Just type it in on you-tube, why read about it when you can watch it in real life its like face to face. It's easier to change than most other vehicles due to the front facing motor design, you need a special dampner puller you can buy it online for 80 or less got to search for it, and the rest is just depending on if you work on vehicles what your abilitys are under the hood. Mine aren't great compared to some I am entry level technical, but was more than able to get it done. The timing belt on my car I replaced at 125K miles and it still looked like it could have gone longer, the factory belts on these cars look better than the aftermarket ones. I would still do it asap though, and remember get the kit with the pulley and add a new tensioner better be safe than sorry, and do the water pump since you are there, it doesn't cost much to buy. You can get the whole package on e-bay cheap, and the puller too I bet. Internet is great anybody now a days can be an automotive parts changer by watching you tube. Just the diagnostic and basic knowledge people lack but you can pick it up there too, I wish I could get my money back from that technical school. I would have just sat at home and watched videos.
The only problem I ran into with the 3.5 was keeping the marks from moving off center on the cams, I saw a video latter on someone ran into the same problem and showed a neat trick as to how to correct that it took him a couple times but it took me a whole weekend to do it, sure wish I had seen that video. I wouldn't have wasted 2 days playing around with it calling people and what not, at least you can see it and you got room to play with, not possible with some other cars, I'll take an LH anyday over few of these other ones. :thumbsup:
