3.4L Timing belt replacement

I'm sure there has to be a link around here somewhere. Any recommended videos on replacing the timing belt on 3.4L 1st gen Tundra?

Thanks,

Try that google thing...

 

I know this is a long time coming, but thought I'd just follow up. This is as much for my own edification as it is for anyone who comes across this thread.

I ended up going with the Timmy the Toolman tutorial (https://www.youtube.com/watch?v=vHC46ypHxWc&t=6247s). It's a bit lengthy, but he really gets into it. He has a part 2 addition to the the video that explains how you should bolt on the tension pulley by a handful of threads and then tighten it after the belt is on.

But he did miss one thing I think was critical, he didn't go over making sure where the belt needed to be set up on the crankshaft gear. The line on the belt needed to be lined up with the dot on the face of the gear. The first pic shows this. I added a little piece of tape to make it easier to see.

I would also highly recommend getting the harmonic balancer wrench he uses. It's easy enough to use the engine starter to break loose the bolt. But when putting it back on and getting something like 270 ft/lbs of torque, it requires the specialty tool. I ended up wrenching it as best I could by putting the truck in gear with the e-brake on, but still didn't reach the recommended torque. I'm likely pretty close, since I've been driving for a while now with no problems.

Another thing is that I had ordered the Aisin timing belt kit from RockAuto. But after reading some of the posts here that you should only use OEM Toyota belts, I went to the dealer and got a belt. Upon inspection of what was on the truck for the last 100K miles, it was an Aisin belt and water pump. Neither of which had any noticeable imperfections. That being said, I went ahead and just used the Toyota belt anyhow, but I don't see any reason to not use Aisin products.

The other thing is to make sure to close off the holes in the front cross member. I learned that the hard way. Thank goodness for the magnet grabber!

 

I wish you luck guessing with that 270 ft lbs.

 

I haven't performed the job myself, but the Timmy the Toolman videos are very thorough and informative.

 

Some misinformation from time to time on the videos, but that's the case with a lot on YouTube these days. Hell, nobody is perfect, even I get it wrong often enough, but I'm quick to correct when/where I realize I did, and give props to the person who pointed it out.

I'd heard about his temperament from others in the Toyota community, how he blackholes/bans/berates people who point out mistakes in his content rather than edit to fix the issue/confusion. Didn't fully believe it was the case, then he came on here spamming video links, and starting crap with forum members here (me included, though I wasn't looking for beef). I learned after the fact, dude has apparently pissed a ton of people off with his attitude/behavior.

There are a couple of other channels that are typically error-free but high-quality content which I'd plug to add to your linklist, potentially as alternatives:

• https://www.youtube.com/@ToyotaMaintenance
  
• https://www.youtube.com/@TheCarCareNut
  
• https://www.youtube.com/@FayeHadley

YMMV.
