Read through the ES forum. Dozen and Dozen of owners of 10-15 year old ES's have needed to replace their radiators and even sometimes their whole engines due to the use of aftermarket antifreeze and / or tap water. These owners didn't realize (and many still don't) all they had to do to prevent this self inflicted engine destruction is to respect and trust the advice of the Toyota engineers to use only a 50/50 mix of red Toyota Long Life Antifreeze and distilled water in their cooling system (it was the coolant mixture Toyota installed in their cars to begin with.

In your owners manual it explains the RX330 uses a 50/50 mix of pink Toyota Super Long Life Antifreeze and distilled water. Your owners manual also says this factory fill is good for many years or 100,000 miles and strongly advises that you use it at replacement time. This new antifreeze came out in 2004 and since it will be several more years before most owners need to change it, Toyota & Lexus dealers generally aren't even stocking it yet, but you can special order it.

You should read the factory repair manual to learn the procedure to change the coolant because sometimes a special air bubble bleeding procedure needs to be followed to prevent possible overheating and engine damage when changing the coolant.
