Engine replacement checklist KJ 2002 2003 and maybe 2004
Also, mine wasn’t a reman. Although I wish I would have went that way now. The only motor that will will work in a 2002 is another 2002. Possibly 03 depending on man date. In short I had to split both motors and swap the crank shaft reluctors and camshaft sprockets to make rhe 04 work with an...- KidsKJ02

Engine replacement checklist KJ 2002 2003 and maybe 2004
Great write up! I’m just wrapping up a similar transplant now as well. I swapped in an 04 into a 2002 job 1, which meant a lot of other issues not covered in other write ups. For example the job 1 Libby had a different transmission, so I had to change out the flex plate and starter as well...- KidsKJ02

Engine Swap Overview
No, I didn’t swap them out as they had the same part number and plug pins. I suppose I could try there pretty easy to get to however, I believe I found my latest issue, after coming to terms with the thought of breaking it down again, I went to remove the right side cam shaft sprocket and... -
Engine Swap Overview
Hello! Wondering if you or anyone else is still monitoring this thread as it was a great write up! I in fact used it to do my engine swap as well however, I have no happy ending yet. I dropped an 04 3.7 into my 02 KJ AFTER changing out all the internal timing parts mentioned above, so I... -
04 to 02 Engine swap
Darn, I wish I would have checked this reply months ago... I couldn't find a new short or long block anywhere for under $2500. I just completed all the internal parts swap and dropped the motor back in bolted it up, only to find the 04 flex plate will not align with the 2002 torque converter...- KidsKJ02

04 to 02 Engine swap
Yeah, I looked at jasper and a few others, that’s what I wish I could have done too however, I just can’t justify dropping a $3200 short block into a $700 car. I just pulled the reluctor out of the blown motor today Confirming there’s no way to get that out without removing the entire crank...- KidsKJ02

04 to 02 Engine swap
Also I’m thinking I may have posted this on the completey wrong place/page as its nothing but crickets my apologies. I thought I saw some heavy engine work posts on here in the past. If anyone on here has ever swapped a newer 3.7 into an older chassis please dm me or email me. I’ve rebuilt...- KidsKJ02

04 to 02 Engine swap
PCM swap isn’t going to work. 02 has 3 plugs 04 has 4. Darn looks like I’m splitting another engine open.- KidsKJ02

04 to 02 Engine swap
Ok thanks. Yes it’s the 3.7 V6. Not sure on the gearbox? will have to research that a bit more. There are several forums on the net covering this as it seems pretty common as the 2002 3.7 is pretty hard to find these days however, every one of those goes into depth on changing out the timing...- KidsKJ02

04 to 02 Engine swap
I have an 02 limited in decent shape with a blown motor and rusted out 04 with a good motor, I’ve already pulled both motors and broke down the blown one. I was hoping this was a straight forward plug and play option but after much research I’m seeing I will have to change out the crankshaft...- KidsKJ02
