Not been in amongst mine but.
Is it the thermostat bypass relief valve?
Is it a one way valve spring loaded so if it opens fluid would come from engine then join to the main thermostat housing after it?

think we discuss one in the lower hose as some time.

May i ask a daft question plse

could the wrong cap fitted on the extension tank also cause hoses to blow off etc plse

thks
 
If the pressure setting of the cap is too high, it will have no effect unless there is excess pressure in the system, in which case something will have to give.

many thks, it was just out of curiosity and makes sense, me being a sad old git enjoy learning new things
