Maintenance and Specifications CLUTCH FLUID (IF EQUIPPED) Check the fluid level. Refer to scheduled maintenance information for the service interval schedules. During normal operation, the fluid level in the clutch reservoir should remain constant. If the fluid level drops, refill the fluid level to the step in the reservoir. Use only a DOT 3 brake fluid designed to meet Ford specifications. Refer to Maintenance product specifications and capacities in this chapter. WARNING: Carefully read cautionary information on product label. For MEDICAL EMERGENCY INFORMATION contact a physician or Poison Control Center immediately; on Ford-Motorcraft products call: 1-800-959-3673 (FORD). Failure to follow these instructions may result in personal injury. 1. Clean the reservoir cap before removal to prevent dirt and water from entering the reservoir. 2. Remove cap and rubber diaphragm from reservoir. 3. Add fluid until the level reaches the step in the reservoir. 4. Reinstall rubber diaphragm and cap onto reservoir. TRANSMISSION FLUID Checking automatic transmission fluid (if equipped) Refer to your scheduled maintenance information for scheduled intervals for fluid checks and changes. Your transmission does not consume fluid. However, the fluid level should be checked if the transmission is not working properly, i.e., if the transmission slips or shifts slowly or if you notice some sign of fluid leakage. Automatic transmission fluid expands when warmed. To obtain an accurate fluid check, drive the vehicle until it is at normal operating temperature (approximately 20 miles [30 km]). Verify that the transmission fluid temperature gauge, located on the instrument cluster, is within normal range. 1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating temperature. 384 2010 F-250/350/450/550 (f23) Owners Guide, 2nd Printing USA (fus)
