Are you sure it has a timing belt. None of Lexus vehicles that I have owned have a timing belt. They all have timing chains. Have had GS SC LS and GX.

It has a Timing chain. Out of my 2011 manual.

The 4.7 V8 in the previous generation GX and LX had a timing belt so you're not too far off.

I haven't looked that far ahead on mine, but I'm sure it's posted somewhere online. Without the timing belt to address, it's probably minimal (relatively speaking).
