The replacement of the antifreeze must be done only on the cold engine. First, you need to open the cork with the expansion pack. Move the large bucket down and remove the bottom tube from the heat sink. Wait for the old antifreeze. Check all the hoses of the cooling system for integrity.
The radiator needs a bottle of special equipment for rust and sediment removal. Whether to deactivate the deionized or demeralized water into the radiator and the tank top. Be sure to close all covers. After that, start the engine and let it warm up to the operating temperature, turn the stove on for the maximum.
Turn off the engine and let it cool. Remove the covers and drain the liquid. Then fill the system with normal water, seal the covers and re-enable the engine for 15 minutes. Re-let the engine cool and drain the water. Get a new antifreeze. Close the covers. Start the engine and check the antifreeze level (the lower mark is the weld beacup), if necessary.
