The starter is located underneath the intake plenum/manifold. For the work it takes it might be wise to replace the entire starter.

For the cost I would just replace the gasket.

What kind of noise? Does the engine even turn over?

You will only have to remove the glove compartment.

Take a look at this site: http://www.nav-tv.com/index02.htm

Not meaning to sound rude but, flat bed it.

Do you know where the test connector is under the hood? Jumper OP1 to E1 with the engine running and see if the fans spins at high speed. Also I had a car come in with the fan not running and it turns out the cooling fan ECU (behind the glove compartment) was unplugged.

Hi, this is my first post. (I don't own a Lexus, I work on them) Just today I installed XM radio into an ES330 using a kit for a LS430. I had both wiring diagrams in front of me, double checking wires in the kit against the LS430 diagram and then finding the same wires in the ES330 diagram. Every wire going to the XM unit has to be used. It took some time but it works fine. (The ES330 was equipped with NAV and Mark Levinson) Dealers in my area (Northeast) are doing this. :D
