I went looking for cooling system capacity, but got bored looking through the 671 page repair manual. I've always flushed the system with water and then put in 2 gallons of antifreeze, finishing off with water, just like Palf70step and Stocker have said. Pretty sure that the system is close enough to 4 gallons that unless you live in the frozen north, you'll be close enough for freezing protection.
