Plumbing Header Tank
I am planning on using a Peugeot 205 header tank. In the 205 one pipe goes from the base of the tank to the bottom radiator hose and a second pipe
goes from the header tank into the thermostat housing. There is a third pipe that I think is just an anti air lock device.
My question is, is it necessary to effectively plumb the header tank into both top and bottom hoses so that presumably water is circulating through
the tank rather than it just being an expansion tank.
Please forgive me if this is so basic but this is the first installation of this type I have done. All others I have done used a standard Cortina
radiator where this did not arise.
Any advice gratefully received. Than you.
John

You can get away with only 1 pipe to the top of the rad if thats the high point.
If the engine outlet is higher then it would be best to tap one from there also.
No need for anything to the base of the rad or engine, I suspect the extra pipes are to allow you to fill the system from the header tank, just pluck
off the top hose and fill from there.

In my setup the header tank is plumbed into the feed to the water pump (the lowest point), also a small bleed hose to the highest point in the system

When thinking outside the box doesn't work any more, it's time to build a new box

My tiger and pinto setup caused some confusion when I had to repair the water pump but it is similar to the 205 one you mention and works thus;
Bottom of header tank goes down to bottom of rad. Bottom of rad 2 goes to bottom of water pump. Large pipe on thermostat housing goes to top of rad
and thin pipe on top of the thermostat housing goes back to the header. A third outlet on the waterpump is blocked off (heater outlet).
In my system the header tank is pressurised and is part of the circuit of water with water continually flowing into the top of it.
I put a bleed screw into the top left of the rad to help bleed air through too which is well worth doing.
