thankyou simon.i fully understand that the waterpump does not need to be disturbed or removed. what i was trying to suggest was that the release of belt pressure and re-applied was in itself a "disturbing " action on the bearings / seals within the pump itself. this may of course have been an assumption by other members rather than being a case of a pump that was ready for change anyway. if the belts were in need of change then the pump was about ready for change in any case. did the o.p say somewhere in the thread that the pump had been changed along with the belts recently ? if that indeed is in truth correct and the job has been done then as you say either poor quality parts or workmanship seems the likely culprit. ... regards stefan.....
