Worth double checking you've got the protection you think you have Alan using a hydrometer.That was how i learned and discovered the method i've used for 30+ years of flushing, draining then adding the right amount of concentrated antifreeze before topping with water.

Premixing the antifreeze before adding can give false results in as much as you might add what you think is enough antifreeze but because it's already diluted and you can never know exactly how much water is lurking in the system already (or even old coolant) i prefer to get the old stuff so it's just water, drain as much as possible then add the right amount of concentrated before topping up.
