Overheating after new coolant expansion tank installed

At this point I’d say adapt a universal exp tank with matching pressure cap? That or try another aftermarket supplier, it can’t be that hard to find a good tank.
What brand is the replacement tank?

Would that work? What's the OEM part number. I'll be glad to help you look.

Well, not exactly.
Plain water will boil at 212, at sea level atmospheric pressure.
One of the reasons to mix plain water with glycol is to raise the boiling point. Lowering the freezing point is the biggest reason to mix, of course, but mixing raises the boiling point, too.
Do you ave a picture of this tank? They make aluminum ones in all sorts of shapes and sizes to retrofit in vehicles that have been modified or no OE replacement is available.
This doesn't sound right to me. If the coolant is flowing through the tank BEFORE the engine heats up, then the thermostat is probably open. But I don't really know this system design. Most rads flow into the TOP of the RAD, then out the bottom of the rad and back into the engine via the water pump. Is the belt routing correct?

See the pic i posted, the radiator doesn't have a cap, the cap is on the tank.
Next to the distributor is the thermostat housing.
The small one you see on the top of the housing is the one that runs along the top of the radiator to the tank.
Ofcourse the coolant runs out of the engine out the top and the water pump is on the left side.
The lower hose on the tank is "branched" to the lower radiator hose which goes ithe water pump.
Yes, there are aluminium ones available for this car, but they cost 200€ which i find a little expensive.
only if it uses 100% water for coolant. With a 50/50 mix of coolant and water the boiling temp is raised substantially.
I'm not using 100% concentrate lol, i'm using Blue G11 50% Premix, which is what Ford Europe used in the Late 80s - Early 90s.
An update by the way, today i went again for a spin with it ( about an hour ) , i don't know if maybe it's because it's cooled down a lot in the last few days but it did not seem to be running too hot at all, temp gauge did not go above the middle.
Try fitting a known good expansion tank. I understand that you want to keep the car original,but... UPDATE . In light of latest post. Don't do anything. It burped.
