2.Drain old oil:Find the oil drain bolt in the oil pan and slowly drain out the waste oil in conjunction with the oil receiving basin. This process takes about 10-15 minutes.
3.Remove the old oil pan:Use a special wrench to turn it counterclockwise. Note that residual oil may leak out. It is recommended to wrap it in a plastic bag during operation.
