Question, is water coming out of the header tank cap......if no, then its not over pressurising!
They are designed to run at pressure!

Can you define a bit more? Is it pushing water out though the cap?

Could this not just be an airlock in the rad pipes?

You are releasing as soon as you stop? Well if the engine is at full temp, then it is going to bubble up and come out.
Standard operating temp is around 95, 97 fans kick in. If you release the cap, air is going to get it, and it will boil...
Check the HBV.

but this should self bleed shouldn't it?
heater blows only hot - that could be HBV. Do a search in the maintenance guides for picture and howto replace.
