Cooling system overheating

[MicraKeen]

I've just renewed the anti-freeze in my 2001 K11 Micra 1.4 SE, and now after a run it is overheating - the temp. gauge needle went into the red after about four miles. I suspect an air lock in the system as it didn't take the full quantity of coolant when topping up.

Any tips on bleeding the system would be much appreciated.

It’s less about bleeding and more about pumping.
fill it up to normal levels and squeeze the radiator hoses like you are pumping, it should push the coolant round. Repeat until the levels stop dropping, then run the car until warm keeping an eye on the temperature and levels.
