To do this guide ring magnet (1) along coolant level sensor (S41) until the contact in the coolant level sensor (S41) switches.
-
Specified resistance = 5 Ohms
-
If the contact is not switched or if the resistance indicated is too high, Install new coolant level sensor (S41)
5
Install in the reverse order.
