Radiator hose clip

Hullo folks, just got a quick question about the clip that holds the radiator hose on. I'm going to drain the coolant this weekend, and I've read that the hose that needs to be disconnected to drain the coolant is held on by a factory fitted clip that has to be destroyed to remove. If that's the case, is it just replaced by a normal jubilee clip?

Anyone know the right size by any chance? I'm looking to pick one up today but I forgot to check what size the hose is

Also, will removing the bottom hose drain all of the coolant?

Thanks very much for any help

Just pick up a selection of jubilee clips, one will fit. I think it's about 2"??

When I'm changing coolant, I remove the thermostat and stuff the hose in there as well to help flush all the old stuff out. Remember to set your heater to 'hot' to drain the matrix.
