I have a '01 GS430 bone stock,
I was wondering what all I should do to it? oem/factory stuff and mods welcome.

So what all is needed for the 60k or 80k mile tune up?

all I can think of is the timing belt, plugs, and fluid changes.

anyone know the mileage intervals for the various items?

car is starting to run a tad sluggish, it's at 84k miles with stock everything but tires.

I don't have the owners manual supplement that shows what's all needed.

Thanks,
Acmed the dead terrorist

You can get a free owners manual through lexus.com. If you feel your car is sluggish then its time to do those maintenence you just mentioned. Are you doing it yourself?

I am capable of most repairs.
So far I've done the necessary stuff such as tires, brakes, trans flush, coolant flush, you know the routine stuff but my owners manual says to check the "supplement" to the owners manual. I have NO idea where that book is located that's why I thought to post here on the forum.

I went to the dealer but they're not much help, they said the plugs and differential fluid never needs replacement/servicing! excuse me? never? I don't think so.

So as it stands, I have no idea when to do the timing belt or anything else.

Timing belts are commonly replaced at 10 years or 90k miles accoding to the manual. When you do that you might as well change the water pump, drive belts and plugs. There are DIY's here that can help you with that. I'm surprised dealer was not helpful. Seems kinda odd to turn down sure business..

Check online again at lexus owners site, the supplement is the "owners manual maintenance manual".
It'll have all the info you need.

It should be available as .pdf or if you take Lexus up on the "order" a hardcopy, you should get both books.

Read up, then come back with your questions.

thanks for the info, didn't think of trying Lexus.com first.
