Maintenance And Timing Belt Change Schedule

[viclykewhoa]

Here are a few questions:

I have a '99 GS300 with about 88k miles on it. I just changed the drive belt by myself seeing that it was cracking.

When does Lexus recommend the Timing belt be changed?

When should I flush my transmission?

... change my brake line fluid?

... change my power steering fluid (is that even necessary)?

What needs to be done at 90K miles?

Thanks to all the regulars and everyone else who provide fellow Lexus drivers with your knowledge!

It is recommended that the timing belt be changed at 90K miles but I have also heard from a guy at Lexus that you can wait until 120K. From what I understand, you don't 'flush' the transmission, just drain it and replace fluid. The tranny fluid, differential fluid, and antifreeze should be replaced at 30K, 60K, 90K etc. Do you have the owners manual for your GS? Part of it addresses scheduled maintenance and tells you what needs to be down at various mileage intervals.
