Remember, the first diesel ran on peanut oil not dino oil.
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.
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.
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?

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:
JSNH- 'Just say NO to homebrew'
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.
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?
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.
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.
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.
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".
Thanks for any input.
Larry
Larry too!
P.S. I run 36 psi in the tires.
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!
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.
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 !
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!
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
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.
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.
Hope this helps.
Larry
Larry too!
Good luck, LK

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.
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
