Coolant leak throughRad Cap

[invisible]

As per title, I performed a coolant flush and refill several months back before sticking the car away for a bit.

Will be sorting out the niggles an putting car back on the road soon but noticed after i'd done the coolant change and taking it out for one last 'sporty' drive before storing whne came back the coolant was slowly bubbling out from under the rad cap.

Cap seemed to be on ok and I hadn't noticed it before (however coolant was low and weak which had made me do the change).

Is this just likely to be me needing a new rad cap or could this be caused by somethingelse as I wouldnt have thought pressure would be released through the cap if issues.

Temp readings in car are fine.

If I need a new cap any particular pressure I should be looking at?

New rad cap needed mate, the rubber seal inside tends to perish and seep water. Not a big prob just replace and job done
