I'd like to proceed and get it running properly without the engine light on and without the constant hesitation and smoke.
I live in upstate NY and my dealership are generally clueless about the CRD because there are so few of them here.
Looking for suggestions. Thanks.
To get around the MAF sensor engine light thing. Remove your computer and send it to Green Diesel for the GRD Eco tune ($450). this will also increase your power and MPG, Controls the sensor without having the engine light on.
To keep all the oil Gunk from stopping up your engine, buy and install a Provent 200. It will collect all that gunk instead of allowing it to settle in your hoses and EGR valve.
I bought my 2006 in August and did alot of reading on the different Forums. I got mine at a great price so, It did not bother me to spend the cash immediately to make it last longer and get the Best MPG I could.
A Transgo shift kit for the transmission is another highly recommended addition, as is a fuel lift pump.
You can google the Jeep manufacturer, give them your VID # and ask if it is current on all the Recall's.
Have Fun! Bob
If you havent installed a Provent now is the time. I get about an ounce of oil per 1000 miles out of it. Most of that will end up in the EGR valve and intercooler without the Provent.
2005/85K CRD. Glow plug light does not come on or only gives you a 1/10 second blink.
The engine also occasionally stops shortly after start up but restarts when fuel is hand pumped to a point where the fuel bubles? from one of the electrical sensors at the top of the pump. The engine also will occasionally start normally and then loose power until it is shut off and restarted (loss of turbo corrected by computer reset?). The crank time before cold start has increased significantly in recent months. The check engine light does not stay on and no codes come up.
As to the glow plug situation, glow plug duration is pretty much or mostly dependent on the temperature of the engine. If the engine has been sitting overnight, and ambient temperature is fairly warm then the glow plug light will only come on for a split second. If the temperature is really cold, then the light will stay on for up to two to four seconds.
I would replace the fuel filter mounting/manual pumping assy. There have been recalls on them because of air leaks cracks etc. I believe this would take care of the need to pump up the fuel system.
The glow plug system generally only blinks on in moderate temperatures. My 2005 little gold coil indicator lamp only stays on for three seconds when it is Zero degrees. However, if you just want too replace the glow plug module, it is a pricey plugin. No labor for someone who has the complete compliment of thumbs.
Cheers!
Has anyone found a method to keep the springs and links from rusting away? Has someone come up with an after market replacement. "Ya know, sometimes ya just can't fix Stupid" and maybe the answer is to remove stupid from the rear brakes completely.
If not the up-grade replacement for the complete asembly is the Racor 245R.
AIr leaks into the fuel system (unfortunately) are fairly common. The "banjo" connections back by the fuel tank often will allow air to be sucked in as well.
Many have replaced the In tank float assembly with one that has a fuel pump in it out of a 2002-2007 Dodge Diesel truck (I did). this pressurizes the fuel system so no air can be sucked into it.
The CRD is a really neat little vehicle, but Jeep did some cost cutting and added Smog crap that it was not designed to have. If you read the forums there are several very progressive back yard mechanics that have brought these Liberty's up to their true potential. I followed their advise and made most of their recommended aditionas and subtractions right after I bought my 2006 last August.
Don't give up on it, just jump through the hoops ASAP and then enjoy it for years.
Never had an over pressure code and do not have a Provent. I have very little dirt/oil in the hoses to and from the CAC and I have cleaned the CCV at least once with some solvent. It had very little residue in it. Have 75.5K on the CRD and it runs fine. Need to change the serpentine belt though as it it is slipping a bit.
You may be due for an alternator change if you hear the serpentine belt
Observe the front of the free spinning pulley of the alternator: if it collected dust or brownish powder/residue this is a $500 warning. I also suspect the bad rectifier of my alternator shortened the life of my battery...
Since I replaced my alternator (more than a year ago) the pulley remains clean. You can disconnect the 'Field' of the alternator to compare the sound produced by the serpentine belt. When we had Vee belts we could not do this so accurately.
I bought a Provent and never installed it; I also think that a better quality synthetic oil such as a 5W40 keeps the engine clean during 15,000 miles intervals (in my case).
There is no residue or dust anywhere near or on the alternator or it's pulley. The squeal comes when I have run the Jeep for a while and I goose the gas for a bit of power. The sound is not always present.
The belt has over 40K miles on it and there is some glazing on the smooth side of the belt and a few small cracks on the grooved side of the belt so it is time for it to go. I am going to change the belt this weekend as I have a long trip coming up in a couple of weeks. I will probably get the belt at NAPA. I have had good luck with their belts.
Just need some pictorial instruction on how to remove the upper fan shroud.
I don't need to remove the fan shroud to replace my serpentine belt; is your different?
My shroud was removed for the timing belt change and the air conditioning pipes were severely 'tortured' to save a few minutes of work :sick:
Is the glazing continuous along your belt? If so, one of the pulleys could be out of alignment.
Your alternator voltage should be 14.3 volts before you hit the road :shades:
The smooth side of the belt has a shiny look to it but the side with the grooves has numerous cracks and looks rather dry.
Voltage on my alternator is 14.4 volts.
If you have a 12" handle on your ratchet this would give you sufficient leverage. To clear your hands from the pulleys use either a deep socket on a standard ratchet or a swivel head ratchet with a shallow socket to avoid ripping off the tensionner.
Once belt tension is released (while you apply force with one hand on your ratchet) pass the belt over to the other/outer side of the pulley below the alternator and release the tensionner. Repeat the previous step after repositioning the angle of the ratchet; this will reduce the amplitude of the swing you need to compensate.
You will get dirty for sure, but this is a safe way of doing it.
I learned this procedure because the Jeep dealer had not repositioned my belt correctly after the timing belt change. They had left the belt running on the outer side of the pulley below the alternator and this made it squeak as you described the symptom. Good luck :shades:
Thanks for the information. Will a standard depth socket work on a regular ratchet? Maybe I will purchase a 3/8 inch swivel head ratchet as it is tight in there. I have a piece of pipe that I used on a previous vehicle to improve leverage when I changed the belt on it.
Two days ago I had the transmission serviced, both filters and replace four quarts of fluid. I had gone 5000 miles over the recommended interval. The fluid was a little dark but there was no sludge or residue in the pan. The magnet in the pan had only a very few particles clinging to it. Cost about $100 for this, including parts which I purchased.
If you purchase a swivel head ratchet, get one with a long handle. You need stability when you hold the tensionner with only one hand; in this case the short socket is preferable to the deep one.
When you combine narrow access along the fan, a long socket plus a swivel head there is an angle at which the tool becomes unstable and folds.
My manual says the synthetic transmission oil is kept for the life of the truck. It was chosen for not retaining moisture nor allowing sludge formation due to it is hydrophobicity :confuse:
I will purchase the swivel head ratchet to use with the short socket that I already have. I will use the piece of pipe I have that fits over the handle for extra leverage.
As to the transmission fluid, a synthetic is required namely ATF+4 or equivalent. Chrysler still requires that it be changed at 30,000 mile intervals over on this side of the pond. Some companies like Amsoil, make a universal fluid that that works in some Fords, GM and others beside Chrysler. I used this fluid in my 1993 Dodge truck with good results but that transmission could also use Dexron fluids too so it did not matter that much.
As to the differential fluids, Amsoil says their Severe Gear fluid is good for 100,000 miles and the tech at the dealer I use says that under certain conditions that would be so. The tech suggested 50,000 miles and no more than that.
I cut away a portion of the upper fan shroud so I could access everything. The belt takes a really circuitous route around the pulleys. The old belt had 40,000 miles on it. The smooth surface was shiny but not glazed. The grooved surface had multiple cracks in it some going to the fabric belts. Good thing I got rid of it.
I will reattach the removed portion of the shroud with some pieces of aluminum and four screws and bolts.
Tonight, both lights came back on and the CRD wouldn't drive. It would shift to drive, but the engine would just rev.
Is there a safety net on the Liberty that prevents it from driving if there is a brake warning?
Dealer fixed those THEN called saying they STILL have a leak and suspect the engine rear main seal (which I had asked them about when I took it in). I am in Cal-e-fornia and since the CRD was never sold here I always get "we have never seen this before" story. Our's is the ONLY CRD this dealer has ever seen!
They are suppose to have the vehicle back together this week. They can't tell me if this is a problem we can expect to see again since "they have never seen the CRD before".
Had the fuel filter assembly replaced last year after OBD kept reporting related failure codes. The new filter fixed the problems.
Price of diesel is now greater than $3.00/gallon everywhere south of Virginia. Regular gas is about $0.20 (average) less per gallon. As I see it, diesel fuel is still a good bargain.
In Monday's USA Today (11/22/2010) there was a small article in the business section that might be pointing to higher diesel fuel prices. The mainland Chinese intend to import more diesel fuel as their refinery capacity cannot keep up with demand.
Thanks
Also a note not to rotate the crank counter clockwise.
NOTE: Rotate the engine by the front crankshaft
bolt until the witness mark next to the bolt in the
front crankshaft hub reaches the 12 o’clock position,
or TDC. Rotate the engine another 1/4 turn to
the right, rotating the witness mark to the three
o’clock position, or 90 degrees ATDC.
(3) Rotate engine by hand until the witness mark
in the front crankshaft hub reaches the 3 O’clock
position (Fig. 145).
(4) Raise and support the vehicle.
(5) Remove the splash shield.
CAUTION: The engine block, flywheel, and/or flex
plate, has an alignment hole to assist in properly
aligning the crankshaft before service. Failure to
properly align the crankshaft may result in improper
valve timing and engine damage.
(6) Insert the long end of a 6mm Allen wrench into
the 90 degree ATDC access hole on the right lower
side of the engine block. The engine is aligned properly
when the short end of the Allen wrench is parallel
to the rear of the engine block. (Fig. 146) .
(7) If the small end of the Allen wrench protrudes
away from the engine block (alignment hole in the
Don't panic if one of the driven pulleys spins free when after the belt is removed; the timing is related to the diameter of each pulley and number of teeth (distance) between timing marks. Good luck.
After owning my 05 Liberty for 5 years, I traded it in this weekend for a Ford F150.
I loved my CRD but felt it had become a pink elephant with little or no support from Jeep.
Good luck and thanks to all who support this forum.
They recommended that the water pump be replaced at the same time, as it is mostly the same procedure. My own forensic study of the pump indicated that may have not been needed. The pump is very well manufactured.
Procedure (2.8l diesel)
1. Remove cooling fan and shroud. The fan assembly is best
removed with a very large crescent wrench on the nut just behind
the fan viscous coupling. Then hit the wrench in a counter
clockwise direction with a small sledgehammer. It may help to
spray with penetrating oil. Worst case, wedge something behind
the fan drive pulley to keep it from rotating and then use the
sledge method.
2. Remove accessory drive belt.
3. Remove both idler pulley (right hand thread, 16 mm) (a), power
steering pump (3 bolts that you get to by rotating the pulley, 10
mm) (b), accessory belt tensioner (c), cooling fan pulley and
bracket( 4-13 mm bolts) (d), crankshaft pulley/damper (4-10mm
bolts, you may need to hold the pulley by the 21 mm center bolt)
(e), and alternator (2-13 mm bolts on the front and 1-15 mm on
the back side-note you will have to loosen the 2-13 mm bolts for
the bracket that holds the alternator to the cylinder head) (f) .
4. Remove the front timing cover (7mm bolt x 17)
5. Remove both plugs in the camshaft cover (one on intake side
behind alternator placement, one on exhaust side behind
thermostat area). Remove the plugs with a 5mm hex.
6. Rotate the engine clockwise only with a 21mm socket on the
front of the crankshaft until a 6mm hex key engages the hole in
the flexplate/flywheel.
7. Inspect the two openings in the camshaft cover to see if the holes
in the camshafts align. If so, install the two pins into the
respective camshaft. If not, rotate the engine 360 degrees at the
crankshaft and re-inspect.

8. Loosen the timing belt tensioner and rotate counterclockwise by
hand until slack is sufficient to remove the belt from the pulley.
Remove the old timing belt; discard when the refitting operating
is completed successfully.
9. Loosen both camshaft pulleys by rotating the bolt (17mm)
counterclockwise. It is sufficient to have them loose; they do not
need to be removed.
10. Ensure that the high-pressure fuel pump pulley is oriented
properly (see picture) and fit the new belt to the engine. Starting
from the crankshaft pulley, remove the slack out of the belt by
using the camshaft gear locking tool to pull the tension across the
pulleys. Then torque the two camshaft pulley bolts to the
specified torque in service manual.
11. With the belt properly installed around the pulleys, tension the
timing belt with the pulley as shown in the picture. If the proper
handle isn’t available, the pulley can be moved with two 3mm hex
keys. Rotate the tensioner until the proper gap on the pulley is
achieved. Tighten the center fixing bolt to 30N-m.
12. Remove the two camshaft pins and crankshaft pins and rotate the
engine 720 degrees and verify that the timing belt tensioner is
still in the proper orientation.
13. Reinstall the timing belt cover and all ancillary components.
I have a set of pictures in a PDF file with these instructions. The picutres are labed.
If someone know how I can attach the pdf file let me know and I will.
Also, Green Diesel Engineering rents the tools to change the belt I think, they charge $20 plus a deposit. Haven't done mine yet

Just want to write a brief note. While returning home from our vacation, the engine on my CRD simply imploded at 75 mph. Initially there was a bang then a washboard vibration throughout the car, loss of power steering with the Jeep pulling hard to the left. I managed to get the Jeep off of the road and limp it into a Florida rest stop. When I got under the hood, the coolant tank was empty, no oil in the oil pan and the serpentine belt tensioner had been ripped off the front of the engine. Motor oil was dripping all over the ground and the whole underside of the Jeep was covered with oil.
Had the CRD towed to the nearest dealer in Melbourne FL. There diesel tech pulled the skid plate and it was covered with pieces of metal. The front half of the oil pan looked like a sieve. There were multiple holes in the iron block on both sides and number one piston and connecting rod were gone (per the tech). The tech called Chrysler and neither he nor the Chrysler engineer had ever heard of this engine imploding like this one did.
I have 77594 miles on the car and have a claim in with Chrysler to make this right.
Thanks (formerly Winter2)
The scary part about all of this is that had any of the shrapnel had come through the back of the engine, I wonder if any could have entered the passenger compartment.
Is it under an extended warrenty?
Did the check engine light come on prior to the Bang?
Did you happen to notice if it was overheating?
What did the other 3 pistons look like?
It would be interesting to get some pics. It sounds like the connecting rod between the crankshaft and piston failed or came loose on the #1 piston causing it to break the piston apart and with the right timing when it fired the piston was past its TDC and under super high pressure the piston became a fragment bomb.
Just a guess, but it sounds good!
Please keep us posted on the final out come and diagnosis. My CRD has the same miliage on it.
Bob
The gauges and lights were all in their normal positions/states just prior to the event. Nothing was out of the ordinary. The oil pressure light, coolant level light and the CEL came on after the event had occurred. The temperature gauge was it where it normally would be prior to the event.
The service writer was able to show me one of the holes in the block near where number three cylinder would be located. The hole was about 2.5 inches in diameter and you could see into the crankcase itself.
Based on what the tech told me, number one piston and connecting rod were gone.
I have been playing telephone tag with my case manager since yesterday. I am keeping my fingers crossed.
I really wish you an efficient transaction with your case manager but if I were in your shoes, I'd be eager to play with a different Toy... Father X-mas :confuse:
I once posted this message and maintain my position:
http://townhall.edmunds.com/direct/view/.ef1454f/715#MSG715
Experience taught me not to operate this engine at a steady speed for long periods, never lock it into O/D at low RPM and high torque, and in my case check the external oil pump hoses on my original Italian engine block! Do you have the Chinese engine?
I don't believe in fatality and when a connecting rod breaks there is a reason
The engine in my CRD was made in Italy. I did not realize that this engine was not as robust as it should be. So in essence, I am dealing with a marginally built diesel engine. I find this to be disconcerting.
This was my tenth or eleventh round trip to Florida in my Jeep and it always ran smoothly and quietly. It never seemed to strain or pull that hard at most any speed. If were to purchase another European built diesel, what you recommend? I can get Mercedes, BMW and VW.
I would consider a 'Blue Motion' VW for economy and short ownership, a BMW for a 10 year sport-family utility vehicle, the MB for less demanding elderly people and the AUDI for performance, pleasure, comfort and beautiful workmanship.
Local criminals practice car jacking. They prefer AUDI so I don't want to temp them
This morning we had 32cm of fresh snow accumulated over a previous blanket of 15cm. The CRD with its second set of BFG AT tires climbed our narrow ramp (25%) without slipping and gave plenty acceleration. Driving down the ramp in reverse was trivial and braking was safe without need of ABS. Half way down the ramp I need to fold my mirror to pass an obstacle and reach my back yard so I am really concerned about grip on snow. My wife's little Dahiatsu Terios slips and twists while going down in reverse along the same ramp simply because its too light. This is why I may have to look for a mid size Toyota preferably one that has steel bumpers...
Mercedes, BMW and VW sedans need easy parking access during the snow season unless someone cleans the driveway for you. Unfortunately this does not apply here
I generally keep my cars ten to twelve years and the VW Rabbit/Golf is the one I would be able to afford. The others are just too expensive to buy/maintain. Blue Motion is not available here but 4 Motion is, but only with gas.
I can manage well with front wheel drive as we generally do not get much snow during the winter with exceptions like last season. I would use snow tires of course.
Cars with steel bumpers are now passe' here in the U.S.A. unless you drive a pickup truck, but they too are now going to plastic as well.
