405 overheating coolent blowing out filler point even when left to cool down ie next day.
Heater has not been working for sometime, not sure if that's relevant. Have changed the thermostat a few months back, seemed to help for a while.
At first the temperature would get very high and after driving a while would drop back to normal.
Now however after a couple of miles the red light and STOP sign comes on. Any thoughts please.
No cash to rely on a garage/dealer

You dont say what 405 model you have, 1.4 petrol, 1.6/1.9 petrol or 1.7/1.9 diesels.
Now assuming the basic principle that the coolant needs to flow around the engine,and the path of the coolant is through the cylinder head, engine block and the heater matrix and you have no heater working, I would imagine the heater matrix guts have collapsed. This will mean a blockage not allowing any coolant or restricted flow to circulate. Coolant only circulate the radiator when the engine is hot by means of the thermostat.
Heater matrix failure isn't uncommon, and are readily available £35-40 parts price.
Continued driving will mean you will blow a head gasket and warp the head - so stop now.
The worst bit may be removal of the dash board to gain access to the matrix inside the car.
You will need ensure that the cooling system is bled free of all air, this can be quite tricky. Its worth completly draining the block and raditor and changing the whole lot whilst your at it, wont need doing then for a couple of years.

Guy's I really appreciate your help.
It sounds as if not getting it looked at sooner I have blown the head gasket.
Did not really have an option as short of cash.
Still you live and learn.

Head gasket on a 405 isn't the end of the world is it? I would imagine it's quite straight forward as long as you haven't got an Mi16 or something weird.
