I pressume Darrsi suggested the rad flush to get rid of any blockages which may cause extra pressure in the system and therefore cause things to leak but other than that I'm not sure how a rad flush would help with the problem you mentioned. Properly cleaning out the system with a good rad flush once in a while ain't a bad idea though. Tightening the clip will defiantely help if it was a bit loose though.
