There are a range of parts on your Mercedes-Benz that are related to keeping your engine's oil in good condition. The oil cooler is a component that is featured standard on some vehicles, but not all. If you happen to have one, it's important that you maintain it and get it checked out to ensure that it is in good condition. The engine oil cooler is something that works alongside your cooling system to remove extra heat from the oil. Heat from the oil is sent through the tubes of the cooler to surrounding coolant. Heat is absorbed by the engine's cooling system and then transferred to the air. The oil cooler is something built to last, but there are some signs that you might need to replace yours. If you see any oil leaking from the cooler, this is an indicator that you might have a crack or hole in the system. You also might find engine coolant leaking from the cooler. If you need a replacement Mercedes-Benz oil cooler, you're in the right place. We have several to choose from.
