First off you have a jeep - bad fuel economy is part of the deal. Youll be lucky to get much better than about 17mpg. Sorry to be blunt but if you didnt want heavy fuel costs you shouldnt have bought an American vehicle. For various historical reasons mainly related to cheap gas prices in the USA American cars are notorious for higher fuel consumption than equivalent European or Japanese cars. Secondly
Last tune up Spark plug choice & interval changed are a big part on liberties...Id say on avg for a stock Libby you should be around 15-17 city depending on driving habits and conditions. Edit No chips period. And if youre not familiar with cars talk to a friend or family member and get a recommendation for a shop to take it to. For a technician to tell you it could be O2 sensors catalytic convertor
Hi Thanks for your suggestion but why do I have to change the trans cvs etc. I would have thought the that the running gear is the same. I relies the engine ecu engine wiring filler neck will need to change. Im sure the clocks have the diesel lamps and the engine wiring will plug into the the existing loom once Ive unplugged the petrol wiring loom. So has anybody done this or works on them and would know..... Thanks again for you input........

I really hate it when I have to agree with you TJKJ... Unfortunately he is exactly correct. The transmission might be the same but the front suspension is different to accommodate the much heavier motor. The engine computer and transmission computer are different (separate) unlike in the petrol version. The Body computer is also programmed differently. The dash cluster is different as well having extra
Update on this.. It seems that the engine miss has returned. I had another look at the ignition coil yesterday and again the 2nd Cylinder terminal looked off colour when compared to the others. I gave it a clean but still no luck this time the miss is still there. It looks to be the 2nd cylinder that has the issue with the spark plug to this cylinder being black and dirty compared to the other 3. One thing I forgot to mention before is that the battery light came on due to having the hazard lights on for so long. Could my battery be the issue Would this not affect all spark plugs and not just the 2nd cylinder one So here is a list of work already done. Cylinder Head Gasket replacement and Cylinder head skimmed. Oil and Filter changed New set of spark plugs Compression test done on all cylinders and compression check is fine. Checked the HT leads and they seem fine. Not tried the swapping the injectors yet. Not sure how easy this would be. Again any help would be greatly appreciated Cheers Nige jeep cherokee 2.4 Sport UK Spec petrol 50k mileage
Thanks merlin Iv googled your EVAP whatsit (never heard of it before) Quote The ORVR (On-Board Refueling Vapor Recovery) system consists of a unique fuel tank flow management valve fluid control valve one-way check valve and vapor canister. The ORVR (On-Board Refueling Vapor Recovery) system is used to remove excess fuel tank vapors. This is done while the vehicle is being refueled.. Fuel flowing into
I occasionally got that problem with filling up mostly in the first couple seconds. I thought it was a problem with their pump. There are some fuel lines under the drivers side in the US version that look like return lines. There was a small section of hose connecting the two sections right around the transmission area this was very cracked and almost falling off on my jeep. I replaced this line easy
Hello 1) I was lead to a website which listed every 100% gas gas station in the USA. Every one visited was closed. South from NYC into So. Carolina and west from the same point to Nashville TN. Easily 20 of them all closed. Also EVERY fuel pump in Vermont has a black and white sticker on it saying there is no corn in the fuel (Im paraphrasing). The stickers look like the old CONTAINS LEAD stickers
This is definitely good news. Check out this press release from DC late yesterday... Strong Sales Mark Launch of jeep liberty CRD As DaimlerChrysler Tests U.S. Market for Diesel Vehicles LOS ANGELES June 7 PRNewswire-FirstCall -- Launch of the 2005 jeep(R) liberty CRD the first diesel-powered mid-sized SUV in the U.S. market has been met with strong customer response with vehicles moving quickly out
I bought my CRD liberty because roads are a mess here in my country (i live in Chile and specially after the earthquake) and gas (or petrol) is much more expensive than diesel. (gas is 2.1 USD per liter) I think you guys in USA dont have the diesel version because it has a problem with emission standards. A little bit noisy yes. But nothing serious. I installed an ipod integration kit I recommend it.
I have a 2.5 CRD and have driven the 2.8 CRD. Unless you have lived with the sound of a oil burner before you may be very disappointed its not as nearly refined as jeep would claim. The fuel consumption figures they quote are wishful thinking as well If you like covering the cars behind you in smoke as you pull away from the lights then the CRD is the one for you. If you want quite and refined cabin

Pleas help - newbie here Im about to buy a cherokee (thats what we call the liberty in the UK) and was wondering about MPG. I the brochure it states an average figure of 26MPG. I reading here that some of you are getting 20MPG Is that with a 2.4 petrol or do you have a different engine in the US Cheers

oil analysis is the ONLY way to extend beyond highest recommended OEM oil change intervals. It is true that quite a few SEMI owners have gone into the 300K range without changing the oil but that was with bypass filtration and oil analysis. Amsoil recommends changing at the HIGHEST OEM interval unless oil analysis says you can go longer. For the CRD that is 12500 miles. Ive got an 06 CRD liberty
before using the full synthetic. . The Corvette and Viper both come off the assembly line with synthetic as do many European cars. The tolerance in modern engines is a great deal tighter and requires less break in. What you dont want to do is change a tired old engine over to synth after a hard life on petroleum based oil. Ill do the first oil change at 1500 miles and go to synthetic in the jeep.
I have done two extended runs in my CRD in the last year. In the first I averaged 28mpg over 800 miles of mostly highway driving. Last week I drove 600 miles only stopping for fuel at speeds generally around 80-85mph and turned in 27mpg - This included driving through the Alps as well as highway. jeep was not fully loaded but had a fair bit in it. I am certinly pleased that something that heavy and

[QUOTEDrBrian722]I dont know for the whole USA but in CT MI and DC (where I have been recently) diesel is MORE expensive than 87 petrol. And in CT it is more expensive than 89.[QUOTE] Im reading that in most areas diesel fuel is at least as expensive as gas and in several areas costs more than gasoline. Dont forget that at least six states forbid the sale of the liberty diesel CT VT NY MA and two more.

intercooler EGR and associated hosing as well as the intake manifold were seriously gunked up. They also told me that the only CRDs they have seen with such gunking had used some form of bio Diesel or straight vegetabel oil. Also told me that after they were cleaned up and no further use of bio stuff they had no further gunking nor EGR problems. We have never used any form of bio stuff in the liberty
Some interesting info on ASTM D 6751 Quote The Biodiesel Standard (ASTM D 6751) All engines are designed and manufactured for a fuel that has certain characteristics. In the US the industry organization that defines the consensus on fuels is the American Society for Testing and Materials (ASTM). In the case of diesel fuel (and biodiesel) the responsibility for setting standards lies within ASTM Committee

we tend to refer to the mechanism that propels a petrol or diesel vehicle as either a motor or an engine....either term can be used. Here we have some weird new descriptions....that which in most Countries is referred to as a traffic light...we call them Robots...I have no idea where this came from....confuses the tourists no end. I hope this discussion helps the topic originator to repair his jeep...definitely
The CRD might not be for everyone but after having one in the family for 6 weeks we are pleased with it. Its the family 4 door grocery getter and future baby buggy. Sounds like a tractor Well it is a diesel so youd expect engine clatter compared to a petrol engine but once warm and crusing at high speeds you cant even hear the engine which is better than I can say for some gas engines. Its got good

Now looking at your signature a little closer and I see the all important K after the U. Now I realize that this is a guy who has actually scene a diesel engine before. Please except my sincere apology for the doubt and also the understanding that most diesel techs in the states have scene less engines than I have. I am going to checkrepair the seals on the EGR pipe and install the CCV filter to clear up this problem and other future problems. The car was bought with 40K on it. Has Chrysler been covering the cleaning under the warranty Otherwise I will wait to do these mods until it is warm out and I can take the intake apart and give it a good cleaning. Hi To be honest the same could be said about our UK techs on petrol models as 90 -95% of our jeeps are diesels. Thank you Regards Merlin
The CRD engine is brilliant and cannot be linked or blamed for torque converterball joint brake pedalor transmission faults. This engine is also fitted with a viscos coolant heater and believe me they warm this engine fast. Also you will find they are fitted in the famous london taxis and the ldv maxus van range not with highway use only in mind.they use Bosch injection equipment any diesel tech will understand.NOT throttle bodies like petrol engines. buy one you will only need service items.
There have been pictures of a longwheel base Wrangler (longer than unlimited) which jeep are trying to sell to NATO which has a single fuel policy. If it aint diesel then NATO wont buy in to it so maybe you wont have to wait that long. Apparently the Hummer got a bit of a slagging from troops in afganistan as it was not able to handle the trails (too wide). In base terms the CRD is not worth the extra
battery is less than a year old had no corrosion around the terminals (its only just been serviced and so the terminals have been cleaned and given a fresh coating of petroleum jelly) and was showing a green dot so I gave the connectors a jiggle and they were fractionally and I mean fractionally loose. I tightened the nuts - single quarter-turn each - and it started the moment I turned the key. jeeps

So he got down to the throttle valve and gave it a clean out that seemed to help a bit but still not great he then removed the idle control valve gave that a good clean up and put it all back together and it started first time and is running like a dream - I havent had a chance to give it a long run yet have only driven a few miles to work but its seems fine. Ive had the jeep
PL25230 or L25230. Local store had it for 5.99 and Mobil 1 0-40W was on sale for 3.99 ea. So 7 qts and filter cost about 34. . I get the genuine Mopar filter from the dealer and i pay exactly 10tax for it. I see it lists for about 12.50 from Mopar but obviously the dealer parts man i frequent gives me some off list. This can be really important especially when you are buying accessories for your jeep.

Fuel economy seems close although I have not done exact tests - as my driving patterns are not the same all the time. But we average about the same no matter which fuel we use.... Your driving style will impact the fuel consumption much more than the use of Biodiesel. Does biodiesel provide similar miles per gallon torque and horsepower as petroleum diesel I have to say with only B50 in my jeep there is a noticible differance in power like 10-20% and I get .5 MPG less also.
I just want to help anyone with startingrunning issues so they dont have to go through what I have.. I have read countless threads of people having similar issues with no fix. If you are having any drive-ability issues(cold start hot start limp random codes p0093) I would start with the injectors. Have them tested. Replace that filter with something better. Now I just have to replace a glow plug 2

While its warming up you might as well be getting down the road -- saves time and gas and warms
