this green cap is stock with all 940's and runs at 1.5 atmospheres of pressure. the idea being the coolant will hold more heat. this increases pressure throughout the cooling system and as the car ages makes for potential troubles .

this cap was stock n 240's and holds .75 atmospheres of pressure. this puts far less stress on your cooling system but also hold less heat as it less than room pressure.
i throwaway every green cap i ever see on any volvo that comes my way and install only the black .75 ones.
