Bleeding the radiator (air in cooling sytem)
There is a 10mm or so sized screw in a fitting in the upper radiator hose above the radiator. Does anyone know if this is the bleed screw?
I suppose I could unscrew it when it's warm and see if air leaks out...
For those who don't know what I'm talking about, there is usually (always?) a way to bleed air out of the pressurized coolant system. This is usually a screw of some kind at the highest point in the system.
BTW, this is on the Cooper S which has, I think, a different set up than the Cooper.
