1996 Mercedes-Benz S500 Question: How to diagnose sudden coolant leak/major leak ?
A vehicles cooling system is of essence to the motor. Its best not to take these type of problems lightly. Have a knowledgable shop pressure test the cooling system for leaks. A coolant leak is relatively easy to find. - msportdiv
This could be a major issue you should check to se if there is a milky looking fluid ( oil and water do mix in high heat and pressure turns to a milky sludge ) SO check your oil for this and also check your coolant by removing radiator cap look for the milky sludge if you see it in either one of these places you have a blow head gasket sorry also the antifreeze will burn off and give you whitish colored smoke NOT GOOD!!!!!! - mrshadey
