Probably just old and swollen (like some of us on this forum)...

If you're really desperate, you could try a small bead of RTV silicone in the o-ring groove, then reinstall everything, let it cure for a good 30 minutes before you put pressurized coolant on it again...

im gonna try that .... but is tha usual for it to swell to not fit anymore?...

Yep, more common in hydraulic fluid systems than water-based systems though...Maybe the chemicals in the antifreeze got to it...
