Maintenance and Specifications WINDSHIELD WASHER FLUID Add fluid to fill the reservoir if the level is low. In very cold weather, do not fill the reservoir completely. Only use a washer fluid that meets Ford specifications. Do not use any special washer fluid such as windshield water repellent type fluid or bug wash. They may cause squeaking, chatter noise, streaking and smearing. Refer to Maintenance product specifications and capacities in this chapter. State or local regulations on volatile organic compounds may restrict the use of methanol, a common windshield washer antifreeze additive. Washer fluids containing non-methanol antifreeze agents should be used only if they provide cold weather protection without damaging the vehicle's paint finish, wiper blades or washer system. WARNING: If you operate your vehicle in temperatures below 40°F (5°C), use washer fluid with antifreeze protection. Failure to use washer fluid with antifreeze protection in cold weather could result in impaired windshield vision and increase the risk of injury or accident. CHANGING THE WIPER BLADES 1. Pull the wiper arm away from the vehicle. Pry open the lock cover with your thumb (1) to release the blade and pull the wiper blade down toward the windshield to remove it from the arm (2). 2. Insert the wiper arm hook into the wiper arm (3). 3. While holding the wiper arm, push the wiper blade up and away from the windshield. 4. Close the lock cover. Replace wiper blades at least once per year for optimum performance. 374 2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
