Radiator hose prob?

[wence]

Hello,
Have had this happen twice now on the 12.
The bottom hose that connects to the thermostat comes undone and pops off.
After the first time I changed the clamp to a proper hose clamp instead of the factory push clip things.
It happened again tonight and it looks as if the bottom of the thermostat is reducing in circumference as you move away from the thermostat itself, therefore if the clip is not real tight and happens to move a little it will come off.

I was thinking about putting a joiner pipe in place of the thermostat, anyone done this?

Cheers Mark
