Coolant replacement (Power unit / Cooling system / Ford Mondeo 3 2000-2007)

PROCEDURE

Release the system pressure using the expansion tank cap. Be careful if the engine is hot: danger of scalding.
Position a clean receptacle under the radiator and open the lower coolant hose clamp or rear radiator reservoir drain screw.
To make the coolant drain better, unscrew the cap on the expansion tank. Drain the liquid and close the receiving container.
Mount the lower hose - while using a new mounting clamp. If the drain screw has been unscrewed, then a new sealing ring must be used here.
Top up the expansion tank with the prescribed coolant, then supplement the residual volume to about two millimeters below the upper mark with as little-known tap water as possible so that air bubbles no longer appear.
Start the engine and set the average speed. The engine should run until the thermostat opens. Top up with low-lime tap water if necessary. Make sure that the level in the tank remains constant when the engine is heated to operating temperature.
Screw on the locking cap and test drive. During this, your Mondeo will self-ventilate.
After a test drive, carefully open the expansion tank cap and run the engine at medium speed until the cooling fan comes on.
If required, add coolant up to the upper marking of the tank with mild lime tap water.
Don't forget to close the expansion tank.
