Need new Serpentine/Auxilliary belt - Toyota Yaris Forums

ras3448 · 10-12-2011, 07:22 PM

My belt squeaks upon vehicle ignition.
Further inspection shows small lateral lacerations along the length of the belt.
I tried a 'squeaky belt lubrication' aerosol spray, to no avail.
I assume I will need a new belt; Autozone had one for ~$17.

Does anyone want to suggest a certain brand/specification of belt?
Know any DIYs w/images for removing and installing the serpentine belt? (entry level DIY-er here

)

I don't have a DIY but it should be relatively simple. I'd buy a genuine Toyota belt, its not much more if any.

Just make note of how it is attached,

then loosen alternator (there are a few bolts, one that needs to be loosened on the tensioner bar which is at top of alternator and two at the bottom where alternator bolts to block may need to be loosened too) until the belt slips off.

Place new belt in the same configuration.

Gently retighten the alternator until belt mostly taught but not too tight.

do you think the tighter it is the noise will still be present???

the belt dressing is really just used for diagnosis.. If the squeel stops after u apply, but shortly returns, belt is dry-rotted and time for replacement.. I suggest OEM belts from toyota. aftermarket belts stretch way to much

If the belt is showing wear, it won't matter how tight it is, it will still squeak and need to be replaced.

Also, if you overtighten, you can throw the water pump bearing. And in that case it just would have been better buying a new belt.

nisyota · 10-14-2011, 09:11 PM

so, pretty much from what you're telling me is that the only belt that won't squeal is the OEM belt??

NZ-FE Vios · 10-14-2011, 09:36 PM

In the long run, yes. Short term any will be fine.

The bottom line is that a Toyota manufactured belt is made specifically to your Toyota. Aftermarket companies takes specs and makes one to similar specification. I'd much rather pay an extra couple of bucks for oem.

nisyota · 10-14-2011, 09:49 PM

how much will the dealership charge me? or, buying online be better?

I doubt that. Toyota (like all manufactures) use a stock size/type that fits any given aplication.
The stock yaris belt is nothing special and is of average quality.

If the Toyota one is of average quality, then what maker would be high quality?

the ones you pay more for

Toyota specs average belts.. but ones that 100% are not crap, so they
will definitely last. [1 in 100,000 failures can still occur like anything else.]

Avoid any crap parts, and the average part will
be assumed to be best quality because it will last forever anyway

Toyota is definitely the best and highest quality belt for oem Toyota applications.

Klink10 · 10-15-2011, 03:23 PM

Ditto everything NZ-FE Vios has said. Particularly the part about overtighten and possible waterpump failure. To me the belt sounds like it has dried out and is loose. Replace, don't overtighten, run it for a bit and then re-tighten. Alot of folks forget that the initial stretch happens almost instantly and the belt needs another adjustment.

NZ-FE Vios · 10-15-2011, 11:02 PM

Thank you. The belt tensioning (or to beware of overtensioning) is the advice of a Toyota tech friend of mine.

ras3448 · 10-17-2011, 04:58 AM

Y'all sold me on the OEM belt. None of the autoparts stores had it though.
Do I need to order online? Like this?:

I also found an old thread about this, but I'm still a bit hesitant to dive in there.
I could use an image to help me visualize my task. MS paint would do.. :)
