SERVICE TIME

Hello - anyone have the typical service time requirements for the 100K timing-belt service?? .Mitchell's labor guide ??

thanks, dw

With or without water pump replacement? I have no clue what "book" time is but would guess about 4hrs without WP and 5-5.5 with assuming no problems. A bit less if the fan shroud has been modified to make fan and shroud removal easier.

PM or email geordi for a more definitive answer.

Just to get it out there IMHO speaking just of the belt it's not a 100,000 mile service interval, yes I know what the manual says, rather it should be a 6yr or so/100,000 mile whichever comes first. I simply don't believe is risking rocker damage to stretch the life of the rubber band timing belt much past 6yrs hence mine was done 12/2013 at 49,675 miles at which point the belt was noticeably "harder" that the new one and both idlers were leaking grease.

Thanks Pap - This give me an idea on what I should have expected..
My CRD is in a shop currently for the belt service.. A shop I found in research of who could do this service.
This particular shop stated: 'yes' we can work on the CRD, and perform the 100K service.

I brought my CRD into the shop on Tues-7am - it is now Friday & it is still not done [they say]. All they were to do is the belt service [WP included]. I am now convinced they DO NOT know this model Jeep.. or if I will get it back in the running condition I brought it.. :5SHOTS:

the shop is - http://allamerican4x4.com/ if anyone was curious..

Did not see anything about diesel repair on their site. Hope it all works out, and let us know if they say additional problems so we can clue you in if it was casued be timing gone bad.

flman & all.. I truly am doing my homework on how to maintain this new-to-me CRD..

I just now drove the Jeep home - I insisted on picking it up today. I paid them and got out of there. Ill deal with the consequences later..

it appears as if the drive and the sound of the engine is different - is this common after this belt service? While it seems to run ok, I note it is just different. One of the biggest different noises is a 'heavy blowing' noise. Almost a high powered fan as I am on the highway. On acceleration [maybe 40mph] this loud blow comes into play not noticed before. The engine as a whole has a little more 'roar' also on acceleration - not sure if the 2 are connected..

could they have put something back incorrectly? what does the engine do if the timing belt is one notch off, one way or the other.. [might be a stupid question].

I also noticed that on my invoice, the Timing Belt Tensioner & OE Timing Belt Rollers (Qty 2) are missing off the invoice! Could they have actually done all the work and not replaced the rollers??

Now that this service is out of the way [I think] and some other issues resolved, I can get to learning and tweeking this CRD to my needs..

advise, & much thanks. dw

PS - if there is a donation section to this forum, Id be happy to donate.. this forum has been the 'wealth' the past several weeks ! :CAMPING:

It should sound exactly the same with the new TB as it did before.

They probably took the CAC hose off for access. I suspect it hasn't been reinstalled properly and is leaking air. Probably just one of the jubilee clips needs tightened a bit. If you can hear it and don't have a CEL then expect one shortly.

The idlers are required as part of the service but not the tensioner but most of us replace them all. If your unsure I'd ask for the old parts.

dirtmover - FYI.. the CAC is secure... regards..dw

If you want to give, become a lifetime member. I do not know what to say about a fan roar, but glad they got it all back together with no learning costs on you wallet.

If it sounds different (especially louder) then something wasn't done properly somewhere. The engine should sound the same, or possibly quieter. In the case of the engines I have worked on, the owners all comment that the engine is smoother and quieter with a fresh belt job.

I don't know what was done and how, but if this was my CRD, I would be planning to disassemble the front of the engine and do at least part of the job again. It isn't technically that complicated to get to the timing cover, and you don't need to take the grille / radiator / bumper out at all.

I'm concerned about the change in sound. There was something that wasn't done right. Chances are it is just the fuel pump being out of time with where it should be... But it could also be the cams or the crank. It could be anything, and it needs to be checked. As the belt wears in, the timing will adjust (this is normal) within the designed range. If the initial timing isn't done right, you could reach the end of that designed range, and the result will be piston contact and broken rockers.

I think you might want to plan to tear into it yourself, or maybe ask Sir Sam if he is in your area and can offer any assistance. Colorado isn't exactly convenient, but he is a lot closer than I am in Florida!

..it seems to run ok - it's just the noise difference.

Yes, I agree.. I might have to start working on my car again. I have to learn this engine for sure after these past weeks.. :roll:

Check the bottom of the air filter box to turbo hose just in front of the turbo for a tear. I think you can see that area from underneath but if not you may have to pull the turbo to intercooler hose to get access.

Check to see if the mechanical fan clutch has locked up. With the engine off can you spin the fan by hand, there will be some resistance but it should be moveable. Crank up and have someone raise the RPMs on the engine; does the mechanical fan spin really fast and move lots of air as rpms come up. I ask this because I ran a fixed fan, no clutch, for a while and there was a definite fan noise that was most obvious around 40-45mph

Ouch, with people in your local area who have done this job, why did you go to a shop? Did they have the proper VM timing belt tools or did they do the usual pray and mark method? Start saving up now, shop and even dealership reports/experiences on timing belt jobs do not fare well and end up costing $$$. I wish you luck and hope you are the exception.

..I was told in the end they had the proper tools for this engine, but they took so long to do the job I'm uncertain they they did the job correctly. It was too late to do anything after the fact. Honestly, i was too new to this engine - I had to trust someone to get it done, based on the ''hurry-up and get this changed" statements I got here and other sources. The Jeep dealer who is supposed to know how to work on its own cars gave me '0' confidence, especially when 2 of them seemed clueless or outright stated 'we cant work on this engine'! My past experience with the dealer is terrible, so I chose not to go there. Loaded with the info I found here, All I had to go by was the word, yes, we can do this job. "every" shop I called wanted to charge me $600+ just for a water pump, and not anywhere near the cost of IDparts's 400$ , FOR ALL THE PARTS. NONE of the shops I called said they would let me bring my own parts - obviously for the reason of mark-up - higher quality parts I could have brought in at 1/3 the cost. Lastly, I was too new to trust someone here to do it working privately that offered no warranty on the work. ..but really, how good is a warranty if you don't trust the shop.. I am not familiar here [new], and that is why I chose not to seek someone through this forum - that will change as time goes, I'm sure.

I am from NYC, and moved here after 911. I can say without hesitation, that I have yet to find any business I can fully trust in this state. I have never experienced even a 75% satisfactory job for anything in CO... NOone ever does what they say they will do, or does it correctly the 1st or 2nd time :dizzy:

pap, I will check these things, thanks !
