2005 Ford Galaxy heater blows cold air

Could try bleeding cooling system . If head gasket gone it could cause air in system , making heater blow cold and overheating . A sniff test ( block test ) will tell if gasket knackered or not .

Thank u very much for quick response. Actually, I have allready carried out the gasket test with a mechenic. He put a flask with blue color water and was constantly pumping that in my vehicle expansion tank. But the color of blue water did not changed.
My question is what is the best way to take out the air lock from cooling system. And another thing I was driving up the hill today and when I started going down the his the nice and warm heat started blowing out. So I thing there is massive air lock but I can't take that out. Please, any help would be much much appreciated. Bcas I make living with my car. Thanks .....

Could try this suggestion re. bleeding from Galaxy forum ,

Next to the wiper motor / end of pollen filter are the 2 pipes that go to the front heater matrix. This AFAIK is the highest point in the cooling system and most likely place for airlocks.

Picture shown has the scuttle tray removed (3 bolts) to get better access.

No bleed valves AFAIK.

Thank u vry much Mr Whittinghame for ur interest and help. As I drive this galaxy for my living so I am vry anxious to get that back on road. U know that the weather is getting vry cold and I do need heater as well as my passengers.
But today just now I did one another attempt to bleed out the suspected air lock. What I found that I left the expenssion cap open and let the engine to the normal temperature I put on the heat to minimum level after one hour my vehicle got heated and I felt before that the heater is blowing hot air with open rad cap as the engine got hot the air was getting hot as well I sqeezed all the hoses and pipes for possible air lock I kept abit engine in high rev. So the heater blower hot hot air for one hour as I felt that the cooling fan kicked in for 4 times with opened rad cap. I was very delighted that the suspected air lock has gone away. Atlast I put the rad cap on tank and moved away foe test drive. Would u beleive that for ten minutes it was very hot blow from the heater but as I rev the engine and put more gas for fast driving the air started cooler and at last the heater again blow cold air.
I done this experience be looking at ur reply that u suggested to bleed from the two pipes of matrix. I will definitly try that as well now. But can u please tell me what actually is this. Apart from heater my gal runs very good. Please let me know I will b waiting for ur response and I m following u.
Millions of thanks
God bliss u.
