Hi Folks, coming up on the 2nd timing belt service on my 2001 V8 Tundra. I had the Dealer do it last time and he just did the belt and waterpump. I've done a couple of Subaru timing belts and I thought I would give the Tundra a try. I've watch a ton of videos and read a lot of info on these forums but I have a couple of questions. Where do I set the timing marks before belt removal? Seems that some use TDC and the slash marks on the cams and some advance and use the T mark on the cams. Anyone know which to use so the cams don't jump on me? Also is the Aisin TKT-021 kit the go to kit? What about the AC compressor, does it have to be removed or just the 2 front bolts to get to that bracket? Thanks

Watch both Otramm (2 part) and A1 Auto (3 Series) Videos. Just watch and listen and take notes. Suggest replacing your Radiator, all Coolant Hoses, Alternator, and Fan Clutch whilst ‘in there’ just because its all open and only a little extra $ and time in the big picture compared to doing it again. We call it Preventative Maintenance.

Don't forget that serpentine belt... Chap

Thanks for the suggestions guys. I've watched the A1 series a bunch of times and the part where he installs the belt is still confusing, seems like his timing marks are all over the place

On my 2, I have set them at tdc and the cams don’t move. I still have both boxes from the aisin kits that I used with their specific instructions. I could take photos of them but I believe they’re both in storage at this point. It’s not a hard job. Really an easy one for a timing belt. Yeah there’s quite a bit to take off, but do it all in order, take your time and it’ll all go back how you took it off.

Thanks 01tundraDC, from what I've read you use TDC for 2004 and older and the T mark for newer. I'm gathering parts now and I'll report back after the job.

Just did mine ('00 Tundra 1st Gen), timing belt broke on previous owner so he dumped it, I snagged it, got lucky, no damage to valves. I followed the A1 3-part video to the letter, worked like a charm.

To the question of timing marks: I had the same question/issue. Yes use TDC. Remember that the notches on the CAMs are the timing marks and when you try to put the belt on it will line up perfectly (if you put the belt on correctly, remember RIGHT side is PASSENGER).

Also, instead of sourcing parts I just got this kit from ProPartsUSA. It has everything you need:

Timing Belt Kit Toyota Tundra 4.7L V8 (2000 2001 2002 2003 2004 2005 2006)

Timing Belt Kit Toyota Tundra 2000-2006 V8 (4.7L).

Thanks otown for confirming the timing marks. As soon as it warms up a bit here in Oregon I'm going to dive into the job.

Has anyone here also replaced the Cam Seals?
That seems to really complicate the job, but of course is most thorough to perform.
Am thinking to change just belt, pulleys, tensioner and WP at/by 105K(103.5 now) and save the seals for next time on my 2006. Unless of course I find seepage.
On second belt change will also install new fan bracket/clutch then.
Thoughts?

For my 2002 non-vvti V8 the Cam Seals and Crank Seal was easy work. Plug and Play.

The vvti engine is much harder from what I understand because the Cams need to be removed?

Just finished my timing belt kit install. Took about 12hrs over 2 days but I'm sure I could do it in about 8 next time. I followed a guy on you tube named Otramm, its a 3 part series. The only goof I had was the very last step when I was tightening down the neg battery cable the bolt snapped on me. Oh well

 

[Chappy R]

Good news. I enjoyed changing that timing belt, etc. in mine. Only oops was a battery bolt, Praise God! Glad you "enjoyed the adventure..." Chap
