Hi,

Planning a coolant flush on my Twinair, and wanted to get everything in, and ready.

So I want some decent hose clips for the radiator hose.

The petcock on the radiator is difficult to get to, and produces a pathetic dribble, so I'm going to take the hose off.

However, I can't find a thing online about the size of clip needed.

Not a single clue.

Does anyone know what outside diameter the radiator hoses are?

Any model would give me a clue.

Cheers, Peter.

I don't know the exact size off the top of my head, but it's probably around 45mm.
No tape measure? If not, assuming you at least have some kind of ruler, wrap a piece of string or paper around the pipe and measure it to get the circumference, then use a calculator to get the diameter.

1.2 is 42mm not that may help
