generaly this will work, but tipos are notourious for airlocks in the matrix.Trancendental said:Fill up a Bottle of Water+Anti Freeze
Switch on your Engine
Turn your Heater knob to Full Heat then set it to Full Blast
Open your Radiator cap
Remove the Bleed screw from the water pipe that enters the top of the radiator (follow it backwards it should be clearly visible)
Fill up the radiator with water and look at the water coming out of the bleed valve, when that water it becomes free flowing like a fountain, close the bleed screw.
continue filling coolant until its at the required level
Close Cap, Switch off Engine and you are done.
could be that someone put the heater hoses on the wrong way. try swapping the pipes round for each other . was problem on an old 127 gt about 15 years ago. swapped pipes around and heater worked . if wrong way round water wont flow thru the heater matrix. worth a try. as it only takes a few minutes to check. or the valve on the heater matrix might not be opening to let the water flow. as for bleeding there should be a bleed screw on one of the heater water pipes or try bleeding it by unscrewing the water switch. when a perfect flow of water comes out tighten it upbryan3075 said:Hi the only bleed valve is on the radiator,the two heater pipes get very hot but only blows cold air,is it posible that the problem is the head gasket?

that sounds awful, afraid i might have the same problem. my coolant keeps bubling out the bottle. is that a symptom? or do i have an air lock?craigg9700 said:bryan is the heating getting hot at high revs? and also the temp dial moving hot and cold a lot ?
i have a fiat bravo 1.2 sx 16v on a T reg and i took my car in on thursday and sad to say it was my head gasket blown so hot water was leaking into my cylinders :bang: , hope that you only have an air lock though because it has cost me £360.72p for new parts and fitting ( gasket , head bolts , cam belt and tensioners , oil and filter then fresh coolant and the head skimed) , let us know how you go on ?
Gurgling is normalbluejohn125 said:I've read this thread and tried to clear an air lock in my blue 1.4 ie, but I don't think it worked.
Symptoms - gurgling, sloshing sound from heater when starting up first thing, also water level in expansion tank low.
Temp does not go past half way with heater on as we alll know the trick, If ever you are driving and your car starts to over heat. You put the heaters on full blast and it draws hot air away from the engine, hence the temp staying low.bluejohn125 said:The heater gave a good blast of hot air so I assumed all was well, but when I started it up a while later the gurgling was back! It may be my imagination, but the temp doesn't get up to half way now either (is this better or worse?).
