Engine and Radiator Flushing

Engine and Radiator Flushing

Special Tool(s):

Material:

1. WARNING: Never remove the pressure relief cap while the engine is operating or when the cooling system is hot. Failure to follow these instructions can result in damage to the cooling system or engine or personal injury. To avoid having scalding hot coolant or steam blow out of the degas bottle when removing the pressure relief cap, wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly. Step back while the pressure is released from the cooling system. When you are sure all the pressure has been released, turn and remove the pressure relief cap (still with a cloth).

Once pressure is released, remove the pressure relief cap/radiator cap.
2. Drain the cooling system.
3. Remove the coolant thermostat.
4. Install the coolant hose connection without the thermostat.

5. NOTE: Refer to the cooling system flusher manufacturer's operating instructions for specific vehicle hook-up.

Using an appropriate cooling system flusher, flush the engine and radiator.
Use Premium Cooling System Flush or equivalent meeting Ford specification ESR-M14P7-A. Always flush the cooling system with water thoroughly after using the VC-1 flush and prior to filling the cooling system with the same coolant that was present in the system. Do not mix coolant types.
6. Install the thermostat.
7. Backflush the heater core.
8. Fill and bleed the cooling system.
