Help please!! possible head gasket gone!!

[J-D]

hi there i cleaned my exspansion bottle out th other day becuase the water was lookin minging!!! took it for a drive and it drove fine for about 15mins then over heated!! i stopped it soon as a saw this happening and rralised the water was bubling out of the radiator into the exspansion bottle, i have checked the oil and theres no sighn of water in there still runs fine just keeps on doin it. i no this is possibly a heead gasket blown but didnt no if i have done somthink wrong when fillin the water levels back up? i always keep it topped up on good oil and water and it hasnt done a silly amount of miles so i hope its not a head gasket and ideas people!?!?!?

Was the engine hot when you cleaned the expansion tank out?

It could just be an air lock in the cooling system. I don't know the correct way of getting it out for Micra's, though. On the old Pinto powered Ford Sierra you just left the top off the spanny bottle and topped it up until it stopped going down after emptying/flushing the cooling system.
