    I’m in the middle of a cooler service on my pair of QSM11’s. I’ve found pretty much everything I need except for the torque specs for the heat exchanger core and the aftercooler core and housing torque specs.  <br /><br />

    Can anyone point me in the right direction?

     

    thanks in advance

    8mm screws into aluminum?   = about 150 inch lbs with lots of really good grease– But you also need to account for thread depth..

    IMO, this should be done by ‘feel’, nothing else.
