Resist winter — protection from frost down to -30°C (Focus Turnier 1)

Frost protection down to -30°C is quite sufficient in our country. This corresponds to approximately 50% mixture based on Ford concentrate. But if you periodically equalized the liquid level in between by adding water, then perhaps the concentration of antifreeze will no longer be sufficient for low temperatures. Check the concentration of the mixture with a hydrometer. The basic rule: adding about ¼ l of cooling concentrate increases frost protection by approximately 10°C. In case of doubt, ask your Ford dealer to re-prepare the coolant.

Be careful: do not mix the original coolant with other products - in this case, anti-corrosion protection and resistance of light metals to the coolant will not be ensured. In extreme cases, this will lead to a major overhaul of your Focus, i.e. if you want to top up the fluid, and the specification of the new product you are adding does not correspond to Ford's instructions, it is better to replace the coolant completely.

Stages of work

First, release the pressure in the system through the expansion tank shut-off cap. Be careful: if the engine is hot, there is a risk of scalding.

Place a clean container under the radiator and remove the lower coolant hose clamp or drain plug. Remove the coolant hose from the pipe.

To help the coolant drain better, remove the cap from the expansion tank. Drain approximately 1-2 liters of coolant, cover the receiving container.

Install the lower coolant hose (use a new clamp if necessary). Tighten the screw plug.

Pour the required amount of coolant concentrate into the expansion tank. Fill the remaining amount with the drained coolant and close the expansion tank.
