ye man get it replaced if u dnt hav any service history, ur best off replacing the water pump at the same time as its driven off the timing belt, jst to save u having to go back thru it all if the pump fails at a later date, and ul need 2 relace the belt tensioner aswel as the ball bearings in them go to shit on some occasions, parts alone shudnt cost any more than £60-£70. if ur getting a garage to do it the laybour is wat will kill u man so mayb u knw a mechanic or sumbody on here cud do it in the cheap as a nixer ha

id offer to do it but i live in paddyland!!
