As above, there are two lugs coming off the fan shroud, that over time rub on and wear small holes into the radiator

. I don't know if this is the same on the petrols or the 3ltr, but it wouldn't hurt to check........luckily I was only on stockton when it happened, and you cant see where the leak is from coz it is covered up by the same lugs.
After I braised the radiator up, I glued some dense seal type foam, and trimed the lugs to suit. As cutting the lugs took of the flat bit, and it could cut into the foam, I found some old curtain rod ends and trimmed them up to fit to provide a flat edgs.
I can send / post pics if anyone wants to see, but I would suggest you fix it up next service.
Annyone else had this problem.....it is a '99 ute?????
