Hi & greetings from Germany.

I am new in this forum. I own a 57 series 62 Sedan de Ville which is now water leaking at the waterpump.
I've got a question regarding this problem: Has the 57 Cadi a specific waterpump or do waterpumps of other modell years fit as well? On pictures the 56, 58 59 pumps look similar.

Does someone know the answer? It is highly appreciated.

Thanks in advance
from a currently very hot Germany.
