hi i have a ford transit witch im having trouble with it had no anti freeze in it and froze over i thawed it out only to find it keepts overheating when i get to 30mph and above my friend told me watch its not the head but he checked and said that was fine then he suggested a thermostat .so i put a new one in still same problem then an airlock was suggested so i bled it still same problem i get no hot air and it cant be the pump because it wouldent bleed otherwise
if this was frozen solid and started the small fan belt which runs off the camshaft on g/box side if the cyl.head may be giving you problems,think this runs the water pump and if it was frozen solid the belt would soon burn out,no water pump and hence over heating,also the auto adjuster for this belt can give problems also,hard to say without seeing your motor but worth a look in this area anyway,good luck
