im getting one to replace the one on the radiator not the higher level reservoir near the turbo.
people use them on both to increase the pressure in the cooling system and this increases the boiling point of water so its less likely to over heat, but doing this puts extra pressure throughout your cooling system and risk rupture or leaks on all your old stock hoses, the shit hose clamps could blow off, your plastic end tanks on the radiator or reservoir could leak or crack, head gasket leaks can happen on older head gaskets or even cracked head etc
my caps not holding enough pressure so im buying 2 new ones just in case
also the surbru parts dude said they dont make the standard radiator one in a 137kpa which i was surprised as its a factory fitted item
