Does anyone have the official instructions on how to do a proper coolant flush on the SC430?

I'm trying to help a friend who has a SC430 in Indonesia which was a grey import into the country and therefore the local Lexus dealer will not help him service the SC430.

Thanks.

According to the '06 service manual, they recommend inspecting coolant every 15,000 miles and changing it at 100,000 miles. This also has to be gauged by the climate you live in and on visual inspections. Without question the coolant is changed when replacing the timing belt at 90,000 miles or sooner.
