Temp gauge fluctuating between hot and cold, a gurgling sound coming from engine when hot, hose from thermostat to radiator is cold at radiator end when engine is hot. New thermostat fitted, changed water pump,changed radiator, heater working fine,tried running engine with water filler cap off. Any idea's what could be causing this problem please and how do I get the air out of the system.

Have you tried taking the thermostat out,and running the car with out it,to see if you have the same problem ?If you have tried every thing,and it sound as if you have done what most people would check,I would go back to the thermostat,Just hope you have not got a head problem,(Im still thinking your thermostat is not opening ? is your rad,getting hot ?, is you cooling fan working ?
