30 year mechanic here. Great video. Thanks!

I have a 2.2 with close to 300k, Chain kit installed at 245k, still was original chain and tensioner. These are good little motors IF YOU TAKE CARE OF THEM!!!! so change that oil!!!

Dude this is super helpful and i wanna say thank you for the work you do

Great explanation sir thank you All the way from south africa 🇿🇦

Thanks for sharing. Yours is probably the most easily understood how to video. Great job!

I am become a big friend of your KZread channel ♥After watching only two Videos ♥ Take Love and respect from Bangladesh.

At 20:42 how did the phasers change position? Looks like each one was rotated 180 degrees when the transition occurred

Thank you so much ❤

Muito bom video gostei !

I have one of these engines to do chains on soon and my service data says I need the phaser locking tool that bolts down to the head and locates in the phasers? I noticed you didn't use anything to lock them, maybe it's not required?

I indeed have 3 cobalts and have owned at least 6 of these engines. I’ve done timing on one of them and can say if you follow this guys steps you will mess up as this motor is an interference engine… you should start on exhaust stroke as your timing marks should be in the 10 and 2 position before taking ANYTHING off. If you look closely at 20:42 you will notice the phasers has changed position by 180 degrees. If you’re new to cars or don’t have a ton of experience I would highly recommend taking it to a professional. Yes it is pricey but it’s cheaper than having to replace the whole motor…good look to anyone that try’s it. PLEASE USE A DIFFERENT VIDEO

Just wondering shouldn't the exhaust have the black link and intake have the orange link. Colored links on both sides of the chain? Maybe my ocd is just coming out.

I was thinking the same thing. I thought in the beginning in was reversed

Hey ive got a 16 equinox 2.4 auto awd. Its showing 3 codes i think, p219a, p0420, p0014, p0013 which is mostly timing stuff, fuel air mix, exhaust. it runs great one trip next time splutters everywere with lose of power until get plugs burning hot or something. Ive definatly gotta get a new hose that goes to use to be a pcv on Valve cover. But can you tell me what i need to do the timing completeley. lifetime warranty parts i dont like when their cheap because it means ill still have to do it again. If you have time id like to know what to buy and a fair brand something to actually last. Also my engine had the tube stopped offf on engine so lots seals and gaskets leak. What seals and gaskets that wont come in a kit can i replace while tearing into that part of the engine and any other things you would suggest changing instead of what i said? Any seals i can get to def needs done. it has abt 200000. people complains abt the 2.4 but ive not had to do anything until now with a lil over 200. ours has been great and we live in the WV mountians so its been used well. I hope you can find the time, Thanks !!!

Chad, I watch your video on the timing chain replacement, you were very good and precise. The only negative was when you torqued the cam shaft sprockets you said to torque to 22 ft pounds and another 100 as a diy I did not understand the 100. Would have been nice if you went through that torque process. Thanks for taking the time to make this video. Bill R

Think of a circle as 360 degrees. 90 degrees is 1/4. Look at the hands on the clock. At 12:00 the minute hand is straight up at the 12. If you move the hand 90° that puts it at number three. 100 degrees is going to be about give or take where the number 4 is. So when you tighten that bolt, you want to move that bolt about the same amount.

@@bigdnelyria Thank you for the explanation. I got it

My chain is so tight that I can't move it around the gears like you do I'm having you pay it all in line and try to tighten it up my cams was moved on me because I took the tensioner out too soon they may be may mess up how tell if cams are in right place

I have a g5 my engine whines like crazy but goes away when I turn 1 direction. Almost positive it’s timing guide. I wanna replace it all like in this videos but I’ll have to do it while it’s in the car. 2.2. I’m super sketched out.

When you set TDC in the beginning of the video you stated that the cam lobes should be facing up on the number one piston which is wrong. When you set TDC you have to make sure the cam gear diamonds should be facing at the and 2:00 on intake and 11:00 on the exhaust. I don’t know if you redid your TDC but when I saw you install the cam gears I noticed the cam lobes where facing down so idk what happened but people can be misguided if they follow those instructions.

If ypu notice in video his cam sprockets timing marks when at TDC on compression stroke are facing down and to inside, but video cuts then there in correct spot, this is due to 2.2 needing to be at TDC on exhaust stroke.

So you gotta pull out the motor to do it? I got the code says its bad.

So I did my wife’s 2012 terrain 2.4L.. how do I know if I have it at TDC on the exhaust stroke and not the compression stroke?

When the cams are in the right spot lobes will be as far away from the lifters as possible. That is TDS for cylinder one.

I was always told to get new sprockets with a new chain. Cuz the new chain will have slop on wore out sprockets. Cause problems.

The chain is what gets all the ware so many connections places, lay the new one on top of the old one check the size.

Since you had it apart, why didn't you replace the water pump and the chain? I mean it is already apart.

You could but that one doesn't have all the stress on it like the cam chain, water pump and balance shafts just spin freely so it should outlast the engine.

As a professional tech, you're 100% right. Both the timing and cam chains streach. Also the sprockets and chains should be replaced together.

Also, aren’t the camshaft-to-sprocket bolts “torque-to-yield” style? ( I.e. bolts should not be re-used? ) or am I mistaken? Please clarify this.

A good chain kit will have new bolts and sprockets, guide shoes etc, etc.

Great content , but probably shouldn’t have played with the timing like that. Would have been much better if u showed everyone how to keep everything under “Tdc” specs. Noobs/amateurs shouldn’t even think of advancing timing AT ALL. There are tricks to keep the cams from moving and ways to re install the sprockets without having to reposition the cams.

Cost for job installed

Is this the standard 2.4L, as found in late '90 early 2000 model Chevy, or is it the newer Ecotech version? Anyone know. Edit: for an extra $150 (Cdn) you could replace entire timing system; sprockets, chain, guides, tensioner. Even if chain is still "good" at 150k I'd still replace seeing as engine and cover already off.

Nobody should use this video especially if you are new to this. The timing was not set correctly before disassembly. Timing needs to be set at TDC on the EXHAUST stroke not the compression stroke as shown here.

Pretty sure exhaust should be at 10 o’clockintake should be at 2 o’clock there will be a triangle on the intake and exhaust camshaft sprocket and should be in forementioned positions. Crankshaft keyway should be at high noon. Anyway that’s what it is on a 2010 terrain 2.4 L. And camshafts both lobes should be pointing in words down. If I have done my work correctly. If I have not I will be more than happy to admit I was wrong. Before you put it all back together with the with the covers off Put the bolt in The crankshaft and rotate it clockwise slowly to make sure your valves aren’t hitting your pistons. If I have gave any miss information which I’m pretty sure I have not you will not feel any resistance as you’re rolling over and if you would like to be sure put a spark plug back in the number one hole loosely and you should be able to hear the compression release to the spark plug continue to turn not much until corresponding timing marks lineup again. If they do then you’re golden put it together and enjoy your engine you’ll be surprised how well it will run. Don’t forget to change the oilAnd filter. Do you need fresh oil and keep an eye on the level every week two weeks blah blah until you figure out in 30 days how much oil you need to add every so often do not let it run low you’ll end up with the same problem again. Have a wonderful day God bless

Do you have to remove the oil in order to change the chain?

Don't use a impact on those little bolts or you 'll be sorry. Use a ratchet and torque everything properly!

Why does the chain still have slack at the top when you were turning the motor by ratchet? -TIA.

Hello, I don't see in the video when and how the camshafts themselves are locked. The camshafts have to be locked before the camshaft gears are removed, or am I looking at this incorrectly? In every other engine, the camshafts are locked before the camshaft sprockets and chain are removed! Please to enlightenment.

Before you take the timing chain off you can take a 15/16 or I think it’s a 23 mm don’t quote me on that anyway put it on the nut just behind the camshaft saddle or where it bolts down closest to the VVT sprocket and the cam will I think it would be advance with the wrench lightly do not force it if it does move that is a bad VVT sprocket they’re not supposed to move they are supposed to remain locked unless there’s oil pressure. If they’re very loose you can hold that plastic piece on the end of the VVT sprocket and actually turn it by hand. I hope this helps

Soak the chain and components in oil so you don't start it up dry.

This job isnt so bad in the car the problem is the static guide blew off and it broke a bolt in their tapping it our is a nightmare

The gasket is NOT REUSABLE, for the LSJ AND LNF you wanna replace the gasket!

I think the instructions are incorrect for setting the timing

These videos give you at least a basic understanding of your car! Read the comments too! KNOW BEFORE YOU GO!
