2004 Sequoia. In the middle of a timing belt, so far pretty easy. But.... I'm getting conflicting info on reinstalling the belt.
- Should the crank be set to TDC, or 50掳ATDC upon reinstall?
Going to grab some coolant and hoping for an answer by my return!! 馃榿

Some existing threads should answer your question.

Thanks, but not exactly. I should have posted pics before running to the store.
Basically each cam sprocket lines up with the lines to the left of the T. The crank gear hasn't moved since I removed the belt at 0掳 TDC. New belt in on and alignment marks lining up correctly.
My concern is if I need to turn the crank gear to 50掳 ATDC and then install the timing belt? Or does it matter if the Mark's all line up on the belt, cam sprockets and crank gear??

As long as everything lines up, you鈥檙e fine. I think turning it a bit can allow for a more stable position so the cams don鈥檛 want to turn under spring tension.

Ah, ok then. Still though, you can usually get more hits on an existing thread rather than on a new one so it might not be a bad idea to ask your question in one of those other ones. Either way your way deeper into that motor than i might try to be so good luck with it.

There is a mark on the bottom T-belt pulley that will line up with a mark on the new timing belt. You see it from the bottom. Check out A-1 Autos You Tube videos (3 parts), very informative and concise. As advised, check other posts on this site... Chap

I got it. I looked through other posts, have yet to find the answer. I got everything lined up properly, but one video and the instructions that came with the Aisin kit said to turn the crank 50掳. In the one video the guy also had to turn the cam pulleys to make all the marks line up, so I don't really understand what was gained.

There are different instructions for different year models. Follow whatever is in the Aisin kit instructions for your year model. I don't recall what it is or I'd tell you. All I remember is that i read a bunch of crap online about putting it at 50 ATDC and my cams would roll over if i put them there. Mine is an 02 and that isn't what the Aisin kit instructions say. So just read the directions that came in the kit. The A1 video is for a particular year model and they don't tell you that the it varies by year model if I recall. The A1 video is good about telling you how to get everything apart. But to set the timing, you need to follow your kit directions.
