Hi all.

I am well versed in pulling a 4.0 engine and or trans but have never pulled a 4.2- should it come out the top or bottom, and is there a tutorial anywhere I have not found by searching?

thanks in advance!

 

I've done it before on X308 top and and bottom, but always found bottom was easier for me, to each his own...


As for the X350 - I always did these through the top, taking trans out first from bottom, then removing hood and taking engine through top.


You'll need a 5 Point security torx bit to remove electrical connector for ECM. Disregard section about oil cooler unless you have the supercharged engine.

awesome- thank you!!

 

Let us know if it's that simple, any hickups or difficult parts. I may be doing the same thing shortly.

 

I plan on having this done soon. My mechanic says he thinks he needs a special tool to disconnect the engine from the transmission. Is that the case?

 

This removal is way out of my league but some pics of the process would be useful for identifying parts and locations.
Good luck!

 

Circling back after 4 years on this lol. I am back in the saddle with a 2004 XJR with a high LTFT, because I just had to have another.

I unbolted the AC compressor, which allowed me to remove the engine with no AC services. No special tools needed.

Separated the trans first, then unplugged everything and cherry picked the motor out. It was no more difficult then an earlier x308 or x100.

I recall removing the radiator though, which made things alot easier.
