The installation process for the hatchback rear wiper motor starts with attaching it through three bolts that require a torque of 5.5 Nm (56 kgf-cm, 49 in-lbf) while simultaneously connecting the connector. Then the next step includes inserting the rear wiper motor grommet. A round file or equivalent tool should strip metal particles from the wiper arm serrations while a wire brush should clean the wiper pivot serrations. The rear wiper arm must be placed correctly into its designated position with a hand-held arm hinge as you apply the nut with torque set to 5.5 Nm (56 kgf-cm, 49 in-lbf). You should install the rear direction for the wiper arm head. The last step involves disconnecting the back door trim board to attach the cable to the negative terminal using 5.4 Nm (55 kgf-cm, 48 in-lbf) torque.
