I've watched dozens of videos to understand this process. YOU ARE THE ONLY ONE who has been able to teach this effectively without any all the extra bs. To the point, precise and consise. You're a GREAT EDUCATOR. Thank you for your time and expertise.
Wow, awesome video. I can tell that you are having a hard time reading from your script/screen/teleprompter. Nice, clear voice. If you need to wear glasses, that's cool. Nobody will think you look dum. If they do, then their dum. Nice job.
Very clear lesson in changing the timing chain on these engines, with these instructions everybody with basic mechanic knowledge and tools can do a proper job 👍.
you put the VVT solenoids in the wrong position, Grey INT VVT solenoid goes on the intake side, Black EX VVT solenoid goes on the exhaust side. Great video though
@@Brouse I use "white out" on all the timing gear parts. Mark them at the gear tip. Makes alignment super simple and easy to verify I got it right or wrong. Super helpful on the rear cam for exhaust, as it is difficult to see. 🕵️ 😎👍
Very informative I got one confused statement there that I'm not quite digesting, you said activate the timing chain activator then you said after activation it will be very difficult I'm confused what does that mean then you showed a basically screw it into it engages with the unit that puts the pressure on the camshaft timing chain like normal timing chains does I'm confused look like a basic elementary procedure to me
Did you figure it out? I see this outfit doesn't want to answer questions. Dummy me took the sprockets off without looking where they were. Now I need to know where the cams need to be because of the cam sprockets off. I know the crank is at 12 o'clock to be top center. I need to figure where the cams go to know intake and exhaust are right. I can put the sprockets in the key way on the cam but it could be one turn wrong. I'm scared to continue without knowing for sure. I see I can't ask this dude because they don't reply.
@@dano9973 a good point of reference is to count the chain links. Use this video or similar to count the links and the distance between the marks on the chain. You can also look online for the chain and count the mark distance there too. if I am correct, the distance between the exhaust and intake camshafts have 14 links inbetween. This is a good starting point. Also count the amount of links on your chain and compare it to the ones you see online. Lastly, count the diffrence between the exhaust cam mark to the crank mark, and and the intake cam mark to the crank mark.
He tells you the position at about 2:25 in the video. Just make sure you're not turning the engine too much. You have to worry about interference with the valves and breaking the valves so don't force the engine when you're turning it. You need to look at the position of the cams and the valves to make sure you're not going to hit anything. If your chains were broken, there's a pretty good chance your valves are piston are already busted up. I converted the end of an old compression tester so I could actually blow compressed air into the cylinder with the valves closed and see if it held air or whether you could hear it leaking through the engine. Just don't use too much air pressure as it will actually turn the engine and you might cause damage that wasn't there to begin with.
Put a piece of paper in the camber and if it pops out you’re on the compression stroke. Spin the crank one more revolution to get to the desired stroke. But make sure it’s on the compression stroke. I’m not sure why this guy said to be on the exhaust stroke
There is nothing definitive I've seen. On the non DI Ecotec engines I've read that the nylon guides break down with age not so much mileage. This happens around 12-15 years. Again just what I've read. I've got a 2008 Solstice so mine will probably need to be replaced soon even though the engine only has 29K miles. But who really knows. Supposedly there will be a loud rattle on startup when the chain needs replacing. You can also pull the VVT solenods and look for metal shavings on them.
Timing components hardly ever need to be serviced. However, they do if the engine is not maintained well, then you start to have issues such as, chains stretching, tensioners failing, guides wearing out, etc
I'm actually doing this job right now and if you're careful and shine a light, you can just barely see the tip. I also used a little inspection cam to double check.
Pretty sure you just remove from the back with a 32mm socket. Put the new one in at 55 ft'lbs, then activate the tensioner by pressing the guide into the tensioner. They are activated by puhshing them in about a 1/8-1/4 inch. You will need you remove the valve cover to depress the tensioner
@@1111comment you just replaced the tensioner? no chains? I got my cover off and nothing is broke and i'm considering that especially since it appears in time still
Is there a way to adjust the timing without marks? I took the chain out and my stupidity allowed me to turn the the sprocket s individually, which turned the cams. Now I have no idea where I am at. Call me an idiot because I am. 2015 Chev malibu 2.5
Turn the crank a quarter turn bringing all pistons to the center of the cylinder. Rotate the cams to their proper positions using the timing marks. Bring #1 back to the top.
Why at 6.28 are you calling the left side the intake balance shaft and the right side the exhaust. That's true if your using rear wheel drive vehicle definition. But on the stand as presented it's opposite
There was a difference Chloys did not activate the camshaft activator before they put it in they screwed in and then run a long ride down in their to activate it that was what was puzzling me. Like the way he did it that's the way I'm accustomed
You are wrong in parts of your video. The 2.0 takes a different lower pully than the one shown for the balance shaft. 2nd the Exhaust balance shaft is on the Left side of the engine when facing it. On the 2.0L Turbo engine.

absolutely the best info video out there. thank you
Doing this job (plus the water pump) tomorrow. Thank you for the awesome video 😎👍
Doing it currently, and not having fun lol

This is a great video! I wish that I could work on my engine on a stand instead of in the car.
Love the video but could have been even kinder to include torque specs of the balance shaft sprockets

Thank you sir
It is worth upgrading only the revised tensioner on an ecotec that no issues? 2013 2.4L
Was this the tutorial for the 2011 ecotec 2.4 LAF engine, Because there are different ways to set the timing on these?
Can u turn the sprockets separately to line them up if the crank is already in the right spot
What engine flush product do you recommend?
Can you get balancer gears for a 3.5L ?
Wait...isn't the tensioner supposed to be activated AFTER install?
How do you determine if the #1 piston is at TDC of the proper stroke if chains were broken?

How do you purchase the kit?
How would you know when to replace the timing components? The maintenance schedule does not include anything on the timing system

You have to be top dead center on the compression stroke why the exhaust?
The timing on this motor is set on TDC of the exhaust stroke, not compression. Don't know why.
Has you all forgot engine view is from the driver seat?
I see your engine's all cut out to see the tensioner pin hitting the guide, but I don't see how you're supposed to see it on a normal engine.
I'm actually doing this job right now and if you're careful and shine a light, you can just barely see the tip. I also used a little inspection cam to double check.
12:13 activation. Any tips on replacing just the tensioner?
Pretty sure you just remove from the back with a 32mm socket. Put the new one in at 55 ft'lbs, then activate the tensioner by pressing the guide into the tensioner. They are activated by puhshing them in about a 1/8-1/4 inch. You will need you remove the valve cover to depress the tensioner
@@etchris I also used locking pliers on each cam shaft.
Fixed P0016/P0017!
@@1111comment am doing a timing chain replacement this weekend, doesn't look to bad! Hopefully all goes well
@@etchris good luck man. yeah doesnt look too bad. worst part on mine is dropping the engine an inch bc of one bolt; can't make it too easy. 😂.

Bro same thing happen to me, did you figure it out?? I'm stuck
Turn the crank a quarter turn bringing all pistons to the center of the cylinder. Rotate the cams to their proper positions using the timing marks. Bring #1 back to the top.
Nothing about how to activate the tensioner?
Why at 6.28 are you calling the left side the intake balance shaft and the right side the exhaust. That's true if your using rear wheel drive vehicle definition. But on the stand as presented it's opposite
The front of the engine is the the timing chain end of the engine, and is using that as reference.
You can't install the tensioner activated. You activate after installed.
I agree that step wasn’t real clear in the video.
He activated it first because he turned the balancer to release the chain slack to one side to allow for the tensioner to be installed activated
You guys totally ripped off cloyes installation video for the ecotec word for word
There was a difference Chloys did not activate the camshaft activator before they put it in they screwed in and then run a long ride down in their to activate it that was what was puzzling me. Like the way he did it that's the way I'm accustomed
You are wrong in parts of your video. The 2.0 takes a different lower pully than the one shown for the balance shaft. 2nd the Exhaust balance shaft is on the Left side of the engine when facing it. On the 2.0L Turbo engine.
You will be a millionaire selling those thx to the trash that GM produced those oil guzzling engines.
My 2.4 has 183,000 miles and gets 5000 miles to the quart. I use Mobil1.
Please...stop calling Ecotec .....echo-tek....it's not echo-tek....
