Prius (2010-12) :: Fan Belt Squealing On Cold Days
Jan 14, 2014
You know what I will never miss by have a Gen III Prius? I will never have to listen to my fan belt squealing on cold day after almost killing the battery hoping my car will start.
After our recent cold snap I was surprised how many cars were in my parking lot at work with people grinding away trying to get them to start and the nasty sounds the cars made once they did start. Everything from rough running, not firing on all cylinders, and/or belts squealing.
Now I will admit the Prius did act a little different that day. When the ICE started it did sound like it was working a little harder than it usually does when I first start it. But in all reality at -20degF the ICE started the same as it ever did.

I have a 2006 rx330 with belt squeaking noises on after warming up for say 10 mins on cold mornings, while reaching home I could hear the noises on cold days, the outside temperatures usually 35 to 40 F happens. While driving no noises, only happen on cold days when temperature is above 50 no problem. Should I replace the belts, how many belts are involved ? Tensioner problems ?

I have a mkiv and before I got to work in the morning, I warm up my car for about 10 min. When I start it up the belt squeals. I do believe that it only does it in the morning. Should I have it checked out? i put belt dressing on it last night but it squealed when i started it up this morning so I don't think that worked......

I installed a new Goodyear alternator belt on our 07 Yaris couple months back and it started squealing after the first day and only during a cold start. My past experience has taught me that it's normally due to a loose belt (when belt is new) so I tightened it just a bit. After 3 days it started squealing again. I've increased the tension on the belt three times now and the squealing has not gone away. It's only on cold starts and only for about 1 minute. If memory serves me right there is no tensioner for the alternator belt. It would appear that it doesn't matter how tight the belt is, it still squeals on cold starts.

I just bought a used 93 accord. The engine is in good shape and runs smoothly most of the time, but I have two issues.
First, when I start the engine cold, there is a very loud belt squealing for about 3 or 4 seconds. Is this a common problem and, if I isolate the belt at fault, what should I do about it?
Second, the engine revs (both audibly and on the tach) when I press on the brakes. I've been told by a friend it might be a vacuum leak?

I have a 2010 Prius. Lately it has been in the 80s and 90s here. After my car has been sitting for awhile in the heat (usually during the work day), there is a strong vibration when using brakes. The vibration occurs after I have come to a complete stop, and lasts for 2-3 seconds. After 10-15 minutes, the issue stops. On cooler days I haven't noticed an issue.

My 2011 Prius has the abs light and traction control light on. The car has sat 4 days I go and start it and the lights are on. Not blinking steady. I just filled the car Friday could it be the gas cap not tight?

I have a 2013 Prius with 15k miles, and this happened to me recently for the first time:
- Drove 40 miles
- 24 hours of inactivity
- Drove a very short distance, maybe for 60 seconds, just enough for the ICE to start
- 48 hours inactivity
- Start car, ICE starts, but sputters and sounds like an old, sick lawnmower, and dies after 3-4 seconds. The "check hybrid system" warning is displayed, and I read a P3191 DTC
- Turn off car, repeat three more times, and by the third time, the warning lights went away, and the ICE runs fine again now.
I took the car to a Toyota dealer, and they told me that they didn't see any problems. A friend of mine had the exact same problem with a 2012 Prius, after the same scenario (3 days inactivity with a 60 second trip in the middle of the inactive period).

Well, started to get belt squeak during cold starts. The idler pulley was changed many miles ago for same issue, but it seems to be starting up again. There are NO tutorials for serpentine belt replacement on this gen of RX.

When it is cold (below 30 degrees) and above about 30mph, there is a loud high pitched squeal (rather like the pitch of a squealing hearing aide)that seems to come form the front drivers side. The colder it is, the louder it is.
When I am able to take it in it is too warm to hear it. What might be causing the noise and will they be able to figure it out if it isn't making the sound?

99% sure it's time for brakes. Sounds like the wear indicators are squealing. I'll pop the tires off tomorrow and take a close look. Found a thread on here about doing brakes. Sounds pretty easy.

For a few months now every time I start the car with AC on the belt squeals really loud. It's been getting worse so I need to fix it now. I just don't know if it's just a belt change or something bigger like the actual AC unit. I got the car certified pre owned in 07 and have never changed an engine belt on it so it's probably due. Here is a video of the noise, first part of video is without AC then I turn it on to here the squeal. Is this simple belt change or a deeper issue with the AC? [URL] .....

My daughters 96 cav has a bad squeal coming from serpintine belt. I tried belt dressing and it threw the belt. I didn't notice any cracks/dry rotting on belt. I put the belt back on but it is still squealing.

I thought it was the power steering pump & replaced it and still get the noise. A friend did squirt belt dressing on the belt while running and the sound disappeared for a short period of time, so now my guess is its the belt which is not loose, I went and loosened the four bolts on the power steering pump trying to move it thinking there was a crooked connection between the two pulleys maybe, but no. I start up my car and get a squeal that wiould wake the dead for a minute or two, then all is fine driving. If I drive to the store shut it off for 10 minutes usually starts w/ no noise, looks like I made a charitable donation on the new pump,...also the the power steering fluid is correct

2013 Prius 3 making a squealing or rattling noise when accelerating after car is warmed up. It only does it when the car is up to temperature and when you accelerate slightly harder, like going up a hill or something. It sounds like a pulley or something squealing. It has been to the dealer and of course they couldn't duplicate the noise or see anything wrong. Not to sound funny, but it actually sounds like a hamster running on a wheel. It is very annoying. It is not a constant noise, it only happens under load. It gets louder when the ac is on as well. If you let off the accelerator when it starts the noise goes away. I don't know of it matters but our car has the forged 17" wheels on it from the factory, and the car has 8600 miles on it.

I recently purchased a new (to me) 2010 prius and I've been noticing that sometimes, but not always, I hear a fairly loud noise when lifting my foot off the brake pedal. It sounds like a squeak or squeal, and I want to say I can almost feel a tiny bit of resistance in the pedal when it happens though that could be in my head. The noise does NOT occur when pushing down on the pedal (only when lifting), and it seems to only occur when the car is stopped.

Know that squealing sound a belt makes when it's loose and needs to be replaced? Well what is it when you hear that sound, but you know it's not a belt? It happens intermittently, usually when the car is cold...and it's been happening more and more lately...like whatever the problem is, is getting worse

New to the hyundai world. My belt is squealing under low rpm load. I want to change it out but I don't see how to? I am mechanical I just don't see a tensioner. How would i go about changing it?

2003 elantra when I start the car the belts squeal for about a minute, then whatever I do they start squealing again- turn on headlights, roll down windows, steer the car, turn on ac, anything starts the squealing again. I have had all new belts including timing belt, water pump, etc and it is only getting worse by the day.

Our Prius is only a year old with less than 9,000 miles. Everything has been fine with it and then yesterday I took it out of the garage and started to drive and there was the most horrendous grinding/squealing/scraping noise as I started moving from the front passenger side (UK passenger, so left looking out).
I stopped the car and had a look, as at first I thought I was dragging something, but nothing to be seen. Checked the parking brake was definitely not engaged. I then thought perhaps something is caught in the brake pads and it will go in a bit, however even hard braking didn't seem to change the noise at all.
Carried on (I was going about 7 miles), and as I drove it would gradually get quieter, and then get louder again, with the occasional "clang" sound almost like a spring under tension suddenly moving.
Towards the end of the journey it had started to go quieter again, but with the window down you could still hear constant squeal/grind.
Parked the car, was away for an hour, came back and set off home and the noise was totally gone. Entirely silent all the way back home! Now I don't know what to do - whether it will come back, or whether I should take it in to garage for them to look (even though it's now not making any noise).

So I just traded my old car in for this one and I've had it maybe a little over a month. Anyways, when I go to start it now, even if I just turn on the main power and let the radio start up and the computer and then turn the engine. When it turns, majority of the time it will "squeal" like there something might be going wrong with a belt in there. I know that the timing belt should be changed once every so many miles, just not so sure on my vehicle. Also, if it could be anything else besides that.
