Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
HiCustomer Thank you for asking your question on Just Answer.
Are you trying to replace the whole arm, or just the blade?
OK. Here is the procedure.
Use a battery terminal puller to remove the wiper arm if rocking the wiper arm fails to loosen it from the drive shaft.
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten to the nut to 25 N·m (18 lb ft).
I hope this helps.
Take Care, Greg A.
