2005 Buick Century Windshield Wiper Arms

The recommended torque is 30 N.m (22 lb-ft).

You need to turn the ignition ON, turn the wiper switch to DELAY, turn the ignition OFF when the wiper arms are paused at the bottom of the wipe pattern, disconnect the washer hose from the wiper arm, remove the wiper arm nut cover and the wiper arm nut and use the J 39822 to remove the wiper arm from the wiper transmission.

You need to install the wiper arms onto the wiper transmission, and hold the measuring device at a 90-degree angle to the wiper blade while maintaining the following distances: right arm: 97-107 mm (3.82-4.21 in) from the end of the wiper arm to the air inlet screen, left arm: 125-147 mm (4.92-5.78 in) from the wiper blade tip to the air inlet screen. You can apply thread-locking compound, GM P/N 89021297 (Canadian P/N 10953488) or equivalent, to the wiper arm nut, install the wiper arm nut and the wiper arm nut cover, connect the washer hose to the wiper arm and operate the windshield wipers and inspect for proper operation.
