Car gets REALLY LOUD during idle every minute then goes away then comes back again.
I have a 03' TL and I was wondering if your cars are like this too. During idle, the car gets really loud. Not an exhaust loud but like its doing something near the engine compartment. My friend heard it once and he has an IS and he said oh my car does that too. He said its the cooling system working. But does it have to work that much? I drive in the city a lot and every time I come to a Stop at a light I would hear it and feel it. It makes the car vibrate a little. It only vibrates a little but not anything to be worried about. And I stop a lot so i hear it like every minute or 2. Then once I start driving I don't hear it probably cause of the engine noise. But I would hear it then it goes away then it comes back and goes away. And when I open my windows I hear it too. I think it sounds like "WOOOOOOO" I was just wondering is your TL like this too? Is it normal? I never had a car like this before.

is it the driver side cooling fan operating? that will come on and off during traffic or just sitting in your driveway 10 minutes will make it operate
or perhaps a front motor mount is broken causing a vac leak? they are vac boosted and fluid filled mounts on front and rear

Is it only when your a/c is running? The a/c compressor and cooling fan will cycle on-and-off like that, even more so when idling in traffic. When the a/c compressor clutch engages, the engine will rev up slightly, and the cooling fan will come on as well. Turn off your climate control, or AUTO button, and see if you notice it then. If not, it's probably just the a/c making normal noises.

No, my ac is always off. It's not hot enough yet. But my fan is always on just to keep air flowing. And I hear like a whirring noise when I turn my fan on. Its not loud but annoying. But yeah that loud noise that my car makes is probably my cooling fan but it goes on and off like every 2 minutes. I don't mind it going on cause its cooling my car but it makes a really loud noise. I was just wondering if its my car or that's just how the 2G Tl's are.

have you looked at the cabin air filter for the internal noise-
should change filters every year and most cars never had it done before

ck the blade on cooling fan for any looseness or runout or tightness in turning the blade
Motors do wear out eventually- another ziner had this recently-needing fan motor

The whirring noise when you turn on your cabin fan could also be debris in the blower motor fan. Leaves and stuff get in there and make a noise just like a putting a card in a bicycle spoke.

For the cooling fan on the radiator, just lift the hood, listen for the noise, and check for the source. Maybe the fan blade is rubbing against the shroud, maybe you will notice the fan motor is causing the noise.
For the cabin air filter and blower, you will have to remove the glove box and go from there. There are some DIY's here that will walk you through it. The blower motor fan will be the most difficult part; it's not complicated, it's just a PITA to get it out and back in.
Time for a little Yankee ingenuity! (pun intended)

I don't hear anything unusual but I swear when I open my hood I hear like a little squeaking sometimes and it sounds like its coming from the only belt that you can see moving. I just got my belt tensioner replaced and I feel like the sound came after I got it replaced. Which belt is the only one u can see moving.

maybe they got the tensioner in crooked or a cheap unit and its failing or...
the ac belt tensioner will make a lot of noises over time- mine did for 40kmiles~
Was the belt replaced with the tensioner?
was the tensioner really noisy and thats why replaced?
popping the glovebox out to get the ac/cabin filter out for debris-leaf inspection is about 15 minutes- if the filter has been changed before that saves you 5 minutes with the scissors removing the cover piece
See diy

when you turn the fan on (by pressing auto) the ac is automatically enabled, so it may or may not turn on depending on whether or not the climate control system thinks it's necessary (mine seems to be on all the time, even in 45 deg weather). only if you see the "A/C OFF" displayed in the temp readout is the a/c really off. so if you're not seeing that, you are likely hearing the compressor cycling, which is sort of loud with the windows down.

Maybe it is my compressor. My A/C is never really on. But one time I heard the noise and once I heard it, I turned my fan off and the noise just stopped suddenly. So I thought hmm... But then 2 minutes later the sound came back. I think it's normal.
I only got the tensioner replaced but it fixed my A/C squeaking noise and a clicking sound around 1k-1.5k revs.

everyone needs to run the ac at least once a month for 15 minutes, or 30 is better if you dont use it several times a month normally
Need to move the freon so the oil in it keeps o-rings supple and prevents leakage
ck both fans for any wobble- shake the blade gently or differance in feeling- passenger side runs with the ac on as compressor runs- it comes on to pull air thru its radiator-heat exchager so it cools better when not moving or moving slow---airflow thru the rads makes things cool
CAUTION driver side fan may come on at any time if the car is not overnight cold-
pull battery neg cable for extra safety- make sure you have the radio code -
it will lock when batt power disconnected- in case its being stolen it wont work without the code

DIY Cabin Air Filter change... Its a good idea to do anyway!
PS: Instead of a Dremell you can use cutting pliers just fine (I posted some pics on the last page when I did it)...

we need to update the diy--dremel is not needed to cut the plastic tabs on air filter cover
Kitchen scissors, box cutter etc --cut the tabs on one side of part- then bend back and forth to snap off other 2--its made to do that
Turn plastic cover sideways to install after new filters- has end tabs that fit into special slots and a screw to hold it in

I have quite a few pics when I did it - i made a quick summary of what i found helpfull...
I changed my filter and I thought I would throw in my 
CDN.
First off, thank you for this guide! It really was an amazing help!
My filter had never been changed...
I found using a pair of wire cutters / "snippers" I got a really really clean cut. This type of plastic really cuts nice - and makes no mess when using these cuters.
Make sure you put a rubber floor mat and a garbage bag down before starting to prevent a mess from all the dust.
I also found that wrapping a flat screwdriver in hockey tape really helps the job and avoid any scuffs.
When I had to remove my fog light to repair a chip/hole the tape-warped screwdriver was a lifesaver getting it out.
I also wrapped a pair of needle nose pliers - useful when removing the clips.
(The cutter pliers are 2nd from the right. They are close to ~30 years old and still sharp! (They've seen their fair share of battles).
Here is the junk that was in the "tunnel" before vacuuming.
A lot of leaves from my street considering I've only had the car a couple of weeks.
The filters were black and had a lot of junk in them.
Even a piece from my microfiber wash glove was in there.
I replaced them with FRAM 99.9% effective baking soda / carbon filters. It was what I could find and they were only about 26$ CDN - as Can-Tire was out and more expensive. A box contains 2 filters - so if your phoning around for prices!
I just poped them into the holders and put them in.
My air has a lot less dust coming out of it now and it actually made a difference in my allergies.
