What size hose do you use for the Top Radiator to Expansion Tank?
Most other hoses for the mod are 8mm, but the top radiator one seems to be like 11mm or around that size.
Do you use 11mm, then get a jubilee clip that will clamp tight at the expansion tank end (8mm)?
Also, do you need proper braided silicone hoses?
I got some from Halfords that didn't specify what they are for, on the website or on the pack, & are not braided, but they look like vacuum/breather hoses, so no good for coolant I think.
