Hi All
Now it's getting colder and the frost and snow is on its way I think it's time to check the strength of the antifreeze So what would you
Gent' suggest the ratio should be ?
Jacko
50:50
If its anything like the last 2 years.......200% antifreeze.
Antifreeze is activated by water so 50:50 is the best.
Just checked mine.
-45 deg.

So you couldn't have just pure antifreeze in the wine, er, I mean rad?
I thought it had to be a mix because antifreeze was rather corrosive to radiators...
I've got that episode of the simpsons stuck in my head now where he gets sent to france.
"Antifreeze dans le vin?"
^^ He's right ya' know!!
Didn't realise that was how it worked either, so had to go look it up 
Thats Ethylene.
There are other types but generally its 50:50
And antifreeze is also added because of its anti corrosion additives.
Pure water is poison to your rad and engine.

I'd go 50 : 50
My Freelander runs a clever mix in its 6litres -
3 litres of anti freeze , and the oily residue from the time the oil cooler let the engine oil blow out the header tank.
It will never freeze - header tank looks like a beach on the gulf of mexico
The import thing is use the correct type of antifreeze generally pink/orange is OAT 5 year+ longlife coolant , and blue/green is old fashioned
ethylene glycol 2year life antifreeze. They shouldn't be mixed because the corrosion inhibitors are incompatible.
These aren't the only variations for instance Asian manufacturers used a Red ethelene glycol coolant, and you wil also HOAT coolant.
Some coolants particularly some HOAT coolants claim they can be used mixed with either type however if you want extended coolant life you must
flush the old fashioned antifreeze out the system completely.
Also when buying particularly if buying from a supermarket take care to check if you are buying pre-mixed coolant or raw antifreeze
concentrate.
Remember also that antifreeze will increase coolant leakage, so carefully check foe leaks.

That is the only because of the corosion inhibitor that are added to antifreeze, the inhibitors degrade with time, 2 years for conventional antifreeze 5 to 10 years for longlife OAT coolants.
Going back a few decades most antifreezes were much more corrosive than tap water because they often contained methanol at anywhere from 25% to 90% and the corrosion inhibitors then in use only had short life and the coolant had to be replaced with water during the summer months.

You know according to the book mine stays for the life of the engine and never needs replacing...
Isn't that a con though so you'll kill your car and by a new one like keeping the same transmission fluid for life?
Quick question, mine doesn't need doing but for future reference and for anyone else who doesn't know, how do you drain the system?
50:50 defo.

I refer you to my earlier post - engine oil is a great corrosion inhibitor when mixed with anti feeeze.
