Current opinions on water pump as preventative maintenance?
Hi All,
Been lurking this forum every so often since I got my 128 just over 5 years ago.
As these cars age, I'm curious about up-to-date opinions regarding replacing the water pump (or other cooling system components) as "preventative maintenance."
Is it:
a) The electric water pump is a ticking time bomb, even on a 128 where it's less stressed.
or
b) Early failures were likely manufacturing anomalies. If it's working, leave it alone unless you see symptoms (excessive fan running, temp warning, etc). But keep up with regular coolant flushes.
My car:
2009 128i 6mt coupe
N51
119k miles
Lots of short trips/heat cycles. Well-maintained but by no means babied.
All original cooling system except for the coolant itself (last flushed just before 100k).
