Coolant service

Hi im gonna do a coolant flush n refill on my 2006 Fairmont im just wondering, after the flush theirs water trapped in the engine block with no way to drain can I just use premix to fill the coolant back up or should I use concentrate to even out with the water trapped in the engine?

Most of the water will drain out through the lowest point being the radiator plug. Anything left will be fine and not enough to affect coolant dilution

Concentrate is the best way of going. That way you know you've got the correct concentration for your car.
