    hey all,

    so my recently purchased '95 v6 tacoma is pretty high mileage. how do i know if its timing belt is near EOL? or for that matter, the water pump? should i just drop the $250 and replace both right now, or are there warning signs before a failure? (from what i understand a visual inspection of both is the same work as an actual replacement, right?)

    thanks,
    derek

    Without doccumentation, Your not gonna know. You cant tell if it needs to be replaced by looking, and there is NO warning before it lets go. Better off gettting it replaced.

    If you found someone to replace the belt and pump for $250, then that's an absolute screamin' deal. I replaced the timing belt on my Brother's Avalon with a V6 engine and it was a royal nightmare. Like Chris said, belts snap without any warning. If you do it yourself, it will probably take a good weekend. Personally if I had it to do again, I'd have a shop do it.

    bummer. but good to know, thanks. :)

    yeah, i was talking about replacing it myself. one of the how to write-ups i found said belts, water pump, timing belt all together should be $200-250 in parts. looks like a *long* weekend project.

    Where's the belt located on the Taco V6 engines? The front?

    That would make it a hell of a lot easier. On my brother's it was on the side and you have to remove the upper engine support rods to get at it. That and its a lot harder to get at from the side.

    If you do wind up replacing the belt and pump yourself, the most difficult part is going to be removing the crank pulley. Its held on with a huge amount of torque. I had to make a sort of tool to hold the pulley then loosen it with a 3 foot long breaker bar. Probably not a bad idea to have a torque wrench either because you'll want to make sure the torque is correct when you put everything back together, especially the crank pulley.

    i saw the homemade version of the special tool. i think i can make my own version. have a torque wrench too, mostly for the axle nuts on my bike. but this will definitely be the largest vehicle maintenance/repair job i've ever tackled.

    I made mine out of a piece of 1" square tubing with two pieces of steel welded on the top to form a "Y". I drilled two holes, one on each arm of the "Y" to fit the holes in the crank pulley. Then I just screwed the bolts through the tool into the pulley and tied the tool handle to the frame then just used the breaker bar to get it loose. I thought about trying a method that involves tying the breaker bar to the frame and bumping the starter. But I could just see the breaker bar flying off and causing damage or something. I'll try and get a pic of the tool. I think it'll work on my Taco too because it looks like the pulley is the same size.

    I just looked at the link posted by Janster. Looks like this engine has the same tensioner as the one on my Brother's car. These use 250 pounds of pressure to hold the belt tight. We had one hell of a time getting it back on there, and there was 2 of us. If you have a large vise, you can slowly compress the tensioner to a point where you can stick a pin through a hole in the side which will hold the tension in place until you install it. Then pull the pin. We didn't have a big enough vise so we had to muscle it in there.

    In regards to the belt, there are usually 3 marks on it. Two that are dotted and one that is solid. The dotted lines match with the timing marks on the cam sprockets. The solid is for the crank sprocket timing mark. These marks should line up with these perfectly. Otherwise if you don't the sprockets will move off time when you apply tension. The belt goes on one way, so if you put it on and the timing marks don't line up with the belt markings, then flip it around and put it on the other way.

    Anyhow, if you don't have a shop manual for it, I'd get one and follow the replacement instructions step by step. Good luck!

    If it has one, I would consider replacing the fan pulley idler bracket while your in there. I have changed a couple of these after the bearings froze up. The tear down is almost as much as a timing belt. I say if because the two I've done were on 3.0 4runners and I'm not as fimiliar with older Tacoma's. I believe the 3.4's have them as well.

    Timing belt replacement at 190,000 miles, no special tools, 2.5 hours. 2001 Tacoma 3.4L.

    I could do these all day long. I actually enjoy that job!

    If you have the ability to think things out with common sense, its a piece of cake!!!

    Be sure to grease the fan bracket while you have it off. Look up "Fan Bracket Free Fix" must read.
    It will save you lots of cash....

    My original fan bracket has 210,000 miles on it so far!

    Compress tensioner with large "C" clamp, carefully, large means 8-10" clamp
