Hi Guys

Just had a look at the main radiator cap . It looks like its missing the bottom bit i'm not sure. I hope the bottom bit hasn't fallen off into the radiator !!
I compared the main cap with the plastic bottle cap . It looks different ? ( first pick compared to second one )

Advise please guys !
