Checking and topping up the coolant

Permanent check

PROCEDURE

Check the coolant level in the expansion tank only when the engine is cold. The cooling system in this case is not under pressure and the liquid expands «Fine». Even if the level is below the lower marking, do not add fluid, as the coolant expands automatically when the engine is warm. There must be enough space in the tank for such «excess» liquids. Thus, one should not be deceived by a supposedly low level. To top up, carefully open the cap. When the engine is hot, the reservoir is under pressure. Therefore, first lay the lid around with a thick rag. If you recklessly open the lid, then there is a danger of scalding - the coolant beats out of the tank with a hot key. Add coolant to the reservoir, the level should not rise above the upper mark. Small volumes of liquid can be safely topped up when the engine is warm. Replenishment of liquid: Since the liquid level in the compensation tank must exceed the "MIN" mark, it is necessary to replenish the tank with pre-mixed liquid. When opening the reservoir, pay attention to the formation of bubbles and oil sludge - this most often indicates a defective cylinder head gasket.

Ageless - Genuine Coolant

Ford requires the Mondeo to have its coolant changed after 10 years or 240,000 kilometers. Naturally, this only applies to genuine WSS-M97B44-D fluid (Motorcraft Super Plus 2000). When it comes time to replace, proceed as follows.
