OE#A0029902017 Oil Pan Drain Screw For Mercedes C63 For AMG Fitment Parts

The working principle of the oil pan drain screw is to control the opening of the oil pan to achieve the discharge and replenishment of engine oil.
The oil pan drain screw is a screw installed at the bottom of the oil pan. Its working principle is based on gravity and pressure difference. When it is necessary to drain the engine oil, unscrew the oil drain screw, and the engine oil in the oil pan will flow out due to the force of gravity. The design of the oil drain screw usually includes a sealed gasket to ensure that the engine oil in the oil pan does not leak when the screw is tightened. In addition, the threaded design of the oil drain screw can prevent the screw from accidentally loosening and causing oil leakage when draining the engine oil.
