Draining

Note. The coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated, it must be recycled or disposed of correctly. Using contaminated coolant may result in damage to the engine or cooling system components.

Note. The engine cooling system is filled with Motorcraft® Specialty Orange Engine Coolant. Mixing coolant types degrades the corrosion protection of the coolant. Do not mix coolant types. Failure to follow these instructions may result in engine or cooling system damage.

Note. Always fill the cooling system with the manufacturer's specified coolant. Chemically flush the cooling system if a non-specified coolant has been used. Refer to COOLING SYSTEM FLUSHING in this service information. Failure to follow these instructions may damage the engine or cooling system.

Note. During normal vehicle operation, Motorcraft® Specialty Orange Engine Coolant may change color from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color change does not indicate the engine coolant has degraded nor does it require the engine coolant to be drained, the system to be flushed, or the engine coolant to be replaced.

Note. Do not use stop-leak style pellets/products as an additive in this engine cooling system. The addition of stop-leak style pellets/products can clog or damage the cooling system resulting in degraded cooling system performance and/or failure.

Note. Less than 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.

Scheme 66

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to «JACKING & LIFTING»(ref-494560) .
2. Release the pressure in the cooling system by slowly turning the pressure relief cap one-half turn counterclockwise. When the pressure is released, remove the pressure relief cap.
3. Remove the 3 push-pins, the 7 screws and the radiator splash shield.
4. Place a suitable container below the radiator draincock. Open the draincock and allow to drain. Close the draincock after draining.

Scheme 67

1. Install the radiator splash shield, the 7 screws and the 3 push-pins.
2. Install the vacuum cooling system filler and follow the manufacturer's instructions to fill and bleed the cooling system. Recommended coolant concentration is 50/50 engine coolant to distilled water. For extremely cold climates (less than -37°C [-34°F]): It may be necessary to increase the coolant concentration above 50%. NEVER increase the coolant concentration above 60%. Maximum coolant concentration is 60/40 for cold weather areas. A coolant concentration of 60% provides freeze point protection down to -50°C (-58°F). Engine coolant concentration above 60% will decrease the overheat protection characteristics of the engine coolant and may damage the engine. For extremely hot climates: It is still necessary to maintain the coolant concentration above 40%. NEVER decrease the coolant concentration below 40%. Minimum coolant concentration is 40/60 for warm weather areas. A coolant concentration of 40% provides freeze point protection down to -26°C (-15°F). Engine coolant concentration below 40% will decrease the corrosion and freeze protection characteristics of the engine coolant and may damage the engine. Vehicles driven year-round in non-extreme climates should use a 50/50 mixture of engine coolant and distilled water for optimum cooling system and engine protection.

Cooling System Flushing

MATERIAL SPECIFICATIONS

Note. To remove rust, sludge and other foreign material from the cooling system, use cooling system flush that is safe for use with aluminum radiators. For additional information, refer to SPECIFICATIONS . This cleaning restores cooling system efficiency and helps prevent overheating. A pulsating or reversed direction of flushing water will loosen sediment more quickly than a steady flow in the normal coolant flow direction. In severe cases where cleaning solvents will not clean the cooling system efficiently, it will be necessary to use the pressure flushing method using cooling system flusher. Dispose of old coolant and flushing water contaminated with antifreeze and cleaning chemicals in accordance with local, state or federal laws.

1. Add Motorcraft® Premium Cooling System Flush to the cooling system and follow the directions on the package.
2. Drain the cooling system. For additional information, refer to «COOLING SYSTEM DRAINING, FILLING AND BLEEDING»(ref-494611-S15464405062012081400000) in this service information.
3. Remove the radiator. For additional information, refer to «RADIATOR - 2.0L GTDI»(ref-494611-S03327403602012081400000) or «RADIATOR - 3.5L, 3.7L»(ref-494611-S32759719552012081400000) in this service information.
4. Backflush the radiator with the radiator in an upside-down position with a high-pressure hose in the lower hose location and backflush
5. Remove the thermostat. For additional information, refer to «THERMOSTAT HOUSING - 2.0L GTDI»(ref-494611-S12737825922012081400000) or «THERMOSTAT - 3.5L, 3.7L»(ref-494611-S05779607372012081400000) in this service information.
6. For 3.5L and 3.7L engines, install the coolant inlet connection without the thermostat. Tighten the bolts to 10 Nm (89 lb-in).
7. Backflush the engine. Position the high-pressure water hose into the engine through the upper radiator hose and backflush the engine.
8. Install the thermostat. For additional information, refer to «THERMOSTAT HOUSING - 2.0L GTDI»(ref-494611-S12737825922012081400000) or «THERMOSTAT - 3.5L, 3.7L»(ref-494611-S05779607372012081400000) in this service information.
9. Install the radiator. For additional information, refer to «RADIATOR - 2.0L GTDI»(ref-494611-S03327403602012081400000) or «RADIATOR - 3.5L, 3.7L»(ref-494611-S32759719552012081400000) in this service information.
