The six cylinder is a 4.0L, The V8 is either a 5.2L or 5.9L
Look at your VIN number. Assuming that the engine in your Jeep is the original one the eighth digit of your vin will designate the engine size that your jeep came with. The codes are as follows: S = 4.0L inline six, Y = 5.2L V8, Z = 5.9L V8, N = 4.7L V-8, J = 4.7L High Output. This spread of engines covers model years 1993 through 2004 with 1995 pretty much having the 4.0L, the 5.2L, or the 5.9L with the 5.2L (318 cu in) being the most popular.
