Note: Coolant is constantly circulated through the heater core, which improves engine cooling efficiency.
Refueling
Be sure to open the air bleed valves. Fill the system with coolant through the expansion tank opening.
Close the air bleed valves once liquid begins to flow out of them in a continuous stream.
Start the engine (2500 min⁻¹).
Add liquid to the top edge of the filler neck within approximately 4 minutes.
Close the expansion tank cap.
Removal air
Let the engine run for 20 minutes at 2500 rpm⁻¹, until the electric fan turns on (the specified time is necessary for automatic degassing of the coolant). Make sure that the fluid level in the reservoir is at the mark
Caution: Do not open one or more air bleed valves while the engine is running.
