You shouldn't need to bleed it again. The 2.1l coolant system bleeds
itself to a certain degree. If you were replacing something like a
water pump or head or the radiator then you definately want to bleed the
system. Even your expansion tank, it is a good idea. However after you
bleed it at the radiator the system will continue to self bleed. Every
morning just check the level in the expansion tank and top it off. Also
be sure that the tank behind the license plate is up to the full line
and that the hose is connected to the expansion tank cap. If you top
off the expansion tank for a day or two the level in the expansion tank
should stop going down.
Hope this helps,
