Hi there. Thanks for the kudos. If you follow the coolant bleed article exactly as written, it will work fine. Keep watching the tank and top off when you need it. In order to get all of the coolant out of the car, you need to empty the front radiators too. But 4 gallons should be good for replacement purposes. For people reading this in the future, if you're concerned about not getting all of the coolant out, then when you add new coolant, simply mix it a little stronger (60% coolant, 40% water) - that should help...
