coolant leak

[white 330ci]

i have a small coolant leak coming from the bleeder valve right next to the fill cap.

i have tried tightening the cap but that didn't help used

any ideas?

i will check the o-ring tommorow, when it has cooled down

White 330 ci. I don't think it's a major problem.
I remember watching the technition bleeding the
cooling system of my 2000 328i when I had the
coolant changed in June. The screw seemed to
have a spring around it and it probably has some
sort of seal which dried out or split. I'd take it to
the dealer first and ask how to remove it.

ya i will tried putting oil around the seal but have not had time to test it, if that doesn't work i will just replace the cap.
