Checking the coolant level
The coolant level should be checked regularly, approximately every 4 weeks and at least before each long trip. To top up the coolant, also in warm weather, use a mixture of antifreeze and distilled water.
Attention! In emergency situations, especially in summer, clean water can be poured into the cooling system. However, then, at the first opportunity, it is necessary to bring the concentration of antifreeze and anti-corrosion agent in the cooling liquid to the required level.
The coolant level when the engine is cold (coolant temperature approx. +20°C) should be only slightly above the KALT mark on the expansion tank (see arrow in illustration 10.0). If this level is lower, then liquid should be added to the tank.
Caution: To avoid engine damage, add large quantities of cold coolant only when the engine is cold.
Caution! When the engine is hot, place a thick cloth on the radiator filler cap before removing it to avoid being burned by hot coolant or steam. Remove the cap only when the coolant temperature is below +90°C.
1. Unscrew the expansion tank cap slightly to release excess pressure, then unscrew the cap completely and remove it.
If the fluid level drops significantly within a short period of time, inspect the system to check for leaks.
