Quick question from a total Lexus newbie.

I'm going to get the timing belt & water pump replaced on my 2002 GS 430.
Since I'm going to be paying for all that labor anyway, what else do you recommend I get replaced?

Thanks in advance!

 

Camshaft seals, serpentine tensioner and fan pulley bracket.

 

If you have brown rad tanks, might as well replace that too, while you've got it removed. Not a big job on its own though, should you choose to forego it this time.
