What tool is needed to remove the oil drain plug on a 1988 Pontiac fiero?
A 1988 Pontiac Fiero typically uses a 13/16 inch (or 21mm) socket to remove the oil drain plug. However, it's always a good idea to double-check your owner's manual or consult a repair manual specific to your Fiero's engine (2.0L or 2.8L) to be absolutely certain. The size *could* vary slightly depending on any modifications.
