radiator cap not holding at operating temp

[Sniz]

Hey guys

Got my cooling system working pretty well but at my normal 180-200 degree temps the 200 degree radiator cap is releasing pressure and spraying coolant.


Is there another BMW cap I should try or is my cap just old and worn?

I would be happy with a 220 cap or something.


Thanks e36 gurus

Get a new cap if it isn't new. If it is, return it as defective
