Have tried back flush without air but water pressure is high but I think its taking easy root.

Was very brown and thick.

Probably not what you want to hear, but it's more likely going to need a new radiator or recore as the hole are tiny and you won't want to use anything too aggressive as it'll attack the metal or solder joints.

 

Has it been ran without antifreeze as that usually helps to inhibit corrosion, but usually speaking it's a semi sealed system so shouldn't corrode as oxygen is kept out.

 

Worth taking it off and blasting in reverse flow, bottom up wards.

Antifreeze not changed in a long time. Radiator was replace when we bought it 12 years ago, 

[GarethM]

It's worthwhile trying to clear it out but 12 years isn't too bad, not knowing what tractor its on.

 

You might look at fitting electric fan if that's an upgrade possibility, as it keeps the operating temperatures much lower which should also preserve the antifreeze.

Tractor is a Fendt 304, electric fan not worth it as only on loader work, will give cleaning it a try and see how I got on.
