Hello.

There are 7 bolts on the cooling system, identified by a number. How to remove them correctly - 1 2 3 4 .... then after cleaning, install 7 6 5 4 ... or the other way (7654 - 1234)?
And what is the clamping force?


Thank you.

    While not critical, screw nearest center should be removed & installed first with the tightening sequence shown below. Final torque should be about 0.2n-m or 2 in-lbs for a 2mm metric screw size.

    Beware that these screws are often coated with a blue or red thread-lock sealant that may require considerable force to remove. This sometimes results in the embedded mainboard nut being pulled out or loosened from the mainboard. If you find a screw that seems stuck, gently heat the tip of the screwdriver so as to heat the screw head which tends to breakthe thread-lock sealant bond.
