- The investigation of a "crank, but no start" symptom in a 2003 Chevy Cavalier with a 2.2L Ecotec engine begins in part one of this video series. View the introduction to the problem and what we found when the valve cover came off. The engine is rotated to the top dead center position as well. The Ecotec engine is found on many four cylinder GM cars worldwide, such as Cobalt, Cavalier, HHR, Malibu, Alero, Grand Am, Sunfire, Saturn L series as well as some Opel and Vauxhall cars and more.

I have an 04 Chevy Classic that uses the 2.2 Eco. I believe my chain broke going about 45mph down the road. Car immediately shut off and when it's attempting to start it sounds like metal hitting the cover where the chain is. I haven't touched it since it busted, I'm fearful of engine damage. Thank you for this video series, as I'm about to watch it and pray I don't have a toasted engine.
i had the same feeling doing this repair. All you do is put on new chain and guides and try to start it and see what happens.
This series on the 2.2 is great watched the entire series and learned enough to get me through the job. Thank you so much!
You're welcome. I'm glad it helped and I appreciate your feedback.
I NEVER LIKE AND SUBSCRIBE TO ANYONE but after ALL the detail I'm seeing you put in your videos I will definitely subscribe thanks for a great video
thanks for the info on this I watched all the parts and it helped I had to on mine which was a 04 cavalier , needed a head gasket , balance and timing chain new water pump it took some time but she finally started up today well I finished it today took about an hr ended up jumping it because the car had been sitting for 4 mnths had to wait for parts and money to get it but the battery was low so finally gave it a good jump and after 3 tries then it fired up runs great again thanks for the video it did help great info also this was my first time doing timing
You're welcome and great job!
Thank you for the great detail and time you put in on the s videos . They were a great help on my project.
You're welcome and I hope your project went well,
i guess I'm kinda randomly asking but do anyone know a good website to stream new series online ?
I just bought one of these.
All of the forms i read online warn me of the Timing Chain after 100k Miles. Mine has over 200k & it is still running.. But I do not dare to drive it very far until I get this chain looked at.
The cylinder measuring tool what's the measurement to make one?
Is there a difference between the 2004 Chevy cavalier 2.2 and a 2007 Chevy HHR 2.2? How can I find out if the engines are switchable
I am doing this job right now and using your videos as a guide. I do have 1 question non-related. Why is there 2 axle shaft nuts on the half shaft?
Nice video man good detail on what your doing just next time get a cheap go pro 50 bucks and one of those stands with the legs should come with it
1:46 we all say 8mm, but it’s actually a 5/16”. Why they used standard instead of metric, idk...
Hey, my car has had all the warning signs of the timing chain needing to be replaced. Popped the cover off to diagnose and the chain is clean and tight.... What else could it possibly be if the chain is perfect but the car sounds exactly like the car in your video?
The chain is tight, but is the timing correct? I would hand rotate the engine and check that. Make sure you are getting gas. The fuel pump failed on this same Cavalier a year earlier.
Hi David, great series of videos. I'm doing this same repair on an 03 Cavalier as well. I'm stuck at the crankshaft bolt removal. I don't want to remove it without ensuring I'm at TDC on cylinder 1 on the exhaust stroke. But, how do I verify that if the indicators on the timing sprockets have lost relationship with the cams?
I did try to show that in the video as the same thing happened to the one I worked on. I also have a video on identifying valve and cam positions on one cycle of that engine. I hope it helps. ua-cam.com/video/cfMfVi9nL_A/v-deo.html
Hi! Help! Mine too crank but no start. I change the tensionner without removing the valve cover and it skip one or 2 teeths before activating. Now, is it safe to turn the cam or crank in order to time it when installing a new kit? Can i turn the crankshaft colockwise and counter clockwise?
Just don't try to run the car and you should avoid risk of damage. Just turn it manually and always clockwise as this is the normal run direction.
will this be similar on the 2002 alero 2.2l same engine i think
I would think your engine would be very much the same.
Hi David, I just screwed up big time doing a water pump replacement. I didn’t use the tool correctly and the gear for the pump came loose on startup. The car ran perfectly fine before. Do you know of a fix for this that doesn’t involve pulling all of the timing components?
I didn't do the water pump (not a great idea). I'm thinking you're probably going to have to take it most of the way back down but I know how far. I've done stuff like this too and it totally sucks.
@@TheOriginalMechanic thanks for that David, it really shattered my pride when that happened. Makes you question a lot of things when something like that happens lol
is getting to tdc important here? and do I need to be on a compression stroke?
Yes you do need to be at TDC because that's where all the timing marks on the engine and chain line up. It is done on the exhaust stroke on cylinder one
@@TheOriginalMechanic Not sure if you'll see this question, but how would I find TDC on the exhaust stroke if the chain has jumped so the sprocket indicators no longer point to the correct positions?
Dave Smale TDC is dependent on piston position, which is a function of crankshaft position. You don’t use cam sprockets to find tdc. They only spin at 1/2 crank speed, and if the valve timing has jumped, the sprockets could be anywhere when the #1 piston is at TDC. This engine has a keyed crank pulley, so it can be used be lining up its mark with the mark on the timing chain cover. On a different engine, you may need a degree wheel or do some disassembly to get to a point you’re able to reference the cranks position vs the block.
Could use a steady camera hand from a second person otherwise very informative, I have a 05 but I also have white milky goo in the oil cap and condensation in the cap and breather and air filter compartment, Any Idea why that would be happening.
The milky white goo could be to coolant getting into the oil. On most engines this means a bad head gasket. If the engine is losing coolant a repair may be needed sooner than later.
I had same issue with my 2006 HHR. It was creamy looking gunck in my air intake duct, almost as thick as peanut butter. it was oil and water mixture, I took duct off and dumped a bit of water out. the water was from condensation build up from clogging. I removed intake manifold to clean the port thats inside. I also removed valve cover and cleaned the under side of it... problem solved!! for a girl I didn't do too bad :)
Honestly, I think I'd rather pay a shop to do this job on my '05 Pontiac Sunfire 2.2, how much do you think it would be? I was told by the 1 shop I checked with $900? What's your opinion? BTW I liked and subscribed, great details.
It is a big job. $900 seems like a good deal. I've seem estimates well over a $1000 for timing belt or chain replacement. Thanks for subscribing!
I was quoted 1800 to 2000. If I could have got it done for $900, I wouldn't done it myself. It's a job
is this the same for a 2005 chevy classic?
Can't say for sure, but if it's a 2.2L Ecotec it should be very similar.
Would this work on a 2004 Chevy Malibu classic?
Yeah should be the same motor, might have to move some stuff
@@CookedTickabc Thanks for the reply. Ended up just buying a new car three years ago.
What is the second chain in the engine by the timing chain for?
It runs the balance shaft and the water pump. Ideally that one should be changed when the timing chain is done.
It's a balance shaft!
@@TheOriginalMechanic I didn't know they should be changed together
I may have to do that soon!
How long did this take you?
I did this in cold weather and it took my time...about 5 days. If you go at it hard it could be done in a couple.
