Ford Mondeo Heating

[clubsceneuk2]

I have a ford mondeo which is blowing cold air even though the heaters are on full.

I have been told it could be the thermostat or an air block. Can anyone tell me how to see if its an airblock and how bleed it.

Thanks

with heaters on and engine warm, feel hoses running thru the bulkhead - if one is warm and one is cold then u may have an airlock. Cold hose will be the return pipe, so disconnect and pull off slightly until air clears from heater matrix - it will gurgle and spurt until clear. You may find there is a bleed screw on the pipe which will make it easier for u. If both pipes are cool then thermostat is probably jammed open and will need to be replaced.
