Q: oil drain plug

asked by on

How do you remove a rounded drain plug where you can't put a wrench on to remove the bolt. I have tryed vise grips and pipe wench, but still does not move. I spryed penatrating oil and let it set for 2 days and nothing. What can a home mechanic do? I have limited space to remove the oil drain plug. thanks Paul

You would use a bolt-out spiral fluted socket. A common example of this tool is the Craftsman 10 pc. Damaged Bolt/Nut Remover Set Low Profile Bolt-Out (Item # 00952166000P Model # 52166). However, Irwin makes a set as well and you can see it in Home Depot. Upon removal, inspect the threads in the oil pan for damage. If the threads are damaged, seek a professional repair.
