It’s important to use 9.5 liters of coolant which has Green color. Otherwise 200 Series made in 1988 won’t serve you long enough. In 1993 the company produced vehicles with 2.5 engine having code of OM602.912. Only exact type of antifreeze will suit Mercedes-Benz 200 Series cooling system. Don’t underestimate the importance of Mercedes-Benz’s 2.6 engine cooling system.
So, don’t choose different from Red coolant and obey the number of 9.5 liters. There is a big plus in servicing 1993 Mercedes-Benz 200 Series with all regulations. Providing you keep the rules 2.5 motor installed in 200 Series of 1990 year will be long lasting. Every Mercedes-Benz owner should remember that engines with code M103.941 are quite demanding.
