I am thinking about doing DIY maintenance on myMercedes Benz 190D cooling system this time to save on labor cost. What exactly are the things that I need to check to keep my car's cooling system smooth and running?
Checking your Mercedes Benz 190D's cooling system is quite easy. You should keep in mind that a 50/50 mix of coolant and distilled water can help keep your car's cooling system in its proper shape and prevent deposits and corrosion from building up inside. Double check your coolant level only when your car is on a level surface and the engine has cooled down. This will allow you to have a more accurate and hassle-free reading of your car's coolant level. To determine the coolant temperature in a Mercedes Benz, simply turn the SmartKey position to 2 in the ignition lock and check the coolant temperature displayed on the instrument cluster. If you need to add more coolant, be sure to open the coolant reservoir only when its temperature is below 158 degrees. Rotate the cap one-half turn slowly counterclockwise to get started.
