how do I replace my 2005 fiesta expansion header tank
It is fitted to the bottom of the plastic header tank, and can be accessed by removing the tank.
This depends on whether the hot water comes from a combination boiler or from a hot water tank with a header tank feeding it. For a combination boiler the fault would probably be at the boiler, possibly from scale in the heat exchanger. For the system that uses the header tank and a hot water cylinder it could be that the float valve in the header tank is stuck an there for it is not refilling the tank or debris has entered the tank and is blocking the outlet.
Reason for question: Plumber left valve open and flooded house The hot water (heater) tank is fed from a 'header tank'; normally in the loft space but can be combined with the main heater tank (fortic). The header is filled from the water main. Unless the header is drained or its outlet is closed off, it will drain down through the open valve of the hot water (heater) tank.
Have a look at this link from the web, hope it sheds some light on your problem. http://www.cavweb-forums.co.uk/showthread.php?p=1920469
The gas tank operates on a vacuum principal and if it's not optimal, then there is a sensor that will activate the check engine light.
where the header tank is for the radiator there is a lid that needs a flat screwdriver to take off. to the bottom right of the header tank. bit hard to explain that.. ha. but its there.
Cracked Engine Block or blown head gasket.
