Replacement of a cooling liquid spend after ten years of operation of the car or 240 000 km of run. This rule extends only for original mark М97В44-D (Мotorcaft Super Plus 2000). However it is regular, approximately at every third refuelling, supervise liquid level in a broad tank. Do it on the cold engine when in system of cooling there is no superfluous pressure.

Fig. 35. If level of a cooling liquid in a broad tank has fallen below a mark min add in a tank cooling liquid. Pay attention, whether is not present in a tank and an oil film

On the cold engine level of a cooling liquid should be not less the bottom level. At the working engine the cooling liquid extends, taking into account it the tank should have enough place. At нагретом the engine the cooling system is under pressure. A liquid add on the cold engine. On the hot engine, at opening of a cover of a broad tank, there is a danger to scald. Do not add a liquid above a maximum level. You can add a small amount of a liquid at нагретом the engine (a Fig. 35).
