Overheating Problem

Hey guys



This problem has seriously done my head in i hope you can help..... i have an MGZR 2005 1.4 105+



Last week my car started to overheat and noticed bubbling from the expansion tank and lost my heaters. so the first thing i thought was my thermosat so i changed that, still over heated and bubbles. so i had a spare head gasket so changed this head skimmed etc put it back together still over heated. so i took it down to the garage for some tests. all come back fine pressure test fumes test etc, they did not know the problem and was going to change what i have already done. ive checked the water pump all seems fine there.... the radiator hose gets hot but not the heater pipes when press the pipes over and over the water goes down so i thought there might be a blockage somewhere so i took all the pipes off from the heater matrix flushed the radiator etc still no luck.... if its a air lock its a bloody good one but the expansion return does not seem to return problem i.e pumping the coolant around properly but i dont no.

so here we are i have no clue where to go from here am out of ideas...



Help! lol
