5. Disconnect the heater supply hose from the engine.
6. Using a funnel, fill the cooling system through the supply hose until the coolant starts to trickle from the engine.
7. Reconnect the heater supply hose.
8. Refill the coolant expansion tank to the MAX mark (with the engine switched off).
9. Install the coolant expansion tank cap.
10. Install the ignition coil pack. For additional information, refer to «ENGINE IGNITION - 2.0L SPI»(ref-207754) .
11. Install the ignition coil bracket. For additional information, refer to «ENGINE IGNITION - 2.0L ZETEC»(ref-207753) .
12. Connect the mass air flow (MAF) sensor electrical connector.
13. Install the air cleaner outlet pipe.
14. Start the engine, maintain the engine speed at 2750 revolutions per minute (RPM) for two fan cycles.
15. Switch the engine off.
16. Check the cooling system for leaks.
17. Allow the engine to cool.
18. Fill the coolant expansion tank to the MAX mark.

Cooling System Flushing

MATERIAL SPECIFICATION

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-207748-S31865804662005120100000) . Remove the thermostat prior to pressure flushing. 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.
2. Remove the radiator. For additional information, refer to «RADIATOR - SVT»(ref-207748-S41988951292005120100000) , «RADIATOR»(ref-207748-S23161856432005120100000) , or «RADIATOR - 2.3L»(ref-207748-S07947526842005120100000) .
3. Backflush the radiator with the radiator in an upside down position with a high-pressure hose in the lower hose location and backflush.
4. Remove the thermostat. For additional information, refer to «THERMOSTAT - SVT»(ref-207748-S23626603972005120100000) , «THERMOSTAT - 2.0L ZETEC»(ref-207748-S33715092092005120100000) , «THERMOSTAT - 2.0L SPI»(ref-207748-S38671058382005120100000) or «THERMOSTAT HOUSING - 2.3L»(ref-207748-S09150378842005120100000) .
5. Backflush the engine. Position the high-pressure water hose into the engine through the engine return and backflush the engine. CAUTION: The heater core must be backflushed separately from the engine cooling system to make sure of correct backflush water flow direction through the heater core. All engine cooling system flushing and backflushing procedures must include a separate backflushing of the heater core or A/C system heater core after the flushing or backflushing of the engine cooling system. This will prevent the engine cooling system particles from clogging the heater core tubes and reducing (or preventing) coolant flow through the heater core.
6. Disconnect the heater outlet hose from the engine intake connector and install a garden hose (from a tap), with a male adapter into the end of the heater outlet hose. Secure with a hose clamp.
7. Connect a garden hose to the engine intake connector and secure with a hose clamp. Allow the open end to drain into a suitable container or drain.
8. Turn the water supply tap ON and OFF several times, so that the surge action will help to dislodge larger, stubborn particles from the heater core tubes. Allow water pressure to flow for approximately five minutes.
9. Remove the garden hose with the male adapter from the heater outlet hose. Remove the garden hose from the engine intake connector and reconnect the heater outlet hose onto the engine intake connector.
10. Fill the cooling system as described, using a 50/50 mixture of Ford cooling system fluid and water. For additional information, refer to «SPECIFICATIONS»(ref-207748-S31865804662005120100000) .
11. Test the system for correct heater operation within the engine cooling system conditions.
