    Right. I gave the impact a few taps on the switch and the bolt gave up it's grip. Then I laid on the impact for a few seconds to tighten it when it was time to put it together because I didn't have a torque wrench with that much range.

    Totally agree there is no need to take an easy risk. I told him he needs to get it done he just keeps saying he keeps forgetting.

    this is the one I use at work, don’t even need to remove the radiator. And unless someone previously overtightened the bolt, it rips it right off.

    I just got an 04 and had my mechanic change the belt and he said the water pump was leaking, so as it didn't get a lot of driving before I got it, I figured seals were old. The mileage was 120K.
    The 05 V8 is next. That has 13K on it, but again, not a lot of driving on it, so belt and pump for the seals. Figure the tensioners, etc. will be OK.

    The cam seals on the 05 are going to cost an arm and a leg if they need to be done just a warning. to replace cam seals on a vvti 4.7 you have to remove the valve covers and pull the cams

    It’s because of the vvti being added after the engine existed. Chances are yours are fine, but if not be ready. I did mine because they were leaking, but I also have 192k

    Yeah, did a check and vvti came into being in 05 and stuck on an engine already in production. Hopefully mine will be fine as I have better things to spend money on, like a topper, hunting and fishing gear, etc.

    I have never done a timing belt, nor the cam seals, before. I will possibly attempt these when the time comes in about 30k miles, or 3 years, which ever comes first. Assuming I still have the truck which most likely I will.

    The cam seals look like they should be done while the belt is off. Might as well do it all at the same time.

    When mine hit 90K I asked the lead mechanic at the Toyota Store where I did some other work whether he thought I should get the belt done at the time.
    His answer to me was that after the Apocalypse the only things he thought would be left intact were Cockroaches and the 4.7 liter timing belts.
    He said that as a Master Toyota Tech for 30 years that he had never seen one go bad or break and we talked about it a little and I have still not done mine yet.
    He of course did happily do them all the time and made the store lots of money in the process.

    Now I also bought a V8 4runner a few years ago that had just had the Timing belt done and the motor seized as the result of that.
    Again no mechanic who I talked to about it had ever seen that happen either but the moron who did the work evidently did not clean the whole belt path before putting it all back together and crap got in there and sort of derailed the belt for lack of a better way to describe it.

    So I am not saying which is right and if money were not an object to me I am sure I would just have the job done at 90K or whatever interval is suggested but I also take some comfort in the Toyota Mechanic saying I should really not worry about it too much.

    Better safe than sorry I am sure,if you can afford it at the time.

    I wrote an observation the other day, on another thread about the timing belts, in that I’ve never recalled seeing someone here on this site saying their timing belt broke from being old. Not saying it can’t happen. Plenty of threads complaining about their timing belts failing due to improper fresh installations or poor/off brand parts.

    Mine are leaking slightly at 169k. They will be replaced during the belt change out.

    Edit: I see I had a typo in my original quote that you quoted. I said ‘did’ where I should have said ‘will do’ water pump and cam seals. My leaking ones are the originals still.

    how many gallons of coolant did you need? do I order 3 or 4 bottles of 50/50?

    also did you replace cam seals? know a good link to buy them on Amazon?

    2-3 bottles of the 50/50 pink zerex should do the job. You can actually go to Walmart or their website and get the valvoline brand.

    I prefer to use the pre-mix due to eliminating dumb hand model mixing errors. Its so cheap just to buy Zerex Asian Pink. Think my local auto store was less than wallace wurrld when I did mine. $17isH a gallon IIRC. Need 3 gallons plus .1 gallon per spec. So, just buy 4 gallons and do a flush at your heater core (pro tip) which most overlook. That uses about 1/4 gallon.

    4 gallons of Zerex Pink will do you. Buy a new Denso radiator cap is another pro tip. $14ish on big gurrll.

    How much does shipping add? Good price on the gallon! Does shipping kill it?

    Local, online or wherever you can get it the cheapest. I also agree with just getting the 50/50 mix. It seems much easier that way.

    I do like rock auto but cost wise on liquid type products like this, local is probably a better bet. From also looking on the Tacoma boards and numerous post about it here, this Asian zerex pink mix is a very good substitute for the Toyota stuff. It meets all the requirements.

    Yeah. I checked for all the Toy and Japanese certs and the Zerex Asian meets them.

    If the cost saving was hugely, I’d do the concentrate. All those distilled plastík bottles and harming the nozone is a deal breaker. :D

    My 4Runner with the same 4.7L was done at 91,000 at the dealership, and cost was about $1000 (a decade ago). They showed me the belt and it looked pristine. But we changed it anyway. I'm now at 200k and will be doing it myself when the weather improves.

    Just bought a 2000 Tundra with 155k miles on the 4.7L. I don't know if it's ever been done, but will be tackling this repair myself too. I'm curious to see how it is. But it drives very strong.

    I need to replace the 4" tensioner pulley and also the idler pulley. But they replaced the 4" tensioner pulley with a 3.5" pulley. Problem is that the washer/cover and bolt do not come with the replacement pulley and those original parts won't fit the replacement. So now I'm thinking about just replacing the bearing for the 4" tensioner pulley and the idler pulley. Anyone know of a bearing part number that will work? 2004 Tundra 4.7L SR5

    I don't but I have found the Toyota service departments to be extremely helpful when ordering parts - they'll look up the parts and confirm wht you need. They have saved me from some costly wrong part install mistakes.
