    I think not. Technology has found replacements for oil, it's just more expensive.
    Remember, the first diesel ran on peanut oil not dino oil.

    I traded a 2002 Jeep Renegae to this jeep the dealer paid over 18,000 for this jeep this jeep was a good one I wish I had kept it it only had 15000 miles that is why I stayed with another Jeep the new one was 29,650. The more you own the harder it is to get them to trade. I would trade this one in a heart-beat if I could. Someone wrote in about fueling and a exploxsion leaving jeep run that is a good idea. :lemon:

    My torque converters and others..
    How many trannies have fallen?
    Did you also eat an egr? Still have heat issues?

    I just recently experienced the rapid heat runaway. These two times weren't even on the hottest days here in North Texaxs So it's not like our crd was made with a bad fan to start. Is this a precursor for the egr or tranny?

    I have no idea where an add'l cooler could be mounted. Cooling is a very complicated engineering problem for gassers let alone a diesel. Quick warm-up for emissions, desert heat and artic cold. Not an easy engineering assignment.
    Perhaps a complete redesign by an old engineer brought out of retirement is needed or five more dollars of parts cost per vehicle by dc and then us.

    2002 Renegade

    Before finding the CRD on a showroom floor, we considered a Renegade while looking at Jeeps for my wife's uncle who had owned Jeeps in the past.

    Size and price and top ten worst list for 2004 kept us away.

    It seemed the renegade would've been the choice because of the 3.55 gears. Skid plates. Jeep hood. We never drove one.

    Last repair trip to the dealer, rental company provided a new sport(4.5K miles on odometer) auto 3.7 4x4 3.73 gears. My impression was hot out of the pocket but no highway passing performance, and ate gas.

    Lurking lost, is it really true that renegade (or sport w/2B) which have the 3.55 gears, also have a front differential that is not aluminum?

    What is your take on the Edmund's Liberty Problems posts?
    I've read the - can't go backwards up the drive at two locations here.
  • tired_old_davetired_old_dave Member Posts: 710
    Good for you. And I sincerely hope that you get 500k miles and twenty years of use from your Jeep CRD. Surely that is why we all bought them.

    I really never want you to experience any of the problems some of us are experiencing. The fall from exuberance to kick in the face reality is something I wish no CRD owner should ever have to face.

    I thought that DC/Jeep would've spent some good time and money in design, parts purchase, and a slower asembly line to not produce a marketing misfire like GM on trying to introduce a diesel.

    Some of us over the years have asked for a full sized half ton truck with a good little diesel. We've been waitng for a diesel without going 2500/3500.

    I think they are waiting for universal clean diesel - then watch Hyundai or someone satisfy the desires (with quality).

    I'm not here to destroy resale of the CRD or cry the sky is falling. I am learning here and enjoying some posters like caribou1. I still have the box of Sam's plastic gloves under the drivers seat. Do you remember that?

    Anyone know if the CRD will qualify for the diesel and hybrid tax break in the new energy bill? Up to $3400 tax incentive starting in '06.

    My CRD Limited came with the Sirius radio installed. The antenna is located on the right front fender near the window. I haven't checked the connection, yet, but I'll try to see how they ran the wire.

    My EGR valve was replaced at 6000 miles and the computer "flashed".I finally decided the rapid temp changes were bogus and ignored them.Now the TSB for the temp guage is available so I'll have to get scheduled for that.I have read in this forum and in another [JeepForum.com] of several transmission failures most likely caused by high operating temperatures.As few of us as there are it would seem to be a rather high failure rate in a transmission touted as strong enough for a Hemi.
  • datamandataman Member Posts: 12
    Has anyone with the overheating issue had the new TSB applied? If so, what are the results?
  • caribou1caribou1 Member Posts: 1,354
    Well, there was a british article saying that in the early 19th century 80% of the agriculture in the UK was for feeding horses, and 20% for the population. Here in France a recent study mentionned something like less than 10% of the fuel could be produced from agriculture. We are still far away from the needs and not accounting for development of the rest of the world where most of the population lives. A compressed air engine was developped in Geneva for a subminiature car, hydrogen cell technology is just showing the tip of it's nose. At least these two systems could be recharged with electricity. I don't yet understand why hybrid vehicles could not be recharged using standard ac outlets like block heaters. Their only source of current comes from fuel :confuse:

    The day is coming when you will be able to plug her in.
    soon...
    It just too bad that we weren't so dependant on commodities...
    But I believe we will never be rid of the oil barons' wrath.
    The day that Hybreds are the in thing
    ,Don't you think the oil companies will want to take over the power corps as well?
    ,so they stay in buisiness?? ,
    And since they'll know we will need power for tranportation ,that demand will drive up the price as well.

    Well it's happening now in Canada and the U.S..
    We just deregulated our power stations ,and whammo !....paying 11 cents/Kw hour ..How and why is the price raised ??.
    Just like fuel...
    Demand drives price, don't you agree??
    :surprise:

    I personally find the front grille of the Liberty to be puny, unstylish, and unimaginative, relative to the rest of the vehicle. Before I knew much of anything of overheating problems, I thought about the possibility of fabricating a grill adapter that might allow greater air induction and an easily removable "bug screen" to help keep the little nasties out of my precious cooling infrastructure. Seems to me that one or two extra tranny radiators could be fashioned at either side of such an adapter, which could easily port away to the side(s) from other cooling devices. Any thoughts?

    I went to another dealer one that I had deled with before, a small town dealer that I have always had good luck and somewhat trust if there is such a thing. ask him about my diesel and the jerking try to explain to him he said the TSB-018 update didn't have anything to do with my problem this Jeep only acts up once then runs good. He told me to just wait and see if DC came up with something they have these BIG HORN Trucks up there I think I am the one that got the BIG HORN. Sorry about slow response I work 3 shift. I work on USA heilacoper they don't stop like my jeep they are tested tested and tested........... I wish my Jeep was tested or at least drove. :cry:

    Mine came as factory installed Sirius. the antenna is located on the roof on the back right in front of the roof taillight.

    I am considering purchasing a Jeep Liberty Diesel after test driving one last week. I was wondering if I could hear from some current owners who have had experience in cold/winter how it starts (and runs) in very cold weather. Some of our winter nights in Ontario, Canada can get as low as -20degrees Celcius (-5 Fahrenheit) to -35degrees Celcius (-20 Fahrenheit).

    I read one review that indicated it was very noisy in cold weather starting (much more so than starting it in warm weather) for quite some time and power (as well as gas mileage) was very sluggish until it completely warmed up. Would this be accurate?

    I usually plug in the block heater on my gas powered Jeep on most very cold winter nights and have not had any problems with winter running.
  • dfw2dfw2 Member Posts: 11
    The CRD was introduced in late winter so you probably won't find many owners with cold starting experience, yet.

    I bought mine in early March, live in the Mountains at 7,300 foot elevation, and experienced some cold starting conditions, but not the severe conditions of December/January/February. In the first month I owned it, morning temps were usually 20 F or lower, and as low as 5 F.

    At those temperatures, I did not experience starting difficulty. When the diesel started, it ran a little more rough and smoked a lot more than when starting at warmer temperatures. Power output was reduced noticeably but only for a short period of time, and not to the point that I consider unacceptable. The review you quoted stating that full power could not be obtained until the engine is completely warmed up is false. Acceleration when first started is jerky and slow but after the first acceleration, is acceptable.

    Another observation is the rate the diesel warms up and able to deliver heat to the cabin is much faster than gas engines. We really appreciate the fast warmup!

    As we enter fall, and approach the coldest months and uncharted cold starting territory, based on my experience I am not concerned about cold starting and operation. The only concern is the condition of the fuel at extreme temperature such as minus 20 to 30 F. Will the diesel fuel be seasonally formulated adequately to flow?
  • mdamickmdamick Member Posts: 277
    The coldest it has gotten here so far is the mid 30's F.
    It will clatter and smoke a little like a real diesel for a couple of minutes & then smoothes out.
    I have found on the Cummins that if you plug it in it starts just like warm weather, I would expect the CRD to do the same.
  • vtdogvtdog Member Posts: 163
    I live in NH and bought the crd in early march. I had a number of days in the low 20s. Starting was not a problem (2 sec glow plug wait). I don't know how it is going to be when it gets to 20 below (F), but i'm hoping for the best and suspect it will be ok with the "new" glow plug technology
  • caribou1caribou1 Member Posts: 1,354
    We pay electricity around 15 cents of an Euro per KWH (1.8x to the CAD, 1.25 to the USD).
    Oil companies here are asked to modify their sulfur extraction process to meet the new specs, and some claim they can't invest before 10 to 15 years. The local government is announcing they will sell shares of toll roads that bring ~30 billion profit per year and they want to invest in a huge railway tunnel to Italy. This smells like a warning for fuel shortage and an announcement for profit from public transportation.
    Do I have to get new tires for my bicycle?
    Domestic heating oil for our house was 540 Euros last year, 850 this spring and 1200 right now. Do you have the same situation where you are?
    Sometimes I fell the CRD will be the last one of it's kind.
  • sailormonsailormon Member Posts: 48
    Ok, take a moment and edicate me. What is this about a TSB. I know it has something to do with temp and perhaps the built in comp??? Or will this device or whatever be part of the new 06? I can relate to boat building or perhaps cell structure, but mechanics are another thing. BR
  • sailormonsailormon Member Posts: 48
    I have been on the net looking for an out due to rising fuel prices. I have always considered myself ahead of trends. But know that in europe, small scooters have been part of transportion for some time. America is now having an upsurge of sales as well. The jest is, when I go south to Fl. this fall, I will be buying one and parking my liberty except for occasional use. Using it to haul a boat north and south will be it's role while using my bike and scooter will allow many years before I wear the liberty out. In fact I am considering selling my other car up here as well and just load the scooter on the trailer and take back and forth. Great gas mileage!
  • frostyyfrostyy Member Posts: 52
    Thanks for all of the responses. Based on the info so far, it sounds like the cold won't be prohibiting me from ordering one and trading in my 04 Grand Cherokee. My dealer in Ontario claims that they have been tested in winter conditions and performed satisfactorily so I am going to hope for the best...

  • bullheadbullhead Member Posts: 125
    Well... you'll be lookin' mighty fine on that scooter, Sailor !
    Going my way (ugh!) ??? Unfortunately, I neither wish to get frostbitten nor contribute to the roadkill. However, our '90 Subaru at 35mpg is mighty nice to have as a second car now.
  • tired_old_davetired_old_dave Member Posts: 710
    Thanks for the response.
    What is your current mileage? Was performance better than new after the egr was replaced like some posters say? Did you have the turbo overboost and egr codes set and that got you the "new" egr or was it the same pierburg that was on it like someone else posted with 1/16" of ? locking the egr open?
    I'm asking because I believe someone posted their egr was replaced twice.

    Near 11k miles now. Additives all the time to complete combustion and hopefully help the egr. Jan 21 build date and the original egr. The heat issue was just now experienced only twice. I got a ding ding for the Kawasaki response. I also remember something about hot now being 259F. That seems very high. I'm going to try not to have my gauge "adjusted".
  • sailormonsailormon Member Posts: 48
    You have a point, however I run away from cold and snow. I did ride a 175 suzuki all winter one year here in N. MI. which was a bruising experience.
  • larneslarnes Member Posts: 59
    Since the Liberty the only American diesel except for trucks, I'm more interested in ride quality than off-road prowess. I know the car is tightly sprung, but hopefully it rides half-way civilized on the highway. Like most SUV drivers, I never intend to go off-road. I just prefer a car higher off the ground because it's easier to get in and out of. Something you appreciate more and more as you get older. Anyone have any comments in this area?

    Thanks for any input.

    Larry :)
  • anomiousanomious Member Posts: 170
    Hi Larry, you'll love the highway ride. It is firm but not harsh. It's a heavy vehicle and it rides like one. I'm 5'5" and have to slide off the seat to reach the ground. Being a senior citizen, I do like the height! Good luck with it!
    Larry too! :D

    P.S. I run 36 psi in the tires.
  • anomiousanomious Member Posts: 170
    Hi! Check this out! Summit.com ....search transmission coolers.......page11
    Derale heat sink cooler....measures 3x3x18" It is not a tube and fin type of cooler, should be much stronger. It will fit nicely on the outer side of the frame rail under the passenger side. It's away from the HOT radiators and things and isolated from the exhaust by the frame rail. It is right next to the transmission.
    I intend to put 2 of them in series and series them with the factory cooler.

    Let me know what you think! LK :P

    note! It will be up and out of the way of rocks! :D
  • sailormonsailormon Member Posts: 48
    Good idea, however under your suggested page I found electrical. I searched and found summitracing.com which had what you found at less than $100.

    Try this link. It's Summit Racing Equipment. I have purchased the B&M plate HP oil coolers for other vehicles and they have preformed very well. This unit might be easier to mount. :)
  • sailormonsailormon Member Posts: 48
    I for one am going to also mount a couple. Going through mountains twice a year with heavy tow i believe these will help. They look rugged and should work. I will need to wait for my new lib mid sept to measure up. BR thanks for the tip.
  • bullheadbullhead Member Posts: 125
    Great find on the Derale transmission fluid heat sinks !
    It will be advantageous to mount them where convective cooling is maximized.
    Otherwise, it would be nice to mount them out of the airflow of hot pavement, at least to an extent.
    What if one were put one (or two) in a controlled forced-air duct (w/ 12v auxiliary blower).
    Would that be a better solution in northern/ high altitude situations ?
    I'm a rank layman in automatic transmission knowledge, but am thinking the fully compulsory cooling solution may have unintended consequences in very cold weather.
    Otherwise, this is a winner ! :D

    Hello,
    New to your board and very interested in Liberty CRD. Live at 8500 ft in Rocky Mnts and will be driving vehicle 90% of the time up here. Do any of you know how this engine performs at high altitude ( up to 10,000 ft)? Plan on actually using it off road to explore as well as commuting. Other concern is my short drive time to work ~ 20 minutes one way.
    Took for test drive yesterday and was impressed by power going up mountain, as well as how well it regulated speed going downhill. Just sold my RAM 2500 w/cummins diesel and am missing the power but not the noise and smoke.
    Replaced w/ 05 Laredo 8 cylinder and am unhappy with performance going up and down these montain roads. Not thrilled about ride when 4 wheeling up to the local fishing hole either.
    Would appreciate any and all feedback!
  • caribou1caribou1 Member Posts: 1,354
    What will happen during winter if you don't have any temperature control over this extra heat sink? It sure is beautifully made but it seems to me you will never get the fluid warm enough and the tranny may not shift well. Unless you sleeve it when it's cold outside or when you're not towing?
  • caribou1caribou1 Member Posts: 1,354
    I drove mine several times between 2,500 and 2,750 Meters. It clearly doesn't pull as well as near sea level but I am able to takeover most of the other diesel suv's. The temperature needle barely moves by 1/2 of it's thickness. Here we can only access 10,000 ft passes during ~one month in the year.
  • dfw2dfw2 Member Posts: 11
    Hermit,

    I live at 7,300 feet, and have driven up to 11,000 feet through the tunnel on I-70. Stays in overdrive the whole way. Most of my driving is at high elevation, so I was interested when I drove it to near sea level this summer. With gas engines, you notice a big surge in power at lower elevation compared to what high elevation. Not so with the CRD. I assume that the turbo adjusts by increasing boost at higher elevations to maintain low elevation performance. Don't know if it does, but it seems like the power is the same at any elevation
  • bullheadbullhead Member Posts: 125
    That's what I wonder about too. Put it in a 3-4" PVC pipe and duct in cabin exhaust air via a control damper ???
  • jsymskijsymski Member Posts: 18
    I just had the TSB applied. I went camping this weekend w/my 4300# trailer. Though I didn't get to the "H" I did get close... I'm betting the TSB did not correct the problem.

    To closely monitor the temperature, I've installed an independent digital gauge. I've also installed OBD software on a notebook computer, monitoring the temperature from the vehicles sender. They were pretty much the same.

    The highest I reached was 225F on the independent and 231F on the OBD. The vehicle gauge read just past 3/4. When it started to get hot, it went from 175F to 225F in less then 30 seconds. The load was reduced and the temperature went down.

    What was different in this trip was the outside temperature and terrain. In previous trips the outside temp was above 85F (this one it was 65F). The other trips were longer which meant more frequent and longer grades (slight grades).

    I still have my Arbitration Demand in. I intend on placing it on hold until next Spring/Summer. In NH, the Demand can be brought at ANY time during the warranty. In this case, DC had their last chance to correct the problem. If next summer the problem returns, I'll go to a hearing. Since the problem ONLY occurs during towing and I wont be towing until next year, I see nothing to loose... I'm hopeful they can correct this problem. I like the vehicle if it wasn't for this.
  • mdamickmdamick Member Posts: 277
    What OBD software are you using?
    If 259 is where the unit is overheating, 231 @ 3/4 seems to be an accurate reading.
    I have noticed that when the gauge jumps, it goes quick.
    I think the heat load from the intercooler and the A/C is just too much for the system to handle.
    A thermostatically controlled oil cooler might be an idea to cool these engines down.
  • kyjeeperkyjeeper Member Posts: 31
    Went to fill Jeep up and blow build up out.At a100mph this thing is still changeing into another gear went on up to about 110 and let off, this Jeep will fly. I bought a bottle of stp fuel injection cleaner @ a bottle of redline later and put it in. I drove today about 210 miles used about a little over a 1/4 tank of the treated fuel the Jeep ran perfect, I honestly think the fuel is no good around here.Have about 3000miles on now. So far so good.This whole thing might sound stupid,but at least I am trying to figure out why this Jeep is not running right between 50 to 65, No one else seems to know.Maybe it is water in fuel, dirty injector, Egr value, too much driving in town. It was dirty and I wash it , Maybe it just needed some loving who knows.
  • gonedieselgonediesel Member Posts: 7
    :lemon: Hey jsymski, what software and linkage are you using for your jeep. I need to get a hold of something like this. Thanks, GD
  • larneslarnes Member Posts: 59
    Diesel engines combust differently than gas engines. Only air is drawn in and compressed. Then the fuel is injected in and combustion takes place do to the the extreme compression. I can only assume that at high altitude, since the air is much thinner, the compression may not be as high as at lower levels where the air is more dense. But, not being an expert and not owning a diesel (yet) I'm only guessing. I'll bet I'm pretty close, though.

    Hope this helps.

    Larry ;)
  • anomiousanomious Member Posts: 170
    Hi!....Yes, but!! The compression ratio always remains the same...With a normally aspirated engine the air will be expanded and less dense at higher altitudes due to the reduction in pressure. Now we introduce a VG turbo! Lets say that DC has set it to boost to 12 psi. and that this boost is monitored and controled by the computer... With the piston at the bottom of the intake stroke you will have an air pressure of 12 psi at any altitude (within reason!) therefor the performance will remain constant.
    Larry too!
  • anomiousanomious Member Posts: 170
    Hi! I think that you will find that the "poor running" is the transmission problem that we have all been discussing. Mine starts going bad at 52 mph . TSB 18-018-05 is the one that's said to be a fix. I have not had it done yet and I do have my doubts.

    Good luck, LK
  • caribou1caribou1 Member Posts: 1,354
    I was thinking one could isolate the exchanger with the material made by this firm:
    http://www.armaflex.com/
    They use a closed cell structure for the foam you put around cooling/heating pipes, so the salt would not get into the foam during winter. Corrosion seems a possible issue if the heat sink is not protected.
  • towwmetowwme Member Posts: 52
    Four Wheeler Magazine in there February 2005 Issue tested the CRD in their FOUR WHEELER OF THE YEAR, they stated "The turbo allows the motor to remain largely unaffected by altitude" they go on to mention 8,000 and 10,000 levels. They didn't rate it well in the contest due to brakes (3-channel ABS) and the transmission (not a manual) they mentioned the NSG370 would be better, and it gets stuck easily. Of course, I gather from reading there magazine (15 years now) they don't like the Liberty in general. I have a CRD and its the best 4WD I have had, Isuzu Trooper, Suzuki Samari, Chevy Tahoe, and Mitubishi Montero Sport. :)
  • hermithermit Member Posts: 15
    OK, bear with me as I am not familiar with all these terms that are listed here....
    What does the EGR valve do? Layman's terms please!
    What is the NSG370 that was mentioned above?

    If I am reading all of these posts correctly, the big problems are the EGR valve; overheating;poor running transmission.
    Now that we are in September, do the mechanics know how to deal with all of these problems?
    Thanks again, Hermit
