My 2015 MP3 500ie (3rd gen) currently has about 40K miles on the clock and on its second waterpump.
The bike is driven 80% motorway, with the revs sitting between 6-7K rpm.
As of yesterday, it has started to leak yet again from the waterpump weephole / drain tube. Sometimes it drips only a drop or two, sometimes it leaves a puddle, and sometimes it is bone dry particularly if the bike is driven practically on a daily basis.
The last pump I put in was a complete pump with engine casing, not just the seals, in the hopes of prolonged pumplife. Apparently not.
What is the consensus for average pump life?
FYI, the coolant is renewed every 2 years on the clock with fresh pink G12 spec coolant.
