    There is no pressure in the filter. They have no lift pump, unless someone added it.
    It sucks through the filter, so just unscrew it.
    Make sure you get it fully primed when replaced. ;)

    The computers used in Europe are probably the same as we have here. It is the parameters of the software that are different because in Europe they go after different pollutants than they do here in the U.S.

    What gives the Europeans better fuel economy, in my view, is that the fuel is better than here and the engines, at least for now, are less encumbered with pollution control devices. In the next few years, European pollution control specs will be as tight as what we have here.
  • I had the Blower Motor Recall taken care of back in june and I don't recall useing my electric side mirrors until today and they only work a little and then stop...I was told that they replaced the blower motor and something else that had to do with the speed of the motor because it was blowing full blast or nothing at all "which it was doing & that was the real reason I took it in for the recall"..I was charged for the part that fixed the speed of the blower only !! But I do not know why both of the electric side mirrors will only move slightly and just quit ??

    thstranger: To tell you honestly, I can't recall how they fixed the mirrors. It has been more than 4 years ago, and Chrysler bought back my CRD on April 4, 2007. My "Green Beast" was in the dealers shop 25 times in 17 months, and I knew all the mechs names by heart. Chrysler called me, I did not even think they reviewed these things!

    However our 2007 Chrysler Pacifica Touring AWD is the best vehicle we have ever owned! We got the Lifetime Powertrain Warrenty and bought the LifeTime Max Care extended Warranty so maybe this will be the last new vehicle we will have to buy. We have 76,000 miles on the PAC and it gets 24 mpg, so all in all it has been the best thing to happen to us.

    I enjoy getting up dated on this forum, and was supprised to get your note. I hope the CRD works well for you, happy driving!

  • Thank you for the reply, I really haven't had many problems other than "Recalls" and a transmission solonoid at 1450 miles..The mirrors work when I first start the Jeep but only for a couple adjustments then they won't move. I will most likely not take it to a Dealer as I'm sure they won't have any idea and will spend too much time just trying to figure out the problem, and i'm always affraid that some careless tech will screw something else up. When I got the jeep back from getting the blower motor recall done, I opened the glove box and it just fell off on the floor.The tech didn't even snap it back on so I did it :confuse:

    You don't have too. To fix all of the problems with the engine's preformance and increase milage PLUS reduce EGR valve issues do what I have done! - GREEN DIESEL ENGINEERING and get their ECO TUNE. Their engineer wrote or co-wrote the ECM program for the CRD Liberty. This ECM program still limits the torque, but only when the torque converter is locked and in overdrive, GDE's ECM engine program makes around 280 ft-lbs when the TC is locked. The F37 program limits it to 260 ft-lbs, When unlocked you have 335 ft-lbs around 1800 RPM amd 188 HP near 4000RPM.
    They also have a tune IF you have the Euro TC which does not limit torque in lock-up. D-C limited the torque as the Stock TC cannot handle all of the torque this motor can produce, hence the SHUTTER when loading the drive train. GDE's program has to do the same as the hardware can not take the loads, so to prevent damaging the TC the torque is limited. I have no affiliation with GDE, other that I have purchased their product. They are on the web.
  • Thanks Zoomy, I will look "GDE" up on the net. But how can this fix my mirror's ?

    I was responding to warren9 question on the ECM program, he wanted the European program. If someone he knew in Europe could upload their program, it then could be emailed to him; then he could download it into his ECM and then he would have the same program: assuming full interchangability. Both would need the correct hardware to do this transfer. Buying the local USA ECO tune would be cheaper. :)

    I am asuming that both mirrors stop working.

    In you case I would check the wiring in the power mirror circuit starting with the fuse, and look very closely to see if there is a relay in the circuit. The relay could have a broken winding that opens when heated dropping out the relay, or have burnt contacts. Use a volt-ohm meter to check each part of the circuit.

    When working on the blower motor the dealer's tech could have pinched a wire, after you move the mirrors do you have to replace a fuse? This circuit could also have a circuit breaker or thermo overload device to protect the mirror motors, these would also need to be checked.
  • I'm sorry Zoomy, somehow I got confused .....Both mirrors will move maybe in three different directions right after I start the Jeep, then neither of them will move again...seems like the drivers side mirror will move just a little more than the passenger mirror but not by much...I would say that they will move up,down,and maybe to the left or right and then they will not move again till the Jeep is turned off and restarted. I don't move them around often except when pulling and backing the camper I might need to adjust them....

    Yesterday I pulled the MAF on my CRD. It had a light sticky coating of something on most of the surfaces. I used MAF cleaner and discovered that the real working part(s) of the MAF had a thin black coating of goo on them. I checked the inside of the airbox and found no dirt or oil film. I use a K&N filter in my CRD. I will be driving my CRD later today and let you how the cleaning has impacted the way the engine runs.

    CEL came on early last week and I had the dealer interogate the PCM. Number four glowplug is the culprit and I am going to try to replace it myself. Do I need any special tools? I know I will need to move the fuel filter assembly.

    Thanks in advance.

    Hi winter2,
    Deep socket wrenches are used for glow plugs. The only worry is that you need to vacuum clean around the plugs prior to removing them. Any accumulation of dirt between the plug and engine will fall into the cylinder. You can take this opportunity to rinse your engine with low pressure water; most of the gunk is easily removed and the engine compartment will look new :)
    When one plug fails we usually change the four...
  • winter2winter2 Posts: 1,796
    Thanks Caribou. Do you know what size deep socket I will need? I will degrease the engine prior to doing surgery even though it is pretty clean.

    I drove with the cleaned MAF and performance was a bit perkier, the turbo whistled more freely, idle was smoother and shutdown was also also smoother. Took more cranking to get it started. I am wondering if #4 glowplug failed and took all of the glowplugs or if is the result of the MAF cleaning. I will let you know tomorrow.

    On occasion while towing a 3000# camper I experience a loss of power. If I start from a dead stop and try to accelerate quickly usually 2nd or 3rd gear is where the loss occurs and sometimes there is a jerk with the loss of power. Other times it happens at hwy speed 65-70 and I slowly lose speed and power. After the loss of power I experience the problem of not being able to rev over 3k RPM. And my speed is maxed around 25 and it does not shift. After this happens I can cycle the ignition several times or disconnect the battery and the problem disappears. Just the other day this happened and after disconnecting the trailer and driving on the HWY 65-70 MPH the loss of power occurred again. No lights come on to indicate a problem and I have not attached an OBD tool as I usually get rid of the problem before having one handy. Before going to the stealership I thought I would look here. I have seen some similar reports indicating EGR or CAC hose problems. Any help would be great, I just need to get headed in the right direction. :confuse: Thanks in advance!!

    I should add I clean the EGR and MAF sensor ( I think it is the MAF on top the engine near the back) every oil change.
  • caribou1caribou1 Posts: 1,348
    Have you tried shifting into Neutral to unlatch the tranny and a second later bring it back into gear? I had to do this a few times to get rid of a 'sticky shifting'. This could be caused by a timeout issue in the logic.

    Concerning the side view mirrors that stop working for an unknown reason, I'm in the same situation. I guess it's a cheap 3 cables construction and they got corroded over the years :confuse:
  • caribou1caribou1 Posts: 1,348
    Mine are 16 or 17 mm deep socket, yours may be different. There is no need to over tighten these plugs and I would recommend to put a drop of gun grease or 'Molykote grease' on the thread. Don't forget to disconnect the battery and look for weak (soft) spots on the leads connecting the plugs.

    Thanks Caribou. I am going to stop at the dealer after work to glean more info/tricks to make the change easier.

    I am going to use some anti-seize compound on the threads so they do not bind in the heads if I ever have to replace them.

    I find the placement of the glow plugs amazingly bizzare, under the intake manifold. I guess they had no room on top of the head.

    As to the MAF, I drove the Jeep on the highway to work this morning. Had noticeably more power and the sag at 68 MPH is now gone. Also, less smoke too considering that I have almost none. I wonder how often I should clean the MAF, maybe yearly or every six months?
  • I have not tried that but if/when it happens again I will see if that helps. I also forgot until now when I bought the jeep there was a work record for a "low fuel sensor" issue that caused a similar problem. Any idea what that might be ?

    I have read that others have use this valve, so that the threads are no longer disturbed.
    F-102(PF-3/8) Fumoto Oil Drain Valve - Ships Free!
    Change Oil Quick & Clean. Good-bye to Oil Drain Plug.
    They have them on EBAY for $27 with free delivery.

    get some Di-Electric grease, radio shack and most electronic places sell it. Whenever you expose an electric connection, put a little on it. Your mirrors sound like a weak connection. Beleive it or not, there are also people whose body chemistry screws with electrical devices, My wife is one of them, We have 5 cars, every one the window control no longer works on her side. Her gold wedding ring disolves and we have to take it to the jeweler and have it re-coated with new gold. She cannot wear a watch with a gold band, it disolves. Wierd but true.
    The Di-electric grease helps maintain a good solid connection, which will increase the life of any motor. A bad connection = low voltage, which will cause premature failure.
  • Thanks for the info Uncle Bob, I haven't tryed anything yet....where should i put the di-electric grease exactly ?? thanks again
