Either in the glovebox or on a label on the inside of the hood should be all the amounts of fluids needed. If you are flushing the system, bear in mind the anti-freeze does not need to be but 50/50, the other half water. Unless you live in a very cold climate.If not flushing, wait until cool, then remove radiator cap.It will say do not remove, because normal filling is thru the coolant bottle, but thru the cap you can see how low it is. If it is not out and you don't live in N. Dakota, I would buy one gallon, fill it at the cap until full. If it never fills, add water until it tops out. Chances are one bottle is plenty to keep the water from turning to ice inside the engine, which is the whole purpose of anti-freeze. It has a lower freezing point.
