If your thinking of replacing your coolant, you may want to give the coolant tank a close look first. If its the original from 99 it may be getting a bit yellow and brittle. You'd hate to put in new coolant and then have the tank rupture and lose most of it.
Changing the coolant tank is a bit of a bugger, but many on this forum have attempted it and lived to talk about it!!!
