Procedure
1. Open the drain tap (or unscrew the plug) at the bottom of the radiator.
2. When the flow of liquid weakens, unscrew the radiator cap.
3. Tighten the plugs and fill the cooling system with clean water. Start the engine and warm up the engine until the thermostat opens. Add water to the top of the neck. Stop the engine. Drain the water. Repeat the procedure until clean water flows.
4. Tighten the plugs with sealant. First add antifreeze and then water in the required proportion (you can also pour in a mixture of water and antifreeze). Warm up the engine and add a mixture of water and antifreeze to the required level. Close the radiator with the plug.
Attention! On 3.0L and 3.5L engines, before adding antifreeze, open the ventilation hole, near which there is a warning sign.
