Maintenance For vehicles with overflow coolant systems with a non-pressurized cap on the coolant recovery system, add coolant to the coolant recovery reservoir when the engine is cool. Add prediluted engine coolant (Motorcraft Orange Antifreeze/Coolant Prediluted) to the FULL COLD level. For all other vehicles which have a coolant degas system with a pressurized cap, or if it is necessary to remove the coolant pressure relief cap on the radiator of a vehicle with an overflow system, follow these steps to add engine coolant. 1. Turn the engine off and let it cool. 2. When the engine is cool, wrap a thick cloth around the coolant pressure relief cap on the coolant reservoir (a translucent plastic bottle). Slowly turn cap counterclockwise until pressure begins to release. When you are sure that all the pressure has been released, use the cloth to turn it counterclockwise and remove the cap. 3. Fill the coolant reservoir slowly with prediluted engine coolant to within the FULL COLD level, or between the MIN and MAX marks (within the COLD FILL RANGE), as listed on the engine coolant reservoir. If you removed the radiator cap in an overflow system, fill the radiator until the coolant is visible and radiator is almost full. If coolant is added to bring the level within the COLD FILL RANGE when the engine is not cold, the system may remain under filled. 4. Replace the cap. Turn until tightly installed. Cap must be tightly installed to prevent coolant loss. Whenever coolant has been added, the coolant level in the coolant reservoir should be checked the next few times you drive the vehicle. If necessary, add enough prediluted engine coolant to bring the coolant level to the proper level. If you have to add more than 1.0 quart (1.0 liter) of engine coolant per month, have your authorized dealer check the engine cooling system. Your cooling system may have a leak. Operating an engine with a low level of coolant can result in engine overheating and possible engine damage. 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. 2. Before you remove the cap, turn the engine off and let it cool. When the engine is cool, wrap a thick cloth around the cap. Slowly turn cap counterclockwise until pressure begins to release. Step back while the pressure releases. When you are sure that all the pressure has been released, use the cloth to turn it counterclockwise and remove the cap. Slowly add prediluted engine coolant to the coolant reservoir until the coolant level is within the COLD FILL RANGE as listed on the reservoir. Reinstall the pressure relief cap. Start and run the engine at 2000 rpm for 2 minutes. Shut engine off, and remove the pressure relief cap as previously outlined. If required, add prediluted engine coolant to the coolant reservoir until the coolant level is within the COLD FILL RANGE as listed on the reservoir. 3. 4. 5. 6. 7. 8. 9. 46 Super Duty (TFA)
