The windshield wiper motor assembly installation requires MP grease application on the crank arm pivot before assembly to the windshield wiper link assembly through 3 bolts tightened to 7.5 Nm (76 kgf-cm, 66 in-lbf). The installment requires 4 bolts which need to be tightened up to 5.5 Nm (56 kgf-cm, 49 in-lbf) along with connector attachment. You should mount the cowl top ventilator louver sub-assembly by using 6 claws as points of attachment. Begin by stopping the motor at automatic stop while operating the front wiper arm LH before using a round file and wire brush to clean the serration part of the wiper arm so you can install the arm and its nut tightened to a torque of 20 Nm while manually supporting the arm hinge. The process of repair continues with the front wiper arm RH before installing the arm with a torque of 20 Nm (205 kgf-cm, 15 ft-lbf) but still requires hand stabilization of the arm hinge. The wiper operation under fluid should be performed to verify wiping quality and check that the front wiper avoids vehicle collisions before securing the wiper arm caps.
