Engine Cooling - Cooling System Backflushing Transit/Tourneo Connect 2002.5 (06/2002-)
General Procedures

CAUTION:
CAUTION:The heater core must be backflushed separately from the engine cooling system to make sure 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 to prevent the engine cooling system particles from clogging the heater core tubes and reducing (or preventing) coolant flow through the heater core.
  1. 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.
  1. 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.
  1. 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.
  1. 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.
  1. Fill the cooling system as described, using a 50/50 mixture of Ford cooling system fluid and water.
    For additional information, refer to Specifications in this section.
  1. Test the system for correct heater operation within the engine cooling system conditions.
