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. Turn the blade at an angle from the wiper arm. Press the lock tab to release the blade and pull the wiper blade down toward the windshield to remove it from the arm. 2. Attach the new wiper to the wiper arm and press it into place until a click is heard. Replace wiper blades at least once per year for optimum performance. Poor wiper quality can be improved by cleaning the wiper blades and the windshield. Refer to Windows and wiper blades in the Cleaning chapter. 273 2010 Econoline (eco) Owners Guide, 3rd Printing USA (fus)
