For our latitudes, it is quite sufficient to have protection against freezing down to -30°C. Based on Ford concentrate, this corresponds to a 50% mixture. If the coolant level is adjusted from time to time by adding water, then the concentration of the antifreeze for cold temperatures may not be enough. Check the mixture with a hydrometer, antifreeze. As a rule of Faust, it is true: about 3/4 liter of coolant concentrate increases the protection against cold by about 10°C. In case of doubt, you can check the composition of the coolant at your Ford dealer.

Please note: Genuine coolant must not be mixed with other products – corrosion protection and compatibility with light metals are no longer guaranteed. In case of doubt, this may lead to a major overhaul of your Mondeo. If you still want to supplement the fluid with a product of unknown origin, it is better to replace the entire coolant. |

ORDER OF EXECUTION |
- Release the pressure in the system using the expansion tank cap. Be careful when the engine is hot: risk of scalding.
- Place a clean collecting container under the radiator and open the lower coolant hose clamp, disconnect the hose from the pipe or unscrew the drain screw of the reservoir.
- To allow the coolant to drain better, unscrew the expansion tank cap.
- Drain approximately 1-2 liters of coolant into the receiving container and close it.
- Install the lower hose, using a new clamp or drain screw with a new sealing ring if necessary.
- Fill the expansion tank with the required volume of coolant concentrate, then top up the remaining volume with the drained coolant.
- Don't forget to close the expansion tank.
Check: To check the correct coolant mixture ratio, you need a hydrometer (density meter). This device works with both a measuring pointer and - as shown in the figure - with a plunger. |

PRACTICAL ADVICE |
The engine is losing coolant
If your Mondeo loses large amounts of coolant while driving, do not add cold water under any circumstances: the hot engine may experience a "cold shock". In extreme cases, the cylinder block or cylinder head of the engine may be torn apart. A torn engine will prematurely turn into scrap metal, and a warped cylinder head will no longer seal the cylinders: the coolant will clearly leak out, mix with the engine oil, forming a lubricating emulsion. Let the Mondeo cool down thoroughly and add only water. In each case, the cause of the loss of coolant must be determined by a specialist. |
