When I've done my vehicles in the past you work out the amount of fluid required as a percentage of the total coolant in the engine. This always leaves you with a couple or so pints of anti freeze left over.
So what I do now is put the lot in and top it up with water, then you can chuck the can away and save yourself tripping up over it for the next 3 years.

There is no set ratio; a ratio that would work fine for me would be completly useless in the likes of siberia.
The antifreeze should tell you at what ratio it will give you protection down to, remember to factor in wind chill.

Err... why? Wind chill won't affect anything that's already at ambient temperature - only things warmer than ambient. If the ambient is -5 with 15 degrees of wind chill your land rover isn't going to get colder than -5.
That's not to say that to a person the apparent temperature would feel like -20, but then if your average person was down to ambient temp they wouldn't be feeling anything at all

Engines are effected by wind chill the same way we are, it might not be -30, but our bodys are being subject to cooling to that temperature, so is an engine, as long as its warmer than the surrounding air which it will be soon.
Any object that creates its own internal heat will find that heat is removed from it faster if the air around it is moving.
Take the jiggle pin out like the army landrovers, they remove the jiggle pin, so all the time there is a little warm water going to the rad.

grunt has it right, the best thing to do is take yer bottom hose off the rad(remembering ter wear wellies) when its emptied, refit the bottom hose, pour in a gallon of antifreeze then top up with water, start yer engine and look fer leaks, if none visible, shut the bonnet and go fer a brew

Think I will be doing this myself over the hols.
Will the system self prime/bleed?
Costco, holts anti-freeze, gallon for a £5.

Thanks lads I will take on board all you have said
BTW I lived in Canada for a few years Winnipeg and
you could stand on the corner of Portage & Main in
winter and the Temp with wind chill would be -60
BTW PPS They say that flesh freezes at -16 in one hour
so if you were in the nude you would be dead..........

When you fill it, remove the filler cap from the top of the thermostat housing and fill it from there, unless you have the earlier one where its the top of the radiator, or if no filler hole is fitted, through the expansion tank. Each system is designed, if filled the right way, to avoid air locks.

Did my 90 and Disco today, flushed the rad and gave the engine a little clean out in the 90. All good.

Yes, engines are affected by wind chill while they're running or while they are warmer than ambient air temperature. It might take longer to warm up than it would if there was no wind chill, but wind chill still won't make it get colder than ambient temperature, because that's not what wind chill does.
If the engine is off and still warm from being run it will still be affected by windchill and will cool down faster than without windchill, but only until it reaches ambient temperature, where it stops getting any colder because that is what wind chill does.
Let me say it another way - if your coolant is liquid at ambient temperature, wind chill will not cause it to freeze, no matter how cold the ambient temperature, or how great the wind chill.
You do not need to factor in wind chill when calculating how much anti freeze to add to any engine, only the minimum ambient temperature that the engine will encounter.

Your start your engine on a really cold day, and drive fastish into the wind, thus the wind chill is now blasting your radiator, now you have a frozen radiator, its happened in army LR's in cold climate, thats why army LR's for cold climate operation have the jiggle pin removed.
