    Torque Spec for coolant outlet hose 11537541992

    Can anyone pass along the torque spec for the coolant outlet hose (part number 11537541992)? This is the hose that runs from the thermostat housing to the water pump and has 2 bolts. I can't find the spec anywhere, even the service manual, and I'm not crazy about tightening without the proper torque. It's on a 2007 335i.

    Thanks in advance,

    Mike

    If it's not in your Bentley manual, just take the bolt diameter & thread pitch, bolt material, and block material, and look it up in the standard torque tables.
    Are you gonna eat that?

    That hose has an O-ring on the engine side right? I would guess it's 8 or 10nm, it's not going to leak if the torque is off a little bit, just enough to keep it from backing out.
