That clicking noise is the camshaft driven high pressure fuel pump for the direct injection. It's a mechanical unit, the noise starting up is a dry start which is normal for these vehicles. They are really bad about dry start ups.
@@rogepunzalan Really nothing you can do about it, it's normal on these vehicles. My wife's 2012 Traverse has 245,000 miles on it and it's done it since new. I am not a fan of the V6 engines in these cars, they make a lot of noises on start up with the cam phasers and that mechanical pump. Just use a high quality synthetic oil and keep up on your maintenance.
My 2016 Acadia just started rattling when I start it only. Never did it before , was completely quiet. Now rattles during crank then sounds norm . The car only has 34,000 miles on it. I change the oil every 3500 miles full synthetic. Anyone have any advice? I might just sell this and buy a toyota.
I was told mine needed a new timing chain and would require pulling the engine which was very expensive. They also suggested that for only $1000 more I'd be better off having them drop in a whole new engine. I'm just going to drive it until it dies.
The clattering noise is the camshaft actuator which I verified with a scan tool which showed an extreme angle on one actuator right at the point the noise could be heard, which didn't appear until about 2 seconds after the engine was started. I had the cold start clattering noise in an 08 3.6L that seemed to be linked to oil drain back. I replaced the 5W30 with 10w40 a higher viscosity oil particularly at start up and have not heard the noise since. These motors are hard on oil and with 5w30 the noise would appear at about 3000 miles on the oil. This is a common problem with this engine and still is even in brand new 2017 vehicles.
Ok. Thanks. I had replaced the cats and the mechanic hesrd the noise at startup. He also said go to 10w30 cause its common on these cars and said its quiet the vehicles that go to his shop. Thanks.
+Craig R hi OP would you be so kind and follow up on this video? Have you ever discovered what was the problem? Mine's doing the same thing, down at chevy dealer they told me it was timing chain. So i replaced it, didn't do jack..
los impulsadores son hidráulicos y al descargarse hacen ese ruido. cuando la bomba de aceite carga y eleva la presión se quita ese ruido... unas personas utilizan aceite mas grueso.. yo personalmente recomiendo usar un filtro de aceite con válvula de presión para que no deje escurrir todo el aceite al carter y mantenga la presión de aceite.. saludos.
As a technician for gm, I can tell you they all do it. Especially if they sit for a few days. The 3.8l has always done that, but it's not something that will need to be addressed.
My 2011 chevy traverse does the same noise at the start but it goes away right after, the problem is its check engine light on and need smog check 😞 can someone help it reads Code P0017 crankshaft position Camshaft position Correlation bank 1 sensor B
Yo tengo una 2010. Si no le pones el aceite recomendado te hace ruido y el daño es progresivo yo le pongo 5 w 30 sintetico. Y le digo ala persona q lo va hacer el cambio si tienes de ese haslo y si no lo hagas el cambio
jorge umana si wey me queria vender a mi otro tipo de aceite y le digo no wey quiero que el que lleva original 5w30 y que por mas barato me daba otro nombe al ultimo sali rayandosela tambien tengo una 2010 lo bueno que aun no hace este tipo de sonidos amigo, la tuya si hizo o como fue?
Acabo de comprar una 2010 y tambien hace ese ruido, le pongo el 5w30 sintetico y como quiera lo hace. Me dijo un mecanico que necesita nuevos tensores de la cadena de tiempo
arule8180 hey my 09 traverse was doing this my friend works at gm he had me buy a new vapor canister valve and it worked I put it on n less than 10 min it's on amazon for under 30$ it's an original ac delco part the part number is acdelco 214-2137 hope it helps
Mine had same issue, replaced the timing chains and now problem is worse, im looking into valves and actuators that are the ellectrical part. I wish i did a better reserch before putting my money in tomit

@quack quack I Drive a 2012 Traverse and I hear the noise... so you say use a higher grade oil to stop the noise?
Hey jordan and others mine did u switch to 10w30?? And did it improve??
@@pinoiboi13 I'm using 10w30 and it's helped with the noise. He stated use 10w40

I hate when people post issues by video and never follow up when its resolved. Was it a tensioner or not?...
I had no idea anyone replied to my post... They changed the timing chain and the issue went away.
@@BootlegCraig damn! How much did that cost?
@@davidba7418 Was covered under warranty - otherwise I would have sold the car.
Was the problem diagnosed?

May be actuators. Heard of them going "bad" and locking up or not working properly, associated with timing chain issues....
Might be the timing chain

Juan carlos Carrillo Soto como se pide ese tipo de filtro amigo? Y de aceite solamente el indicado que marca el manual verdad 5w30
buenas tardes juan carlos una pregunta me comentaron que tiene que ver ese ruido con las cadenas es cierto
Como se ordena ese filtro?
My 09 Traverse is making the same noise
Sounds like you need new timing chains. Better fix that quick before they break in there and really fuck up your engine.
They changed them and I haven't had the issue since.
@@BootlegCraig how many miles/km do you have now ? If of course you still have it .
Mine does a little ticking its normal for these . But not like this one on the video.
What happened?
Did anyone switch to 10w30 and see a difference. Mine makes the same sound
I put 5w30 synthetic 4quarts and 1 quart if lucas synthetic and still makes that rattle.
I have a 2011 Buick enclave that makes the same rattling sound I'm going to try to up the oil to see if it really works thank you.
@@bigtu1214oil up? 10w30? Did it work I have a Buick Enclave doing this..
They all do that mine does to
Just like the rest of GM's 3.6L, needs timing chains, guides, and tensioners. Noise will be gone. 👍
Thanks for the reply! They ended up putting new timing chains on. Not sure about guides and tensioners, but it has since gone away.
Craig R Glad you got it resolved. Unfortunately, its common on every GM application with a 3.6.
I had my timing chain and kit replaced, noise is still there
What kinda mileage was on it 🤔

i got the same now did yours got fixed?
