Fits most ford, mercury and lincoln 4.0L engines and some 4.6L. Its been used off and on for a year and a half and still in perfect working condition. I used it, a Kinetic HC2000 and HC1400 with over 3kw and never went below 13.8-14.1volts. Its not the best alternator in the world but for the price its a good deal. They are around $500 new depending on the car.
Its for a 2002 Mercury Mountaineer 4.0L so if you have any questions about if it fits or not call EA at 344-712-9955 or ask me and I will call them.
