Maintenance and Specifications 1. Start the engine and let it run until it reaches normal operating temperature (the engine coolant temperature gauge indicator will be near the center of the normal area between H and C). 2. While the engine idles, turn the steering wheel left and right several times. 3. Turn the engine off. 4. Check the fluid level in the reservoir. It should be between the MIN and MAX lines. Do not add fluid if the level is in this range. 5. If the fluid is low, add fluid in small amounts, continuously checking the level until it reaches the range between the MIN and MAX lines. Be sure to put the cap back on the reservoir. Refer to Maintenance product specifications and capacities in this chapter for the proper fluid type. BRAKE FLUID The fluid level will drop slowly as the brakes wear, and will rise when the brake components are replaced. Fluid levels between the "MIN" and "MAX" lines are within the normal operating range; there is no need to add fluid. If the fluid levels are outside of the normal operating range the performance of the system could be compromised; seek service from your authorized dealer immediately. 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. 371 2008 F-150 (f12) Owners Guide (post-2002-fmt) USA (fus)
