Maintenance and Specifications • Do not use alcohol, methanol or brine or any engine coolants mixed with alcohol or methanol antifreeze (coolant). Alcohol and other liquids can cause engine damage from overheating or freezing. • Do not mix with recycled coolant unless from a Ford-approved recycling process (see Use of recycled engine coolant section). WARNING: To reduce the risk of personal injury, make sure the engine is cool before unscrewing the coolant pressure relief cap. The cooling system(s) are under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Add the proper mixture of coolant and distilled water to the cooling system(s) by following these steps: 1. Before you remove the cap, turn the engine off and let it cool. 2. When the engine is cool, wrap a thick cloth around the cap. Slowly turn cap counterclockwise until pressure begins to release. 3. Step back while the pressure releases. 4. When you are sure that all the pressure has been released, use the cloth to turn it counterclockwise and remove the cap. Engine and secondary cooling system refill procedure The following procedure should be used when refilling the engine or secondary cooling systems after it has been drained or become extremely low. 1. Remove the pressure relief cap from the engine or secondary coolant reservoir as previously outlined. 2. Slowly add a 50/50 mixture of coolant and distilled water to the coolant reservoir until the coolant level is within the COLD FILL RANGE as listed on the reservoir. 3. Reinstall the pressure relief cap. 4. Start and run the engine at 2,000 rpm for 2 minutes. 5. Shut engine off, and remove the pressure relief cap as previously outlined. 6. If required, add a 50/50 mixture of coolant and distilled water to the coolant reservoir until the coolant level is within the COLD FILL RANGE as listed on the reservoir. 48 2011 Diesel (eco) Supplement, 5th Printing USA (fus)
