Remove the following 10 screws securing the lower case to the MacBook Pro 13" Unibody:

• Seven 3 mm Phillips screws.
• Three 13.5 mm Phillips screws.

Slightly lift the lower case and push it toward the rear of the computer to free the mounting tabs.

For precautionary purposes, we advise that you disconnect the battery connector from the logic board to avoid any electrical discharge. This step is optional and is not required.

Use the flat end of a spudger to lift the battery connector up out of its socket on the logic board.

Use a spudger to pry up the fan connector out of its socket on the logic board.

It is useful to twist the spudger axially from beneath the fan cable wires to release the connector.

The fan socket and the fan connector can be seen in the second and third pictures. Be careful not to break the plastic fan socket off the logic board as you use your spudger to lift the fan connector straight up and out of its socket. The layout of the logic board shown in the second picture may look slightly different than your machine but the fan socket is the same.

Remove the following three screws:

• One 7 mm T6 Torx screw
• Two 5.4 mm T6 Torx screws

Lift the fan out of the upper case.
