If you want OEM parts, you can look up numbers and (undiscounted) prices at Factory Chrysler Parts.

If you want aftermarket, use RockAuto.

Only one issue, the v6 doesn't have a timing belt.

He would have figured it out.

Also, it has two tensioners and they are unique to each side.

If you have an earlier liberty you might consider pulling the passenger head and having the intake seats replaced. #2 is known to drop. You will be so far into the engine replacing the chain that all you have left to do for the head is the 10 bolts, the exhast manifold and the cam sensor.

Well it's nice to find this out. It's my first jeep and I live in the middle of the bush in Zambia. So it's a bit hard to bring into the dealership. I'm trying to bring the parts in through my friends coming in from the states or South Africa. So if anyone has replaced the timing belts before that could give me some pointers would really help. Thanks.

You have the FSM (factory service manual) for the 2002 model year, yes? Also, it uses timing *chains*, not belts.

From what I understand, it's a very time-consuming job because you have to tear into so much of the engine, but as long as you're methodical and are able to give it the time it needs without rushing, it's not overly difficult. I believe it may require some special tools though. The FSM has full details.

AVR thanks. I unfortunately do not have the service manual. Would I be able to download a diagram or a adobe service manual or something.
I have emailed the jeep dele airship in South Africa to see if I can get the parts from there will be allot cheaper than here.
If there is anything else you can think of I will really appreciate the help. It's just a drag trying to find people here that actually know what they talking about, allot of them just talk bull here in Africa and think they know everything. That's were I got the idea that my jeep had a timing belt and not a timing chain. Once again thanks. If I'm sitting with whole bunch of bolts in my hand flyer the job you will be hearing from me. Well hopefully that does not happen. Cheers

I think I found info for the service manual in this thread:
http://www.jeepforum.com/forum/f28/l...anuals-801654/

There are a couple of special tools I went ahead and bought. The valve spring compressor, which I later found out from my engine builder there are more generic versions of and the cam wrench. This holds the cam in place while you torque the end bolt down.

I have not acutally replaced the timing chains. I have done tensioners and I also had to pull the head which meant disconnecting the timing chain.

Googling will find you lots of vendors of instant-download PDF service manuals, and you can also find them for free if you look in places like Scribd. Don't attempt to do the job without the full factory procedure.

Unless you are having a problem, there is no need to replace the timing chains on the v6 engine. The four cylinder gas(petro?) and diesel engines have belts that require replacement.

Ok great the reason why I was wanting to do the timing chains replacement is that I have a rattling noise coming from the engine bay. I've check everything else and even taken of the serpentine belt then ran the engine for 2sec and the noise persists so the only place I can think of it has to be the timing chain or the tentioner the motor run perfect idles fine and no issue with a loss of power. What do you suggest I do. Can I just replace the tentioners or do I have to do the chains as well?

You can replace just the tensioners, but usually its a good idea to replace the chains and guides as well. The chain that runs the balancer shaft from the crank lacks any of that, it'll be the two that run your cams. One of the biggest problems I have seen with this engine and the 4.7L is people not lining everything back up, so be extra careful.
