Who makes OEM Serpentine belts for 04 Lexus LS430?
I know the timing belt is made by Mitsuboshi. Does that mean serpentine belt is also made by Mitsuboshi? If that so, would following match be the one?

Mitsuboshi W0133-1628747 Drive Belt
Part #: W0133-1628747 | Mfr #: W0133-1628747

Or is it Bando?
Bando 6PK2240 OEM Quality Serpentine Belt


This aftermarket is probably better than OEM.
Gates K060882 Multi V-Groove Belt

Ok, I read Gates and Goodyear Gatorback serpentine belts are the best out there.
Has anyone here installed Gates Sepentine belt and what is your experience? Is it a perfect fit and is it noisy (compared to OEM)?

I'm gonna bump this old post because the dealer told me I need to replace my serpentine belt and I'm having a hard time finding enough info on it. Can't seem to find the belt on Sewell either.

Try ' auto parts warehouse ... $26 for the Bando and $28 for the mitsuboshi... First link I clicked on, you may even find cheaper price searching online elsewhere

Ah, I saw the "drive belt" on sewell earlier, but I was not sure if it was the same as a serpentine belt. I researched and results were inconclusive; some people said it's the same, some people said it's not. Is the drive belt exactly the same thing as a serpentine belt?

That is correct

Mitsuboshi is OEM. They also make the timing belt.

i got the Gatorback belt a while ago...completely satisfied, utterly silent. Forget how much but maybe $30? it solved the minor squealing sound I had on a belt 80k old.

When I was shopping for a new drive belt I found one for the Lexus 4.3 engine and one for the Toyota 4.3.. The toyota belt was like a quarter of an inch shorter and cost $10 less.. I bought that one. Seems they are trying to make an extra $10 off Lexus owners ?!? Same exact belt minus a 1/4 inch.. no issues.. silent..

Can I ask how is it the "same exact belt" if it's a 1/4" shorter in length to start? Such a critically engineered part of the engine, I'm just saying why would you be looking to save $10 especially if it's shorter than OEM. The timing belt is designed with extremely exacting specs and tolerances, with a belt tensioner whose purpose is to pick up any slack in the belt. If you start with a belt that is shorter than spec, my concern would be that the belt gets stretched to the correct OEM length rather quickly, then begins to prematurely wear and stretch even more due to the extra tension placed on it cause it was slightly smaller to start. Why take such a chance? The risk / reward isn't there for me.

I cant explain why it works so well. It's amazing isnt it?

I personally think it's a giant conspiracy.

Very interesting. I'm looking for a new serpentine belt for my 2004 Lexus LS 430. OK so what is the best brand quality belt I can buy and just as important which is the quietest. Thank you..

You'll get a dozen different answers to this question and they are mostly just opinions. The Toyota belt (90916-02586) is a fine choice and not prohibitively expensive at around $50. Allowing a Lexus or Toyota dealer to install it will turn in to a $200 affair.

You'll find 6 brands under the "Std Replacement" category. I wouldn't be afraid to use any of those 6. Stay away from Autozone...

Mine looks fine, but I'd get the OEM Lexus barnd, pay $50 or whatever and call it a day!

This is where it gets interesting-
I really didn't want to bring this up AGAIN but it's always worth consideration.

Lexus of South Atlanta, prob the most prominent online Lexus parts retailer, list 2 serp. belts for the 430. One is $48.64 and the other is $80.34.
https://www.lexussouthatlantaparts.c...&searchString=
The $80.34 option reads BANDO. Bando has facilities worldwide but they manufacture belts in Itasca Illinois. A Bando belt for the 430 can be purchased all day long on the internet between $15 and $20 dollars.

Now you got me scratching my head!
