hello have a probelm hope someone can help?i have c320 2002 and coollant warning light coming on all time.it is also has the engine fan running all the time.i have changed the coolant level sensor but no difference.it is running at correct temp.does overheat etc.can any tell me where the fan relay is .thanks
Probly the sensor is messed up, i remember that when my C240 had the warning for the coolant, i just added more of the coolant and it went away. Also try to check everyday after the engine is on for a while if the temp of the car is the same, if it gets higher then you might have a problem and you can dicard that the sensor is the trouble maker.
