4.0 Inline 6 block, interchangeable with???????

Are all 4.0 Inline 6 blocks interchangeable? Meaning can you take a 89 Cherokee block and throw it into say a 2001 Grand Cherokee? or other way around?
A block is a block right?, same mounting bracket placement, bolt pattern for tranny, intake/exhaust ports, sensor placement and such?

Not necessarily. I ran into this when I bought a 2001 WJ with a known-bad motor. There is a difference in the 2000+ blocks for the WJ/TJ that relates to the motor mounts, accessory mounting locations, etc. I thought I was in good shape because I have a running 1995 4.0L in a rusted out XJ. Nothing could have been further from the truth.

The 00+ WJ/TJ block will have the alternator mounted high on the passenger side, where the AC compressor is mounted in the XJ, and the AC compressor is moved to the driver's side of the engine. This engine also uses coil packs and a distributor-less ignition, requiring mounting bosses for the coil packs on the head.

Any 1990-2001 XJ Cherokee or 1993-98 ZJ Grand Cherokee 4.0 L engine block will interchange.

Remove and re-use as needed or required from your original engine: Intake/Exhaust manifolds, flex plate/flywheel, cylinder head, distributor-less ignition or distributor assembly, engine sensors, fan belt driven accessories and mounting brackets.



XJ/ZJ blocks and 2000+ TJ/WJ blocks do not interchange.

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

What, exactly, are you wanting to do?

If you own a Renix Jeep, you'll want to check this out.

@ cruiser54, Ive been looking for a decent used motor to slap in a 96 Cherokee Country w/4.0! I have a 4.0 already with 300,000+ miles but really wanted something with less miles. All I really want is a motor swap, thought all 4.0 were the same, glad I asked or could have been out another few hundred bucks!

I agree with Cruiser 91 to 99 that way you do not have to deal with a 00 or 01 head swap to bolt the down pipe to the exh. manifold.
