COOLANT INDICATOR LIGHT/COOLANT SEN

Engine Cooling problem
1999 Mercedes Benz C230 4 cyl Two Wheel Drive Automatic 165000 miles

Coolant light on and off sporadically. NOT overheating. NOT losing coolant. Temp. Gauge on dash is reading 80 degrees C, normal. How do I replace the coolant sensor inside the coolant bottle a k a reservoir?

First you may want to call M/B and see if it is serviceable seperatly. Some are made into the resevoir and arent replaceable but as an entire piece. If replaceable, there will be a sliding retainer clip that holds the sensor in the resevoir, the new sensor should come with a new o'ring, if not be sure to get one while at M/B. Simply plug new sensor in the resevoir, slide retainer in and reconnect electrical
