My water pump is original with 1,285,883 miles on it. It doesn’t leak, and I have no complaints. Should I be concerned? I have a new OEM cartridge I carry around if it should start leaking. I change my coolant every year. I’m not worried about it, but every once in a while I read something that makes me think twice. ??

With 1+ million miles on it .. Maybe rebuild or replace it the next time you have to replace the fan clutch or have to remove the drive belt?.
