Look at the cistern very closely for a hair line fracture at that hole area if that's fine I would be looking at a new rubber washer or you could swap the whole fixing from either side and see if the leak moves with the fixing set up.

also check the syphon nut, I've been fooled before like this and it turn out the water was leaking from the syphon nut and running along the underneath of the cister and down the long screw,  |

There are about six different leaks that can masquerade as to what the actual leak is on these close couples and then at this time of year you can add condensation for a seventh.
Unless it's an absolutely positive drip, drip, drip, leak I would be very reluctant to take the cistern apart at this time of year.

Shouldn't the rubber cone be inside the cistern so its pulled down to seal as the wingnuts are tightened underneath?

yea there is a rubber washer on the syphon inside the cistern, but if you forget to tighten the syphon up properly, as you're pulling the cistern into the pan with the bolts, the syhpon is pushed up as it hits the doughnut washer, this gives the water a path to escape,  |

I've never seen a close coupled toilet with the two fixing bolts coming through the actual cistern. Only one's I have seen fix through a metal bracket on the bottom of the cistern through corresponding holes on the pan.

most of the new 2 inch syphon ( push button) type toilets are 'screws through the cistern' , Some don't have back nuts, so when the unsuspecting person comes to change a fill valve or syphon, all the water from the cistern comes out right at ya as soon as you start un doing the wing nuts,,eeek,,,,,,, |

Shouldn't the rubber cone be inside the cistern so its pulled down to seal as the wingnuts are tightened underneath? Sorry Tom, I meant the rubber cone part of the bolts, not the siphon. From sweegy's opening line it sounds like he's got them between the cistern and the pan instead of inside the cistern. Attachment DeletedSave |

SaveQuite true but if he installed them as your thinking both would leak and he's got the leak at one spot. |
