Hello, I'm new to this site and have been reading your posts for a while. The car I have isn't a Daewoo, but I think the motor is, except there are some differences that I've noted, in particular about the location of the power steering pump. On this car, a 2004 Chevy Aveo, the pump is outside the timing belt area. On the schematics that I've seen on this site, it shows a picture of the pump being within the belt area. In this area, the motor mount is there.
Anyway, I have a question about the timing on this motor, as I've went ahead and changed the belt. Is anyone here familiar with this motor (4 cylinder 1.6 liter)? If so, I'll come back with my question. I'm really not even sure if I'm on the right site, but I can't really find anything else out there in the form of a forum that deals with this particular car. Or is this just another model of the same engine? I'm not sure. Please let me know if I'm on the right track. Thank you, Aveo Owner.
Mainly a test and a question.

Well I had a reply written up but I got logged out before I could post it. I'll keep it short I guess. Yes its the second schematic that you have shown, Daniel.
Long story short, I did the timing belt change and now the idling is a little jumpy and rough. Once it revs up it runs just like it always did. I did it the way it said in the Alldata site with making the 2 revolutions and tensioning the belt. I did move the crank pulley around a bit but, I don't think I have it off more than 1 turn. Could it be off 1 tooth? I hope not, it took me about a whole day to do this project and its starting to get cold up here in Maine and I don't have a heated garage. I went ahead and changed the water pump but I didn't do the tensioner and idler pulleys because I didn't realize it was recommended until I was most of the way done and didn't want to wait for the parts to be ordered and come in.
I know this is an interference motor so I needed to get it done because it had over 67K miles on it and I wasn't sure if it had ever been done or not.
So do you guys think I did something wrong or will the computer compensate for a timing error or could it be something else?

it almost sounds like you might have gotten one of the cams 1 tooth off, it is VERY easy to do that. unfortunatly the ecu cannot correct a thing like this, the only fix is to take it apart and realign the cams again. but when/if you do that put the new tensioner and idler on too. glad to hear that people are taking care of their cars even with out being badgered about it. with only 67k miles on it, your car should last you at least 150k more with proper care!

Thanks for confirming my suspicions. I had a feeling I might have been off somewhere. Do you think it would do any harm to the engine to let it go until next Spring after the weather warms up again? It runs good and the Wife is off my butt about getting the timing belt changed out, and I can go deer hunting with a clear consious.
Well I try to keep my vehicles up. I find it pays in the long run and besides, I can't afford to let this stuff go. I've heard that a repair on this engine will run into the thousands if the timing belt breaks and it is running. If I had to go to a dealer with every little thing, I'd be in the poorhouse for sure. That's why I appreciate sites like this one here.

you might experiance lower gas mileage, and possably fouled spark plugs. imo, order the parts you need, now that you have done the belt once, it will be ALOT easier, you should be able to do it in (just a guess) about an hour. i say if you can, do it soon.

That's normal

Re: Mainly a test and a question.
Hey, just wanted to post back and let everyone here that tried to help me out that I finally did get the timing changed and I evidently got it right this time because it cleared all the codes that were set. By the way there were 4 of them. I guess the timing being off can create many problems. I even had one related to the transmission.Don't recall what it was though.
When I set it this time I had my son hold the camshaft gear in the proper position while I slide the timing belt on the the pulleys. Last time the left side one kept trying to pop down off from a lobe and it made the belt be off by one tooth. I just figured that's where it's supposed to be........WRONG!!!!! Oh well, live and learn I guess. It's one for the books I guess.
And I also did this in under 3 hours, getting a little better hopefully. I don't think NASCAR is in my future though. LOL.
All the best, Aveo Owner.

Re: Mainly a test and a question.
Hi all-thankfully I have found this site and I believe what you all have said has confirmed my suspicions, but I want to be sure. I own a 2005 Chevy Aveo Special Value Model, 1.6L 4cyl. Yesterday I replaced the water pump, automatic tensioner, timing belt, and serpentine belt as preventive maintenance.
I have some idling issues that I believe is caused by being off on my timing b/c of potentially incorrectly aligning the camshaft gears when replacing my timing belt.
Similarly to you, Aveo Owner, when trying to align the camshaft gears, I guess the camshaft was sitting on a lobe and as a result the camshaft gear (I believe it was the left camshaft gear) would not stay aligned where it should be (with the timing mark as close to the other camshaft gear's timing mark)--which as a result left me, like you, thinking it needed to be there. So I believe I aligned it incorrectly (see picture for how I aligned them).
When I first started my car after all the work, it started a bit rough and idled a little rough as well. No power issues while driving though. I think it may chug and hesitate a little bit, as if I may have seated my sparkplug wires incorrectly or something...or I could have just been driving in 3rd at too low RPMs and should have downshifted. Anyway, after driving it again today it still idled rough, and would sporadically drop RPMs. I don't know if it's misfiring or what. It completely died right after starting once, too, b/c the RPMs dropped so much--and threatened to a couple other times while coasting in neutral, at idle. Otherwise it drives fine though. No check engine light--but I've only driven it a handful of times since the work.
My questions:
Is my idling/dying problem definitely a timing thing, or did I seat the sparkplug cables incorrectly when putting them back on, or maybe something else? Also, is it okay to drive with it like it is right now, or should I fix this immediately? I don't want to bust a valve, but I just don't know if my timing is off enough for that to happen. And if I haven't busted a valve yet, is there still the possibility of that happening (b/c I thought if that were to happen, it would happen right at start up)? Thanks in advance for the help.

Re: Mainly a test and a question.
Marksta,
The timing marks on your 1.6 DOHC must go through a line connecting the centers of the camshaft pulleys screws while crankshaft gear mark is at 6.
You can hold camgears in place by clamping two wrenches like on the pic.
Fix that now.

Re: Mainly a test and a question.
Daniel-thanks for the reply.
So my idling/dying problem is definitely a timing issue and not spark-plug related? Is it still possible to bust a valve or would that have happened immediately upon the first start up? (Do I have anything to worry about driving it a mile or so to where I'll be working on it?)
