    I'm hearing some noise that sounds like ticking, it is independent of vehicle speed but directly affected by engine speed, so I think it is coming from a belt. It is loud enough to hear from the drivers seat while idling at a light and it is near the front of the engine bay too. I don't have an expert ear for this kind of stuff and it is hard to locate but I saw a thread for a different model year that mentioned timing belts should be replaced about 90k, does this apply to my 2000 Tacoma? Could this be making that noise?

    I have not replaced any belts at all during the time I have owned the truck. I bought it about four years ago at 70k, it is now at 135k.

    If I take it to a mechanic what would they check, and are those things I can check myself?

    Timing belt will not cause a tick....
    The timing belt can snap at anytime without warning

    With 135k miles - you're on BORROWED TIME. Get the timing belt, water pump, and thermostat changed.

    Yikes. Any other opinions on this?

    Which of those can I do myself?

    Okay, I'd classify myself as a shade-tree mechanic that has no problem with oil filters but I've never gotten deeper than the spark plugs on my truck. I saw another thread saying it would take a dealer 4 hours to do these things, that probably equates to an entire weekend for me and a lot of mistakes and redoing things... Hmmmm

    Looks like a 4-cyl. Don't know about that yr., but on the older 4 cyl's there is a timing chain, with a chain tensioner and 2 chain guides. If one of the guides breaks it will cause that type of noise.
    I had that happen on two motors, with about the same milage.

    If it has a belt, it may be as simple as a valve being out of adjustment.

    The guides are only plastic so they wear out as the above said

    Just spoke with a mechanic who was recommended by a friend. He will be investigating the noise starting with new belts.

    How much should I expect it to cost for him to change the water pump and thermostat too?

    Well you have a timing chain not a timing belt but anyways, the water pump and thermostat shouldnt be too much more at all because those two parts are very easy to access once you have everything else removed for the timing chain job. The kit for your truck is around 220 bucks not including the thermostat, but the thermostat isnt much at all.

    At this rate we are talking about the other belts and not the timing chain any more. I want to start with the easy stuff. Also I read up on the water pump & thermostat replacement discussion. Lots of different opinions. Ultimately I'm not going to do anything right now unless absolutely necessary.

    My 2.7 has a tick. It only ticks when I let off the gas or the engine is idling. It only seems to do it when it's cold out. Never caused an issue.

    Have him check your valves may just need to be adjusted. Mine had a tick, was out of spec, small adj and good to go

    I would check under the hood to see if there is a sticker with a date or near the timing belt housing and last but not least, near the radiator shroud.. I have an 03 4x4 DC with about 115k and I'm getting the timing belt water pump thermostat all done next month.. Good luck!

    As others have said, and I have since verified, I have a timing chain. I have read both sides of the debate about replacing the water pump and at this time I will not be replacing it unless the mechanic recommends otherwise. I am willing to take a risk and wait until it shows some signs of wear before replacing it. I pay AAA and they will tow me 200 miles if something fails.

    The mechanic found nothing wrong and said the engine is just getting a little "noisy" in its old age. Belts looked fine too.
