2004 - 3.8 or 3.9?

Ok so I know that 2004 'Stangs were 3.8 until halfway through the year/production run, then were 3.9....question is, how would I know if mine is a 3.8l or a 3.9?

Run your VIN #. Or check your production numbers or w/e. There isn't any power difference, they just changed the Windstar engine in 04 so they figured they'd do the same for the Mustang. Minivan Engines!

look on the radiator fan shroud, it will say 3.8 or 3.9.
