NOTE:
It is not uncommon to repeat this procedure 3 times.
- Fill the hydraulic cooling fan reservoir to the MAX level using Motorcraft MERCON® Multi-Purpose Transmission Fluid.
- Apply 20-25 in. Hg of vacuum to reservoir for 2-3 minutes. Remove the vacuum pump.
- Start the engine and turn the A/C on MAX. This will run the hydraulic fan. If a whining noise is heard, repeat the procedure.
