Failing at timing belt installation. 2005 aveo 1.6L

Yeah I just pushed through the resistance. It was harder in spots, like it got easy around 12:00 and the hard again
So I loosened water pump, adjusted tensioner to the left mark. Tightened water pump back up again.
Cranked it 2x again, was still resistant in the same spots, but easier overall

Started the car to be sure, before I put it all back together.
The car started and ran, but all the tension came off the belt. The belt was about to jump off the pulleys.

?????
...I've been driving it fine before this. I don't think the tensioner is bad
It's fighting me every step of the way. Haha wtffff

If the belt came off any pulley, you probably toasted the head, and bent valves...
(That’s why I mentioned to put it all back together first). I’m assuming that when you rotated the crank by hand twice, there was no slop on the belt anywhere.
I’m thinking it was ok until you started it without all the covers on, and bad things happened.
Try putting it all back Together and hope for the best.
Let us s know....and good luck.

BTW the resistance you felt was valve spring load at certain points of the rotation.

Yeah I rotated it twice when the pointer on tensioner was at the notch. And then twice again when the pointers lined up with eachother. Both by hand. All good each time, lined back up.

It never came all the way off the pulleys. It was hanging like halfway off. I guess there was still enough tension to keep the timing cuz it all like bed up again when I got crank at TDC...?
I tried it again but put the the outer pulley over the crank sprocket. The one for the serpentine belt. I was thinking maybe that might keep it from walking off somehow. But that wouldn't explain how I lost tension ..so I just threw a new tensioner on. Idk.
I started it up again for a sec. Didn't lose any tension and it didn't walk off. All the valves were tapping pretty loud, and fast. I heard that's normal and will go away??

*yeah no slop by hand
Putting it back together. I'll let y'all know..

[Carlodi4]

* I wouldnt know that it was valves I guess, just coming from that area

[Carlodi4]

Yes I see, you said go left..I went right. Dammit

[Eg.h2o]

Hopefully it’s all good now!

[Carlodi4]

Yeah. I feel like I leveled up. Thx for the help

Personally I don’t do marks on the belt. They won’t line up after turning the crank. The only things you have to pay attention to are the markings on the cams and crank. After two (or four, or six..) revolutions those should line up again.

yeah, the cams like to spring back....

just don't use the starter to spin it over. Do it by hand, and then put everything back together before using the starter. Bad things can happen otherwise.

I've never heard of marking the belt. My trick for this is to line up all the marks and find a pin that you can slide into the teeth between the cam sprockets. Doesn't have to be tight, just has to jam the cams. I think I used to use a 3/8" ratchet extension, it had the extra advantage of being too long to forget it in there when I was done. Of course it's easiest to do it before the old belt comes off but it could work for you even now.

just chekn n, you made newsletter, get ur timing belt issues solved? mark on crank 6:00, cams 3&9 o'clok basically one tooth below one tooth above, or just enough to be NOT even, if your getting one at 11:00 thats way to far off, 3 & 9 i got my cam tool from amazon..BETOOLL HW8014 CAM LOCKING TOOL mine is '09 so i 'm not sure it will fit, has rear gear lock if sprocket locks dont work, crank/flywheel lock, set gears to marks forget belt marks, belt will be very tight on right going to cam, left side has tensioner/water pump rotation to set tension, i think, '09 has serpentine belt , sounds like ur on right track, cept counting belt teeth is where your going wrong. mark cam pulleys 3 & 9 and dont let move from there more than half tooth, good luck everyone has first. it was my first twin cam, kicked my azz, three days trying to figure how locking worked, then BOOM IT JUST DID, gears off just tooth from eachother belt was tighter than, ah, u no, gotta do it again in 60k miles
