Cannot remove 4.0 ltr engine block drain plug. What is the next best alternative?
I'm doing a radiator fluid flush on a 2002 TJ and have been successful right up until the engine block drain plug. Have made the correct fitting to go into the plugs square hole but the plug is not going to come out (square hole has now been gnarled into a more circular hole) regardless of force and lubrication.
Is there another point on the engine block I can drain as a second best option instead?
