Loud clicking noise (sounds like the timing belt) from the engine bay.
 

So I came out of a resturaunt the other day, was chatting with my friends outside the place and started my car to get it warmed up while we were still chatting, then I heard this loud clicking noise coming from my engine bay?

Is this normal?
Anyone else experience this?

no, never experience it

why not take it to dealer to check it out since it seems you have a pretty new vehicle????

I started to hear that after i got my pulley and belt installed, guy told me he didnt hear anything and that it was just how the engine sounds. I think the belt is too tight though.

Only does it at cold start, usually in colder weather? Does it disappear after you rev the engine once or twice? If that's the case, I got the same problem. Not sure if this is normal, but I'm taking my TL-S in soon.

Hmmm,
Is it a ticking like an old lifter or a deeper knocking sound. Hopefully it's not piston slap and/or a tight wrist-pin - known to happen however rare.

Could just be the belts but that usually only happens if someone has sprayed belt dressing on them due to squealing etc..

Keep us posted on what the stealership tells ya..

Best of luck guys

If you're talking your TL doesn't it still have an automatic/mechanical belt tensioner? - IE you cant over-tighten the belt? If so, like I mentioned above I would suspect someone sprayed belt dressing on the belts etc.. Belt dressing causes the belt to be somewhat tacky and it sticks then releases causing a ticking type sound.

One never knows however...

It does happen even I rev it a couple times and warm it up for 30 mins.
Maybe I should take it to the shop to get it checked out.

Remove the top engine cover (which covers the heads and surrounds the intake manifold). Get a 3 foot section of garden hose, preferrably with the female threaded coupling still attached. Start the engine and using the hose like a stethoscope with the female part as the earpiece, move the other end around the valve covers first, the the fuel rails and injectors. This is a good way to help isolate the area from which the sound originates.

A few possibles? An out-of-adjustment cam follower. A faulty injector.

Question. Does this sound occur all the time or just soon after starting the engine then go away?

I would do the stethascope trick (5$ at harbor freight tools for mechanics stethascope)
My 01 had a ticking and it was the AC belt tensioner pulley a/k/a Idler Pulley was bad.

Replaced that assembly and she is like a sewing machine again

:thumbsup:

It stays like that even after I drive it and stop and get off to listen.

Well then- its not a belt noise- you need to do the stethascope trick and locate the prob.

Here's what mine sounds like. Is this typical?
Wish there were other TLs to compare around my area...

it is a bad belt tensioner, I had the same problem, the automatic belt tensioner was faulty and was making a knocking noise. I got it fixed, and the motor was dead silent, but then a month later it came back....

we are both talking about the AC belt tensioner right CSM? and you replaced the entire unit- about 80 bucks parts store?
Mine went out recently and was a tickin away bad~
If another similar noise appeared afterwards- next thought would be- is it time for a timing belt and tensioner?

Thanks for the response. Didn't expect it with less than 3K on the clock. I'll have it checked out at the next oil change.

I;m not sure, acura replaced it under warranty. I think it was the one that you can see, but am not sure. All the paperwork said was Belt Tensioner faulty, replaced per acura.

I have worst things to care about right now.

Maybe I'll get both fixed at the same time.

I've been having the same click sound coming from my engine too.. but mine has been more of a chirping sound. It's really annoying.
I have all the engine covers off and it's definitely coming from the area near all the belts on the left side of the engine.

I never heard it when the engine is cold... only when I've driven for a while or when the engine is warmed up. Revving doesn't really change the sound of it at all as far as I can tell. I'll take a sound clip when I get home later.

noise from engine at first start & on cold days
 

I heard a similar noise yesterday, which was amplified when I turned the steering wheel of my 04 TL.

Visited my local Acura dealers. They flushed my steering rack and everything seems in working order (steering fluid was dirty).
