[W126 Coupe] Running hot

[Pavel]

Group,

I was also wondering what are some symptoms of a water pumps going bad.  Do
they usually start leaking before they go bad?  I have had some diesel
Mercedes that had some play in the fan is that the clutch fan going bad or
is that water pump going bad?  Could it be possible on my sec that my pump
is not pumping enough volume fast enough to circulate through the entire
radiator?
thanks
Pavel
