Replacing engine coolant.

In response to the impending artic conditions, I bought an antifreeze tester.
On testing I found my coolants freeze protection was minimal giving a reading of -7c (one floating disk). Now I am in two minds wether to try to top up with concentrated anti freeze somehow without removing hoses if possible or going all out and draining down and refilling the system.

How hard is this, and what do you do with the 10 litres (according to my manual) of old coolant.
