4.6L SFI engine (check cold) NOTE: The brakes on the 4.6L engine vehicles are powered by power steering fluid from the power steering pump. The fluid level in the power steering reservoir will rise and fall due to the amount of charge in the brake booster accumulator. Therefore the following is required. 1. Check the fluid level when the system is COLD (allow at least one half hour after driving for the power steering fluid to cool). Locate the power steering reservoir mounted to the front upper left-hand corner of the engine. 2. NOTE: Brake fluid and power steering fluid CAN NOT be mixed. Only add brake fluid to the brake master cylinder reservoir. Only add power steering fluid to the power steering reservoir. 3. Visually verify that the fluid level is above the MIN line adjacent to the reservoir "sight window." If the power steering fluid is below the MIN line, remove the cap and add fluid in small amounts until the level is between the MIN and MAX lines. Reinstall the reservoir cap. 4. 5. It is normal for the fluid level to be above the MAX line after the brake pedal has been pushed several times with the engine off. (If you want to double check it; restart engine and turn steering wheel to full right turn, then full left turn and then turn engine off and re-check fluid level. It should be between MIN and MAX line.) 233
