2. Check the level in the expansion tank; if the level is below the "Min" mark, top up to the "Max" mark using only the specified antifreeze/water mixture (Figure 2.1)If the expansion tank is empty, check the level in the radiator and top it up before opening the filter (Figure 2.2), then close the radiator cap and fill the expansion tank to the "Max" mark (photo).

2.2A. The coolant level must be checked and topped up if necessary in the expansion tank
2.2V. Add to the radiator if the expansion tank is empty
3. If frequent refueling is required, there is probably a leak in the system or the engine often overheats. Check all hoses and connector surfaces. If no leaks are found, check the system pressure, as there may be an internal leak. Check the engine oil level in this case, an internal coolant leak can cause the oil level in the pan to rise.
4. With the frequency given in Section "Maintenance" at the beginning of this manual, carefully inspect all hoses, hose clamps, and gaskets. Replace any suspect hoses and clamps if necessary.
5. Check all drive belts. Replace worn or damaged drive belts as necessary.
6. Change the coolant in the cooling system using fresh antifreeze.
