  Q: How to replace the wiper arm on Chevrolet Express 2500?

  A:

  Start replacement by moving the wipers to their park position followed by detachment of the washer hose elbow from the air inlet panel. Unscrew the protective cap from the Wiper Arm nut before taking out the nut. Use Wiper Arm puller j 39822 or battery terminal puller whenever the Wiper Arm fails to disengage from the Drive Shaft when rockered back and forth. Pull away the Wiper Arm after you free it from its position. Place the Wiper Blade over the Wiper Arm before mounting the arm to the Drive Shaft. Make sure the Wiper Blade center points with the black locating dots on the lower windshield center. The wiper arms must remain in their correct position because installation tags specify left and right sides. Affix the Wiper Arm securely using the nut which you must place next to the air inlet grille to reach 26 n.m (19 lb ft) of torque. After covering the nut install the washer hose elbow back onto the air inlet grille panel then test the wipers for correct functioning.

  Q: How to service and repair the wiper arm on Chevrolet Express 2500?

  A:

  You should set the wipers to park position before removing the washer hose elbow from the air inlet grille panel. Lift the protective plate while unscrewing the wiper nut before taking out the Wiper Arm's nut. When rocking the Wiper Arm does not work to detach it from the Drive Shaft try the Wiper Arm puller (part J 39822) or a battery terminal puller instead. Move the Wiper Arm side to side to detach it from the Drive Shaft before taking off both components together. Install the Wiper Blade onto the Wiper Arm before fitting it onto the wiper Drive Shaft. Also normalize the wiper arms because each Wiper Arm carries a corresponding indicator stamp to prevent swaps between the left and right side. Place the measuring tool at right angles with the Wiper Blade and put the Wiper Arm onto the Drive Shaft. Keep a 70mm (2.75inch) gap for lh Wiper Blade tips and 65mm (2.56inch) gap for rh Wiper Blade tips starting from the air inlet grille panel. Frankly attach and fix the nut by turning it to 26 n.m torque before you put covers back and place the washer hose back into the air inlet grille panel. Test the wiper function and examine if the system works correctly.
