hello

After replacing two waterpumps i noticed some things:

1) an original waterpump from Volvo: makes a whining noice while in use.
Ran 2000km. It did it from the beginning, one month ago

2) an NOT original waterpump does the same immediately after the
install. and is 2 weeks old.

Is this normal? We filled it up with normal water, cause the systems
have to be flushed one more time.
Can normal water cause these noises? Are the pumps broken? Are it the
belts (not orginal volvo)?
The belts seem not to loose and not to tight.

For both pumps: back to thes store and change while under waranty?

Or doesn't do this noise any harm?

greets and thanks,

lex
 
Are you sure the noise is coming from the pump? could be the timing belt
tensioner or the alternator. you could rule out the power steering or a/c
compressor by starting the car with these belts off. If the water
pump spins quietly by hand,doesn't have any play and its not leaking then its
ok.
