I ordered an aftermarket water pump for my X350 and unfortunately the replacement pump is not a complete unit and requires the cover section from the old pump. The workshop manual only states the torque settings for the three retaining bolts (25n) and not the ones I need which relate to the seven smaller bolts that hold on the pump cover.

Can anyone tell me what the correct torque settings are?

Also the replacement pump shipped with a paper gasket whereas the old pump contained a metal gasket. Will this gasket type make any difference?

 

I would use the old metal gasket if it is in good condition and use sealant with it.

 

Pulley bolts are shown at 24Nm, by the way on the next page.
