It should. I don't believe they changed anything major between 1999 and 2000.
You can make anything work, but if you want a direct bolt in and electrical connections, No.
No there have been three body changes between those two years.
If its another ES 300, then yeah.
Yes , the 3.0 litre V6 engine in a 1999 Lexus ES300 has a timing BELT
Its in the Cluster.
Under the intake manifold.
It's behind the glovebox if you have the nakamichi stereo
i need to see the diagram fir the timing belt
it would cost more than $2,000
nothing their both the same
should be on top of valve cover This picture will help you find the PCV valve http://www.clublexus.com/forums/es300-and-es330-forum/418700-2001-lexus-es300-pcv-where-is-it.html What you really need to know is that if your engine has been desludged the L shaped plastic PCV valve would have been replaced with the metallic, straight screw in PCV valve first introduced in 2002.
