CEThomas Posted February 11, 2010 Share Posted February 11, 2010 What 4.0 engine and trans came in the 99 ZJ? I am looking a one that needs a engine and trans replaced, and when I looked on car-part.com they give a different 4.0 (vin S) then in the 98 ZJ ???

Geonovast Posted February 11, 2010 Share Posted February 11, 2010 No such thing as a 99 ZJ Grand's: 93-98 ZJ 99-04 WJ 05+ WK Link to comment Share on other sites More sharing options...
Automan2164 Posted February 12, 2010 Share Posted February 12, 2010 IIRC, it is a 4.0L HO, and a 42RE... Or at least in my '98 ZJ it is... Couldn't imagine much changed other than the WJ body style in '99. Rob L. Link to comment Share on other sites More sharing options...
CEThomas Posted February 12, 2010 Author Share Posted February 12, 2010 Thanks Rob, The price difference between the 98 4.0 and the 99 4.0 for me is $881. Just trying to figure out why the difference. Link to comment Share on other sites More sharing options...
Eagle Posted February 12, 2010 Share Posted February 12, 2010 Did the 98 ZJ still have a distributor? I'm pretty sure the 99 WJ had individual coils on each spark plug. That might be the difference. Link to comment Share on other sites More sharing options...
dunl Posted February 12, 2010 Share Posted February 12, 2010 I'm pretty sure it was the 4.0 like the XJ until 2001. Link to comment Share on other sites More sharing options...
Geonovast Posted February 12, 2010 Share Posted February 12, 2010 I'm pretty sure it was the 4.0 like the XJ until 2001. Except the XJ received coil packs in 2000. Link to comment Share on other sites More sharing options...
shelbyluvv Posted February 12, 2010 Share Posted February 12, 2010 The WJ went to the coil pack in 1999 on the 4.0. The XJ followed in 2000. Link to comment Share on other sites More sharing options...

aemsee Posted February 12, 2010 Share Posted February 12, 2010 there are some other differences as well. the WJ water pump had an extra bolt holding it to the block. some other bolt placements are different. Threaded holes in the head for holding the coil rail. A/c mounting was high on pass side on ZJ, low on driver side for WJ........ Link to comment Share on other sites More sharing options...
