Do you need to change coolant every year on your car ?? 

No, should only top up if required (unless there is a problem, eg: a leak), or in most cases these days, change every 10 years.

i do mine every two years 🙂

What do Ford recommend?

The antifreeze does two things a) inhibits corrosion, b) inhibits freezing.   They say you should change it as it loses its effectiveness , I don’t know in which way a or b or both.   I mention this in case some people living in milder climates don’t give it a thought

Most likely both ways since a lot of people just top the coolant up with tap water if it's low.

The coolant mix is supposed to be 50/50.

I've seen it sometime ago now that the coolant does (a) inhibits corrosion, (b) prevents freezing, (c) contains a water soluble lubricant for the pump.

Replace every 10 years or sooner in harsh conditions

I had mine replaced @ 88,000kms.Car is 5 years old,they do say every ten years,just had it replaced with the equivalent OEM long life coolant(8 years).As I have had not had the cat that long,I had all fluids replaced,spark plugs & new brake pads as well.Car drives like a dream.Next job is now to get a small dent taken out of the rear right quarter panel,get on to my PDR guy for that one.These are just a ‘cracker’ of a car!
