the head of the oil pan drain plug is rounded off and shows signs of a thread sealer being used before
My car has 117510 miles.
My car has an automatic transmission.
To remove the drain plug, turn the plug counter-clockwise. You may need to use a "bolt-out" type socket to grip what remains of the head. In the event that the internal (in pan) threads are damaged and you need a helicoil inserted just request an oil/filter change and the responding certified mechanic will restore the threads during that operation. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
