Some customers may comment that the low engine coolant level indicator is always illuminated.
The cause of this condition may be due to engine oil contaminating the coolant. Possible sources of oil contamination are internal engine leaks, improper service procedures, or the addition of some types of anti-leak additives to the cooling system. Once in the coolant, the oil leaves deposits on the level sensor creating an insulating film. This film results in a false activation of the coolant level indicator.
Diagnose low coolant level system operation and check the sensor for oil contamination using the procedure listed below.
