Serpentine Belt noise

[Dan Dibble]

Is our belt the only one squeaky?? When you start it up the noise is bad for about one minute. Belt dressing will quiet it for a few days.

Its a Toyota belt with about 50,000 miles and has been doing this for about 40,000 miles or three years


Any ideas?

Thanks, Dan

Replace the belt? Was this belt a Toyota OEM s-belt?

Yes it is OEM. I installed it about four years ago, when I changed the timing belt.

The belt looks good. I could change it, but I was hoping someone had a fix I was unaware of.

Was it OEM Toyota or OEM Lexus? Apparently, they are different.

Really!? Not that I need to know...but wonder what/why the difference?

According to LXRunner, the LX Serpentine belt is narrower than the LC belt. Mentioned a couple of weeks ago.

Yep, it helps for a few days only. And then that dressing slightly penetrates to belt material, gets sticky and collecting even more dirt.
Finally, once using belt dressing, permanently damage the belt.
Squeaky belt - is dirty belt. $20 - new belt. And clean up pulleys...

That seems strange to me. However the engineers must have had a good reason eh?

99LX engine pulleys narrower than on LC. Don’t know for what reason. My guess – to reduce weight and engine drag?
I know in some cases they even use lighter then for Toyota bolts with "grounded" heads .

Can we gather some statistics on belt widths? Everyone go and measure your belt and report the width in millimeters, the year of vehicle, and whether it's a LC or LX.

Ok.

I have a good friend that works at a toyota/lexus dealer in Mobile Al. I will call him and see if the part numbers are different.

I talked with toy/lex and the part numbers are the same between the two. Their was a part number revision but it applied to both trucks.

You going same way like I did: Idea to save $ on Toyota shop versus Lexus, then they told me it is same number like Lexus.
I found that it is different just when removed old one.
Then went to Lex. dealer, got right one and return prev. back to Toyota.

If that will help for reference I just measured it on my 99LX: 21mm

Digging up an ancient post...

I have a 97 LC that has an incredibly squeeky s-belt. I have done the NAPA belt dressing trick...works for a day or two. How difficult is it to relace? I am pretty handy (pulled the radiaitor once...replaced the inner seal in the front end, etc.), but don't want to start anything that is a real PITA.

Thanks,

^^^ '97 model year LC, North American anyway , should be an 80-Series therefore a V-belt.

 

[dbrooks]

V-Belt

OK - what is the PITA factor to replace them?

 

[spressomon]

^^^ I've replaced alot of V belts on different rigs over the years but never owned/done them on an 80-Series. The others weren't more than 1/2 . If you truly have an 80-Series I'd recommend you post your question in the 80-Series forum...for a little faster answer.

If you have a 100-Series with the V8 then it has a serpentine belt. And this is also a 1/2...er maybe a 1/4 job to replace.
