Question about 2003 Jeep Liberty

2003 Liberty Engine Swap Blown Motor How to fix timing.

Hi all, I have a 2003 Jeep Liberty, we took the 3.7l engine out and replaced with a 2004 3.7l ( out of a 04 liberty), everything installed great, we are left with one last problem. The new engine has a different reluctor wheel around the crank(more teeth), and our timing is off in coordination with the pcm on the 03 liberty. How can correct this timing problem, im sure someone has swapped a year or two newer motor before and solved this problem. Any help would be greatly appreciated, my baby has been sitting for over a month now. Just need to fix the timing and she will fire right up...Thanks Everyone for your help...Chad

Hey, did you ever figure this out? Ever consider swapping PCM's for a newer 04 PCM that would be tuned for this engine?

Will a 2003 3.7l Jeep motor swap with the same motor from a 2004? Jeep liberty


auto or stick shift??????
the EKG engine it is.
are you talking just a long block swap using all original
manifolds and all sensors.?

why not look it up.?
at jeep.com
or at Hollanders, call the wrecking yard, they use this service
they can tell tell you what fits. and not by year,
or they'd go broke fast.
the 3.7 is not only used on this one car, why limit self.?
my 2010 WK has it.


facts (to avoid issues) history of the block.
In 2005, the 3.7 engine was treated to numerous economy and idle-quality changes, with a new cam profile, lash adjusters, rings, and a 9.7:1 compression ratio.

seems 02 to 09 works for sure.
not withstanding cam and CR issues, fooling your ECU.

now jeep real, this the real p/n of said engine.
R2637056AB
you look it up online at jeeps. see what it fits.

I want to change a 3.7 motor off of 2004 jeep Liberty 2wd in order to fit my 2002 jeep liberty 4wd?


engine swaps are complex as is mixing engines to wrong transmissions.
so both are 3.7L, is that it?
you never said what exacty didnt fit.
the flex plate to TC
or TC to A/T pump side mismatch.
????????
if its the flex then get the correct flex plate.
or call jeep parts? ask them for the right parts
the side of the trans has the trans part number
my guess is all you need is the correct flex plate for engine to TC.

It could be a change in software from 2002 to 2003. You might try to get. Hold of a 2003 black box as the code will most likely be different.

My 2004 Jeep Liberty overheated for first time in 8 years. Took to shop and they ate uunning compression tests but not finding where the coolant and water leaked to. What could this be?


after overheating, you should immediately replace your head gasket. most of the time, your cylinder head must be shaved (the bottom part will be sanded to make sure there is a proper fit against the engine block.)

My mechanic Just replaced my blown 2002 3.7jeep liberty engine with a new 2003 3.7 jeep liberty crate moter. It won't turn over. He says no compression in any of the cylinders...(rocker arms too tight)...


Not much of an expert on this but heres a little pdf which should help a little if you wish to read up and do the work your self but it seems a little strange to have no compression. Please stay in touch and when i have more time i will do some fast learning about your specific engine. many thanks karl

2002 Jeep Liberty 3.7L Engine Swap to newer 2004 engine


Has anyone made this work yet? I have the same problem 2002 jeep 3.7 and just installed a 04 motor. Timing is off. Some one had a good idea of mounting the crank gear to the out side of the harmonic ballancer and mounting the sensor with a bracket. What about the cam gear on the left side. Does the timing cahain have to come off to remove it? Or has any one swaped the wiring harnest, and computer.
Please email me back. pcardoso@cogeco.ca Thanks for your help.
