You need to replace water pump seals, you may also need a new shaft and bearings

Time to replace the waterpump seals, bearings and shaft. Make sure to replace all the parts, or chances are it will leak. The seals actually cuts into the shaft causing the leak, most people just replace the seal and it still leaks.
