Hi Chris how long a trip does it take for the gauge to give a high reading? My partner van has a fault with the actual temperature sender, which means that at random the temp gauge can go from cold to overheating on the gauge in a matter of seconds, and then back to reading normal again. I am told its a known fault on various models of peugeot. Anyway, If the engine is running and hot, then it sounds to me like you say that its got an air lock. The only other thing I can think of is that the water pump has packed up internally and is not moving the coolant around. Hopes this helps

A jammed thermostat will have the same effect as a blockage and be easier and cheaper to repair. Might be worth looking there first.
Yes, I would look for a thermostat which is jammed shut. Take it out and heat it up in a pan of water on the stove.
If it does open, then flush the block, then the rad with a hose.
he fitted new therostate. also he got told its the water pump. as the rad dos not get hot at all,even with engine running, top hose on rad gets hot but the bottom one is cold not even warm.
Yes thanks G.G.J
