Oil Sump Nut or Oil Drain Plug is located on either the bottom or side of its oil pan. The plug keeps the motor’s lubricant from pouring out because of the constant effects of pressure created inside of the vehicle’s crankcase and gravity itself.
In the 1980s and 90s, cars typically had steel oil pans. Now, vehicle manufacturers have moved towards aluminum oil drain pans for better heat transfer purposes.
Due to the softer aluminum characteristics compared to steel, cross-threading and overtightening can easily strip the oil pan.
