The hose clamp on the top radiator hose on my 5.0 AU is a strange one... It looks like a conventional hose clamp but it is all round on the top and has no screwdriver slot in it.
Anyone seen one of them before? And how would I go about removing it should I need to replace the radiator hose in the future? I'm guessing a set of pliers perhaps?

Yes...it means it wasn't P.D'd properly back when it was new.
P.D. = Pre Delivery Check.
That "cap" is removeable with a pair of pliers, and you will see a normal screwdriver slot.
It is a "shear bolt" for want of a better word, for when they do them up in the factory...do them up till they snap off.
Chances are, several of them will still be on there.

Cheers for the reply. Thats excellent news... Many thanks mate.
Yet another reason why I love fordmods so much, A wealth of knowledge.

my au still has them on the lower radiator hose, so did the mrs au untill i changed tha radiator and hose...

I did often wonder about those. Felt quite silly when I worked out you just pulled the end off with pliers.
