1. Unscrew the expansion tank cap (see photo), place the container under the right side of the radiator.
2. On some vehicles, remove the mud deflector under the radiator. Attach a hose to the radiator drain cock nipple (see photo), which you lower into the vessel. Unscrew the tap and drain the liquid. There is no drain plug in the cylinder block. Therefore, liquid may remain in the cylinder block, which is replaced with water during flushing. When filling the system, check the density of the liquid, which must correspond to the required freezing point.

3. The cooling system is flushed with running water from a hose. Disconnect the upper and lower hoses from the radiator and flush the radiator and cylinder block with running water. The system is flushed until clean water flows from the hose. In case of heavy contamination, flush the radiator and cylinder block in the opposite direction. It is allowed to use special detergents.
4. The system is filled through the expansion tank. Bring the liquid level up to the KALT (or COLD) mark on the tank. When filling the cooling system with liquid, periodically remove air by squeezing the upper and lower radiator hoses.
5. Warm up the engine, stop it, and after the engine has cooled down, check the fluid level in the expansion tank. Add fluid if necessary.
