Attention. The coolant must be drained on a cold engine.
Unscrew the tank cap to remove air bubbles.
Open bleeder plugs (1), located on the coolant outlet block and heater tube.
Note. Put a piece of hose on the drain hole so that the liquid flowing from the system does not splash.
Disconnect the bottom hose (2) from the radiator.
Drain the coolant from the engine by removing the plug (3), located under the rigid tube from the coolant pump to the coolant outlet assembly (use extension, universal joint and 8.0 mm square socket if necessary). Close the drain hole with a plug.
