Hello, i see threads on this but Will a 4.0 from from a 2005 XJ (grand cherokee) *edited* fit a 91 Laredo?

and are the engine mount bosses in the same place?

i dont understand if the comptability will be the same between these two engine blocks.

gota buddy giving me a free engine.


appreciate the help!

 

There is no 2005 xj...possibly a Grand cherokee...

 

I stand corrected.

 

The Grand Cherokee is not an XJ. Since your asking about a 2005 4.0l motor I'm going to assume your not in the US as the 2005 US model Grand Cherokee never had the 4.0l as an option but outside the US it did.. the Euro 2005 Grand Cherokee is coded WG, the US version is WJ.


Simple answer, No. The blocks are missing mount points used by the XJ.

For reference:

XJ Cherokee and ZJ Grand Cherokee 4.0L engine blocks interchange.

2000+ TJ Wrangler and WJ Grand Cherokee 4.0L engine blocks interchange.

XJ/ZJ blocks, and the 2000+ TJ/WJ blocks DO NOT interchange without significant modifications. (1991 to 1995 YJ and 1997-1999 4.0L TJ Wrangler blocks will interchange in XJ/ZJ and visa-versa).

TJ/WJ 4.0L Engine blocks underwent clean sheet design changes effective in the 1999 WJ Grand and 2000 TJ Wrangler. These blocks are not interchangeable with XJ/ZJ engine blocks. The reason is motor mount bolt holes and belt driven accessory mounting bolt holes are in different locations, or not present at all, TJ/WJ vs. XJ/ZJ.
