will this engine fit a 1999 jeep cherokee xj. does computer need anything done to it. will a new stock radiator be enough to cool the stroker.

Asked by: jeepseeker
Yes this will fit your 1999 XJ. Tthe computer will work fine with this engine as it is self learning. A new stock radiator should be sufficient to cool this engine. Additional Question can be directed to ATK Performance Engines @ 1-866-721-2315.
