Could anyone tell me what the best brand of a water pump for a
1991 Volvo 740 is.
in the last 4 years i'v changed the water pump 5 times, and every single one had a leak.
is it Genuine, Hepu, Meyle, GMB, Bosch or something else.

Thank you.

 

5 times in 4 years is not the pump.

Regards, Andrew.

 

Hepu. Are your belts too tight?

 

Where has the leak been coming from?

 

it's been coming from the O ring from the top of the pump.
and right now, the pump that i have is leaking from the
bolt at the botom of the pump.

 

no, i don't think so. but i'll check it.
thanks.

 

Have you been changing these pumps yourself? If so, the pump must be pushed up so the mushroom gasket mates with the head. Start the mounting nuts/bolts by hand then lever up the pump using a long screwdriver or something. Need to have that upward force while tightening the mounts.

 

Plus having the mating head surface super clean will help the seal.

 

thanks for the help. it helped a lot.
i'll try to follow your instructions.
