airlock problem?

[pinkvdub 0]

1.8 16v. i cant seem to get any cold coolant to my top rad hose and any hot to my bottom, now i got advised on here a couple of days ago to change the thermostat so i did even though the other one seemed fine, i tested the new 1 and it opend at just below boiling in a pan of water on the cooker,

theres just no coolant flow again!!! back to square one with my 3rd thermostat now so i refuse to change it again! heater matrix is nice and very hott!

 

ive tried everything, squeezing all the hoses, leaving the cap off until boil then squeezing, driving the car for around 10 mins then stopping to let it cool and taking the cap off and driving for another 10 mins or so, filling all the hoses, temp gauge is nearly through the roof, head gasket it brand new water pump is belts are, rad cap is, expansion bottle is,switches are. everything! is!

 

im gonna blow this engine up soon i just cant understand what the hell is going on, but i think its gotta be airlock still. i dunno what to do please help people!

so i didnt want to but i left the car at idle from stone cold for about 30 mins the temp gauge read just over 3/4 (115) of the way wich i really dont like to do lol, as usual the fan neva came on even though the switch is to hot to touch and ther is deffantly power getting to it(just need it to flick so it will make the fan come on, yes its my third switch so it cant be faulty surely. either way once the bottom hose got very hot the top hose went empty of coolant but i cant put anymore coolant in the expansion bottle or it will go over max mark, so im guessing it still major airlock somewhere in the system. any ideas?

Have you tried filling the system up from the top of the rad and the block up from the top hose?
