Wiper Transmission, Front

Installation of the windshield wiper motor assembly starts by attaching the windshield wiper motor to the link through 3 bolts where torque reaches 5.4 Nm (55 kgf-cm, 48 in-lbf). Next install the crank arm after applying the washer and nut, while aligning the matchmarks between the crank arm and windshield wiper motor and torque the crank arm to 17 Nm (175 kgf-cm, 13 ft-lbf). The crank arm pivot requires MP grease before installing the windshield wiper link arm. The windshield wiper motor and link assembly requires 5 bolts for attachment and torque should be set to 5.5 Nm (56 kgf-cm, 49 in-lbf) while connector connections should be performed. The left-side front wiper arm LH installation requires rounding the wiper arm serration with a file and the wiper pivot serration with a wire brush before using the nut to secure the front wiper blade in its proper position and torquing it to 21 Nm (214 kgf-cm, 15 ft-lbf) while manually supporting the arm hinge. The same cleaning process should be applied to the front wiper arm RH before installing the 2 nuts to 21 Nm (214 kgf-cm, 15 ft-lbf) settings while verifying proper functioning through wiper tests with water or washer fluid to prevent any obstructive behavior. The installation of the cowl top ventilator louver RH requires you to attach 8 claws before installing the louver which needs a clip to complete the process. Rephrase this process to connect the cowl top ventilator louver on the left-hand side. Secure the cowl top hood seal by using 8 clips for attachment. The work requires connecting the cable to the negative battery terminal before performing initialization when some systems need this step upon negative (-) terminal cable reconnection.

The first step to remove the front wiper motor and linkage involves removing the front wiper arm head cap followed by taking off the 2 nuts from the front wiper arm LH. The removal of the front wiper arm RH starts with unscrewing the nut. Begin by detaching the 8 clips which will allow removal of the hood to cowl top seal. Then remove the 8 claws and clip from the cowl top ventilator louver LH after repeating the same steps for the cowl top ventilator louver RH. The process requires disconnecting the connector before removing the 5 bolts which will let you take out the windshield wiper motor and link assembly. To remove the windshield wiper link arm from the crank arm pivot of the windshield wiper motor assembly start by using a flat-head screwdriver taped at the tip and disconnecting the components as needed. First remove the nut with its washer before separating the crank arm. Write down the positions for reinstallation on both the crank arm and the windshield wiper motor. There are three bolts which need removal as the first step to separate the windshield wiper motor.

Connect the cable to the negative battery terminal and perform initialization, as certain systems require this after reconnecting the battery.

Install with the 5 bolts at a torque of 5.5 N.m (56 kgf.cm, 49 in.lbf).
