    Newbie here,

    I have a 2001 Tacoma 2.7L V4 cylinder truck that just hit 100,000 miles.

    My question is what items are up for changeover?

    1) Timing belt?

    2) Water Pump?

    3) Tensioner?

    4) Other?

    Also I am in central connecticut. Any clue to what an approx cost would be to changeover timing belt & water pump & tensioner?

    I have tried to do some research which is conflicting that those three items should be changed all at once.

    I can not find an online a manual that would tell me all this so sorry for all the questions. :)

    Any feedback would be greatly appreciated!

    Thanks

    john

    The 2.7 is an L4, not a V4. It also does not have a timing belt, it has two timing chains. I wouldn't replace those at 100k, and unless you're doing it yourself you'd pay out the a$$ to get it replaced. A new water pump wouldn't be a bad idea, it's cheap insurance and you wouldn't have to worry about it later. And tensioner to what?

    Wow!,

    Thanks for the quick replies. I apologize my knowledge is weak basically because there is never anything wrong with the truck.

    The term tensioner was something I picked up in a forum while gooling timing belt change.

    My understanding then is my truck has two timing chains and this is something that I may never have to change unless it acts up. Correct?

    I will go with your advice and do the water pump.

    Is there anything else I may have missed? I am also going to change the transmission fluid which I was told does not take any special fluid.

    I appreciate the help!

    Damn, I wish I knew about places like this when I was replacing my air fuel sensor because a light went on. I went to a Toyota Service Center and paid almost $500 to do this!

    LONG LIVE TACOMA WORLD!

    Timing chain - you could say that.

    The 2.7 doesn't really have a tensioner like most you see. Or like most I've seen anyway. I don't really know how to explain it, although it may seem complicated it's not at all. If you look at the center of your motor, it should be to the right of the dipstick and to the left of the power steering pump. On the cylinder head there is a bracket with 3 screws? On that bracket there is a pulley type deal with a long screw that holds the pulley on the bracket. To take the belt off, you would first loosen the screw that threads INTO the pulley, then you would loosen the long screw that holds the pulley to the bracket. That takes the tension off the belt and then you're done.

    I didn't mean to make that so long, sorry. Hopefully that helps ya!

    At that mileage if it hasn't been done already I would suggest:

    Drain and fill on all fluids (transmission, differentials, coolant, transfer case if 4x4, and oil.)

    And then a water pump, valve adjust, spark plugs, upper and lower radiator hoses, grease drive shafts and ball joints and that should keep it going for a while.

    Guys,

    Thanks for the help and not being condenscending to an obvious amateur like myself. Just trying to take care of a truck that has been good to me and would like to get another century mark if possible while saving a couple bucks if I can!

    Mods,
    I dont know what you prefer....new threads or rectify old threads.

    Team Tacoma,

    I got asked if I should change my serpetine differential belt?

    They also showed me a long list of items I am due for.

    I am up to 120K. Its all highway.

    I do the routine air filter & oil change & tire/battery changes

    Thanks!

    Serpentine differential?

    No such thing.

    The serpentine belt is your fan belt, and yes, it should be changed.
    The belt tensioner might be going, but access is easy and if it's not making noise and the belt doesn't seem to be jumping when the engine is running, it's fine.

    Differential fluid should probably be changed.
