Sorry that I didn't see your message earlier but the SC430 is my wifes car so I don't prowl this forum very often. I spend my time in the 350Z forums. If you really want to get all the information regarding the service of any Lexus model I would suggest going to the service manual site TIS. You can get a 24 h subscription for about $10 and then just save the pdf files. That's what I did and you can get the repair manual for every model and all service areas.
