Replacing head gasket and timing chain set on 2011 Chevrolet Malibu 2.4L Ecotec engine. Should be the same setup used on multiple Gm vehicles equipped with the 2.4L engine.
This is very common, may even require cylinder head repair of the top intake chain guide bolt or head replace. There is also an upgraded access port plug that replaces the timing guide bolt. Bolt lossens itself and makes the threaded whole out of round and messes the threads up, causes loose chain and jumping of time.
good video.but i wouldnt use scotch pad on aluminum and use straight edge with feeler guage on 001 if it goes under ,machine it flush.and id check that head at machine shop for cracks and valves checked and put in a new water pump.with all that other work not much more to fix head and know and definetly water pump.well mabe the b12 pad may be ok but its trhe dust that can get into motor that can chew up cylinders or other stuff.but very informative and good job explaining and all round good job.
Great video brother... When you where cleaning the head i wish you showed the prosses for the top like you did the sides and bottom,,,my 2012 looks just as bad and it jumped time,,,
This is an excellent video.Thank you.i heard u should never loctite head bolts though.the degrees make the bolts super tight.also, the factory specs say the e12 bolts should be 26 ft lbs
You could grow crops in all the dirt you left in that valve cover channel prior to removing the coil packs. No bueno. After getting a bit further in to the vid...I don't think it matters lol.
@@ls1camaro92 quick question. I took off the top cover on my engine to expose the timing chain. I noticed that the chain marks were not aligned to the marks on the sprockets. Is this normal? Or was it not installed correctly? I had a guy change out my water pump and now I have a noise. He claims that one of my chain guides could be damaged which is causing a whining noise in my car when it's running. Any help u can provide is greatly appreciated. Thanks.
Wilson Aguirre Gomez well as long as the main sprockets face the correct direction with the marks, you should be fine. It will require multiple revolutions of the crankshaft turned until the chain realigns with the sprocket marks. And as for the water pump, if the water pump wasn’t installed correctly then very possible it can cause noises. But these guides can also become brittle and require changing. Usually the chain requires changed after 115k or if it starts making noises.
I have a 2012 Chevy malibu I need a new head gasket do I have take apart the timing chain n pully gears to take off the head in order to get to the gasket
Is it common for a bolt on the timing chain cover to be placed where it cannot be removed without dismounting the engine? I am considering replacing my own gaskets and timing chain. If I have to dismount the engine I will pass since I do not have all the proper mechanical equipment. Will I run into the same placement on my 2008 2.4L ? Thanks, and great video!
How did you remove the cam phaser bolts? I couldn’t fit my impact on the left one that’s towards the back cause the suspension port gets in the way, tried lifting the engine but still not enough room. Is it possible to remove them with a ratchet and socket?
How do you know to inspect the chain? Like does it run rough or not at all? My Chevy 2010 malibu quit on the freeway and a mechanic is telling me I need new engine. Edit: he did not remove anything just ran scan tool and turned the key and said he recognized the noise.
It looks like there’s a difference between exhaust manifolds between the G6 and Malibu. Unless this is an LE9 (E85 version of the LE5). On the G6, the exhaust manifold has the catalytic converter built into it. And the upstream O2 sensor is bolted horizontally, not vertically
Great video. I have a 2008 Saturn Vue with the 2.4 LE5. It has 86k miles and out of nowhere I get an engine overheating dash light. I pull over immediately and turn it off. Pop the hood, and theres no coolant in the reservoir. Shit...Check oil fill cap and theres yellow gunk on it. I see water droplets and oil pooled on the cam shaft. I drained the oil, it looks like caramel but it definitely wasn't overfilled an extra 9 quarts of coolant, but definite coolant in the crank case. I pull the plugs and do a compression test, all cylinders even at 70-75 psi with 10 revolutions of starter. It drove great, and im sure it still will, but I don't want to make anything worse. Have any idea what could have happened?
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
MIKE yes, that’s crazy but I took it apart and found no valves bent??? I was boggled?? And so I went ahead and did a head gasket and new timing chain and still runs like a champ. It’s my daughters car.
We recently tore my down to get my head resurfaced and when going to put the camshafts back is there any way to tell which is exhaust and which is intake
josue rodriguez well sounds like you need a tune up, do you have a check engine light on? Also check to see if you have a idle sensor. A sensor that raises your idle when A/c is turned on. Clean your throttle body and use Lucas or sea foam in your gas to clean your system.
@@18rollinhard whoever installed it may have used some sealant, so once that sealant breaks free, it should slip right off. If there is corrosion, a puller May be used, but by design, it shouldn’t need one.
The one negative thing that I see is, you driving those inverted E12 bolts in from start to finish with your drill,,,Personally, I always start every bolt by hand to avoid stripping out the threads of their hole. I'm doing a 07 Pontiac G5 2.2 vin-F, Aftergetting everything together, I noticed that my exhaust cam was at about the 11 o-clock position instead of the 10 & 2 position as required on the 2.2 eco-tec. 21 degree high tomorrow-Fun fun!!! NO GARAGE!!! CAN'T FEEL WHT I am doing with gloves & touching metal in cold weather gets to ya real fast!!! I'm hoping that by removing that chain & everything, that it goes back together okay but, I already torqued the cam bolts! That worries me!!!!!! I forgot to straighten the crank & I hope it will be okay to just unbokt everything & redo it this ti.e with the crank at the 12 o-clock position rather then 9-11ish area. Learned what size & type of bolts those inverted E12's are so, I learned something in the process!!! You did a good job & made a good video! THANKS!
sw204me Shop over charge period unless you find a good side mechanic! In which is what I do. So you can google average shop charges on this job and find a better answer. So I research prices as well, divide labor by 2 and that’s what I charge. Round down sometimes lol. But you can always call around to different shops and or go to a parts store and ask if they know any side mechanics to do that job too.
@@ls1camaro92 I'm actually doing it myself, I was just curious what you charged. One shop wants $2200 if they supply the parts, or $726 for just labor and I provide parts. Amazon has a complete kit with both chain sets and the cover gasket for $206, I would still need a valve cover gasket so that would be $1k. Another guy said would do it for $1k, and another said under $500.
I take it that, You did not use any permatex on the front engine cover???? You really should use antisieze on those exhaust nuts!!!! Future you or the next owner will thank you!!!
Gheezus christ mows the grass again. He rented tools 🛠 this time. Lmao at myself (m) for saying so but I’m compelled to do so. The big answer to your small question is: a half a ham sandwich and flat washer is all you need to remove a stuck pulley.
@@18rollinhard harmonic balancer puller yes, unless it is a newer vehicle in some cases u can simply pull them off by hand but in age they tend to rust up or seize to the crankshaft in which case a puller is needed. Do not use the morons method like mr Tennessee there and just whack it with a fucking hammer u WILL ruin the balancer.
