My ford focus has no radiator cap. After draining the cooling system do I refill it thru the over-flow bottle under the hood?

Yes you sure do! Where else could it go?

You fill it through the expansion tank. Just keep adding coolant.

If the reservoir has a pressure cap and there's no radiator cap that reservoir is where you fill the cooling system.

It's not an overflow bottle it is part of the circulation system

The coolant bottle cap is a radiator cap. Fill at the coolant bottle.

You can fill it through the top radiator hose before you attach it to the thermostat housing. The overflow bottle needs to be filled to the cold level. Let the engine run for awhile to make sure it does not overheat before driving it. Sometimes air bubbles in a closed system will create an overheating situation.
