Wj Generation Introduction:

The WJ Grand Cherokee replaced the ZJ generation. The 1989 model year designation in the product name is a common discrepancy in aftermarket manuals; the WJ generation actually debuted for the 1999 model year. This manual likely covers the 1999-2004 WJ Grand Cherokee, but specifically references the 2.5L diesel, which was common in European markets and less so in North America for the WJ. Assuming the product name intended the 1999-2004 WJ platform with a 2.5L Diesel option.

Manufacturing Plant:

Jefferson North Assembly, Detroit, Michigan (for North American models)

Production Years Wj:

1999-2004
