engine from 02 to a 04

[groundedracer]

i have a 02 liberty with the 3.7L but the engine is blown and I cant seem to find one but I found a bunch for 2004 what would I have to do to use the 04 engine thanks

Same engine basically, just transfer your accessories, sensors, etc.

they changed the reluctor wheel (on the crank) at some point! you have to get the right motor with the right reluctor wheel. i believe it changed in 04? mike

Give you $500.00,come get it out of your way.

Won't it matter that he probably has a 45RFE transmission? Also what about programming the computer for that?

 

[HoosierJeeper]

I'd keep looking for one from a KJ with the 45RFE to be safe.

Or, swap in a CRD engine/******/programming...

Hmm

What do you plan on doing with the old engine?

Just sheer morbid curiosity

 

[groundedracer]

not sure what were doing with the old engine it is my cuzs jeep I am just doinig it for them at my shop I am guessing that I just need to swap the sensors from the 02 onto the new engine but want to check as the 04 engine is 550 and the cheapest 02 around me is 1800 with 135k on it


the old engine isnt bown yet just making some noise and it has 185k on it they want a new one in stead of fixing this one idk not my car

 

[ThunderbirdJunkie]

because the '02 engine is a one-year-only. the '04 3.7 won't bolt to a 45RFE transmission.

 

[Marlon_JB2]

what kind of noise? inquiring minds want to know.

Why not remove / rebuild and reinstall the esisting engine in the KJ? You'll get a motor with 0 miles on it again and probably end up with a small warranty in the process..?

You'll have to find a 2002 block or reuse yours as far as I know.

Why won't an '04 3.7 bolt up to a 45RFE? Did Jeep change the bolt pattern the bell housing bolts up to when they went from the 45RFE to the 42RLE?

 

[ThunderbirdJunkie]

It's not the bellhousing bolt pattern, it's the spline count ITBJRC

 

[ShafferNY]

Okay. I'm drawing a blank. Spline count on what?

Flywheel bolts to the crank, torque converter bolts to the flywheel, transmission engages with the torque converter.

Am I missing something. kopkrab.gif

I'm scratching my head on that one also.. Especially the "ITBJRC" What???

 

[kb0nly]

Also considering the 03' model year came with either of the trans i'm sure they didn't change the bolt pattern of the bell housing or on the block, they should be interchangeable in that sense.

ITBJRC- If Thunder Bird Junkie Remembers Correctly...
