Material

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 Premium Gold Engine Coolant. Mixing coolant types degrades the corrosion protection of Motorcraft Premium Gold Engine Coolant.

Note. Stop-leak style pellets/products must not be used as an additive in this engine cooling system. The addition of stop-leak style pellets/products may 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.

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to «JACKING AND LIFTING»(ref-293448) article.
2. Release the pressure in the cooling system by slowly turning the pressure relief cap one half to one turn counterclockwise to the first stop on the filler neck. When the pressure has been released, remove the pressure relief cap.
3. Remove the front splash shield.
4. Place a suitable container below the radiator draincock. Drain the coolant.
5. Close the radiator draincock and install the front splash shield when finished.

Cooling System Flushing

Material

1. 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»(ref-293488-S26227004532008080700000) . 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 a cooling system flusher. Dispose of old coolant and flushing water contaminated with antifreeze and cleaning chemicals in accordance with local, state or federal laws.
2. Drain the cooling system. For additional information, refer to «Cooling System Draining, Filling and Bleeding»(ref-293488-S26451391862008080700000) .
3. Remove the radiator. For additional information, refer to «Radiator»(ref-293488-S23663106672008080700000) .
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»(ref-293488-S04790124312008080700000) .
6. Backflush the engine. Position the high-pressure water hose into the engine through the engine return and backflush the engine.
7. Fill the cooling system. For additional information, refer to «Cooling System Draining, Filling and Bleeding»(ref-293488-S26451391862008080700000) .
