weeping hole water pump 300sd

[cho]

hi guys

I'm chasing some sudden engine temp increase.. so I would like learn
about water pumps more )

basics and diy for swap is available on the forum but before I swap mine
I would like to ask about weeping hole on it...IIRC on my old one I could
see that the shaft of the pump is revving on the new one (installed a year ago) I can not..? ... stacked pump?

did you have similar issue yet?

p.s pump is not leaking but I can clearly hear some rattling from pumps
direction.....

thanks


cheers,
ChO
