Genuine Mercedes Oil Pan; Lower | 6420102228
Make Sure It Fits
Oil pans are the lower cover of an engine or transmission and are the reservoir to hold engine oil or transmission fluid until needed by the engine or transmission. They are often stamped metal that bolt directly to the bottom of the engine block or transmission valve body case and have a threaded drain port with a drain plug to drain oil or transmission fluid for routine maintenance.
Oil pans are not often replaced unless damaged. Road debris hitting the engine oil pan can dent the oil pan preventing oil or transmission fluid from being picked up by the oil pump. The impact from road debris can also cause the oil pan not to sit flush against the engine block or transmission valve body case, creating leaks. Stripped drain ports can also cause leaking from the oil pan. Transmission oil pans containing filters will require regular replacement of the filter.
Oil pans are sealed to the engine and transmission with gaskets, usually made of cork or silicone, with some engine oil pans only being sealed with liquid silicone that hardens to create the seal. Engine vibrations and deterioration of the gaskets and sealant can cause the oil pans to leak where they are mounted and will require the removal of the oil pan to replace the gaskets or sealant.Replacing Your Mercedes Oil Pan
When replacing or resealing an oil pan in your Mercedes, it is essential to thoroughly clean the mating surfaces of the oil pan to the engine or transmission and use the vehicle manufacturer's torque specifications. Even the smallest amount of dirt or debris can cause the oil pan gaskets not to seal properly, causing the pan to leak. Likewise, over-tightened or under-tightened oil pans can cause the gaskets or sealant to not hold in place, creating oil leaks.
