Generally, this is do-able as long as you are using all of the electronic systems that go along with the new motor/tranny swap. The donor vehicle needs to be the same or newer for emissions purposes as well as it must run as clean or cleaner than the target vehicle. (I see yours is so shouldn't be a worry). If your state has emissions testing, check with your DMV about the local rules on emission requirements when swapping drive trains. Lastly, you will want to make sure the chassis is the same between these years as if they are not, things may not be a simple bolt-in job. Good luck.,

    VIN won't help on that question. Check cars.com for the look on the model years. That's usually a good clue since the overall look will be basically the same during a model run. Another way is to join an enthusiasts blog for your vehicle and see if there are charts indicating the differences or just post the question there.

    answering for USA cars, and only 3.7L
    VIN K car. (engine = K = 3.7L)v6
    no engine stated or if 4wd?
    car-parts.com (wreckers net)
    this is the free, look up of all wrecked cars
    and they can tell you what engines swap
    no engine stated.
    how can anyone answer.

    "and computer" why say that,"
    all you need is a good engine
    a long block. none stated.
    2.4L engine or 3.7L V6
    ?>????????????????????????????
    are both 4wd????????????????????
    42RFE trans. in all. a/t
    the 3.7L is called by jeep the EKG engine
    if you pretend to by one, rebuilt.
    it tells you flat out what years match.
    why not do that on this unstated engine.
    a long block is devoid of manifolds
    and sensors matter too.
    they must be correct for the 2003. system.
    as you may not know, swaps are not simple.
    its a complex topic
    after all the PCM runs the whole car.
    drive line. and most match.
    this is no 1986 jeep.
    tell the helper what you dont want to replace
    is really bad form.
    you will do what must be done, no matter what. (Ill not tell you what smog laws are in all of N.America, ever)
    EKG started in 1999. (wiki that)
    its a chopped down 4.7L, v8 to V6
    they are sister engines.
    lots of 3.7L in jeep and dodges.
    in fact there are so many of them now
    many builder sellers need no core charge.
    im doing your job for you, im asking builers
    some say 03./04 are not same.

    2005 is major changes, new cam and valve and new compression ratio.
    my guess is they match.
    EKG for EKG blocks. (long)minus manifolds.

    the reman heads, with cam "D" shapped
    combustion chambers.
    match. 03./04, top sellers.
    all you need is EKG block long, less than 2005
    i think you have one.

    here are the ropes
    it must fit. (generational issues, abound)
    must run.
    must not confuse the PCM. or TCM !!!!(ask)
    it must pass smog, (if in a smog zone)
    or if in calif, it must pass inspection.
    they can fail you there on LOOKS alone
    wrong parts, or not listed in the EO book they have. (ask)
    I'd check engine serials too,
    who knows what is there, not me. not anyone.

02 jeep liberty backup !ights wont work bulbs are good


02 jeep. lib.
so fuse are first. anytime elect fail check fuses;.
stated over 1million time here, and is true.
then what is second, scan it, to see if PCM/TCM knows why.
The TCM (tranny brain will tell you if the TRS is bad, a fact)

all scan tool here in usa scan this car, and tells you why.
the car with a autotmatic trans (is it) has TRS switch
trans range switch.
this switch sends 12vdc to the rear when in REVERSE.
many of these cars have many engine choices, not stated here. nor what trans is there, the trans matches engines.
so.... each trans uses a different TRS,
to diagnose this we use a volt meter, if the TRS has 12v in
and no 12vdc out on the R pin , its bad.
easy no?
why not log into mitchell;s DIY and see the schematic there.
2002 KJ Jeep it is.
i have the book.
ill now guess, that its an usa car, and is automatic.
ok?
3.7liter engine
this trans the TRS is deep in side the trans, must drop trans pan to reach it, so we do all the above first, to avoid guessing and to do that we use a voltmeter to PROVE the TRS is bad
see?
if car is stick shift, is it? the switch is easy, on left side of box.
this is how all cars work , its called drive train if you post not telling that all you get is no anwser or wrong answers
is that good?, I think not.



this is the automatic, see part 5, and now deep that is?
this is pan off, valve body off view....
26309010-c5eqxh1jp52x53cr354rayll-2-0.jpg here is the schematic for 2002
that TRS is burried deep see?
if pin 1 is 12vdc in REVerse
and pin 6 is not, the TRS is TOASTED ! (BAD)

Hesitation is usually a dirty throttle body and idle air control motor.

Location of back up light switch for 2002 jeep liberty


The switch is on the outside of the transmission case. See a photo of it below. It may have a short lead on it or the harness plugs directly in.

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.

Power locks on 04 jeep liberty not working


Most of the times on jeeps and all chrysler auto's they have a body control modual this is what controls your door locks , windows ect. It should be in the owners manual for all fuse location and identification. A shop with a scanner can check the door lock system for you. body control moduals go bad alot on all chyslers and if you buy one you need to buy it from the dealership they will program it . So check the owners manual for a fuse and then have the body control mod checked
