    I've been having a stutter from the engine while idling in gear and have replaced plugs & coils to no avail. I did some research and have come to the conclusion that my timing belt could have slipped. I would think this to be unlikely but I am approaching 250k miles and to my knowledge the timing belt has never been replaced. I've bought the Gates TCKWP298 timing belt kit and will be working on it this weekend. I'll only have 2 days home from college to get the entire job done. Does anyone have any pointers? And is it possible to change the timing belt without removing the A/C compressor? I'm also not certain about lining the belt up. I know the mark on each pulley should line up with the I mark, but I've seen some people line up the marks on the belt with whichever letter is to the side of the I, while others line them up with the same I mark as the pulley. Anyone have any insight on this? Thanks in advance.

    I would say bare minimum you wouldn't want to rush this job. Toyota dealers can do it for somewhere around $1000
    You can pull one of the plastic covers back on the driver or passenger side (driver is easier) and check the belts condition. How long have you had the truck? If that belt breaks it could turn that engine into a paperweight.

    Can't recommend watching the process from start to finish so you know what you're in for. The 1st of these videos is one of my favorites giving a lot of the warnings/issues to be aware of. The 2nd video is another one that other folks around here like from a Toyo mech. Either way, if you suspect the belt has never been changed, you're gambling with the life of your vehicle every time you start it up. It takes 5 minutes and a 10mm ratched to loosen the bolts enough to pull back either of the timing covers to check the belt for cracks. Toyota recommends changing every 9yrs or 90k miles, whichever is first. I think 10yrs/100k is plenty fine and some guys have made it as long as you w/o changing for sure, but others have had their engine grenade via old belts snapping and jumping before 175k miles. It's all a crapshoot.

    Can we get these input in the info dump thread, or add them to some sticky post that references repairs?

    I agree with the above. Take a look at the belt and see what kind of shape it is in. That will tell you what your in for. It might be an easier situation to fix.
    Speaking of, have you changed the air filter? Throttle body cleaner? MAF cleaner? A can or two of Seafoam in the tank?

    If you haven't done this before, watch the videos and do your research beforehand so you don't break everything down and then realize your missing something like the belt tensioner and get stuck. Or you can have the dealer do it and take that bit of stress off your plate. Might be worth it in the short-run.

    I haven't done the TB on the tundra, but after doing it on my 4runner I would recommend buying/renting the specialty tools that are recommended. If you need the truck back up and running, don't assume you can just get by without the proper tools.

    We'd started chatting through that several months back, but I don't know where we ever landed. It maybe started with a poll, and then went nowhere after?

    Ultimately, I think we need someone in the 1st Gen forum with moderation power, but only over the 1st Gen subforum itself, I think. Someone that can talk with all of the regulars here, make choices on what to stick or unstick, and work on a few "global info" threads. Ever since Pinay left, we get stuff done when asked, but I think we need some dedicated support, even if just for a couple of months.

    Not to mention, while you'll likely pay several hundred more having the dealer (or a trusted Toyota-specific shop for maybe a few hundred more) do the work, you'd get the side benefit of walking away knowing a professional that's probably done it before finished up the work, and you've got some recourse if anything is effed up.

    Plan for three days, take a day and a half maybe two full days. I hadn't done a TB before, but it took me the better part of a day and a half taking my time and replacing other stuff in there.

    Bag and label all the parts you take off and keep a clean work space. Yes, move the engine accessories out of the way (AC compressor, PS pump, alternator) and take the radiator out too. Buy or rent the tool to get the crank bolt out that holds the crank. Rent a harmonic balancer puller, yours might come off by hand.

    It seems daunting at first, but if you're semi-handy with tools you can DIY. Just do plenty of research before hand and watch the videos linked above repeatedly.

    Here is a video by a Toyota mechanic doing a timing belt change on a 2006 Tundra 4.7......

    By far, the best video I have seen on replacement of timing belt.......

    Trust us.....use the "T" mark for putting belt on.....camshafts will not unload & shift on you.....

    I believe this guy has a very useful hint for getting belt on without frustration.......watch carefully 4:20 to 5:20 mark in video......turn off music in video...very irritating....

    we are also here to help you......a lot of us have been down this road many times and are very familiar with the timing belt process.

    Here's the post I started a bit ago. Like you said, it didn't end up going anywhere. I just updated the initial post to include the two videos posted here.

    I just did mine over the weekend. I spent about 9 hours working time between Friday and Saturday. Biggest pains were the oem radiator hose clamps and the rear bolt on the AC compressor. Not a terrible job just lots of steps and time consuming.
