I got 65K out the German pump I installed in 1997, replaced with a Graf in
2000. Put a new one on when I reman'd the engine over 2 years ago as a
precautionary procedure. Frankly, I think the quality of a German HEPU and
Italian GRAF are about the same, regardless of the coolant used. As I have
conversed with Vanagon owners over the past 15 years, the average life
reported is around 60K. Pretty dismal compared to other makes. The 89
H*nda Accord I traded in 2 years ago had over 260K on the engine with the
original water pump (verified by the original owner and his great records he
kept on it when I bought the car). Owner had replaced the hoses,
thermostat, radiator and other related stuff over the years, but the water
pump was just fine.
