Note. The coolant constantly circulates through the heater core, thereby increasing the efficiency of engine cooling.
Refueling
Be sure to open the air bleed valves. Fill the system with coolant through the expansion tank opening.
Close the bleed valves when liquid begins to flow through them in a continuous stream.
Start the engine (2500 min-1).
Add liquid to the level of the upper edge of the neck for about 4 minutes.
Close the cap of the expansion tank.
Air removal
Let the engine run for 20 minutes at 2500 minutes before turning on the electric fan (the specified time is required for automatic degassing of the coolant). Make sure. that the liquid level in the tank is at the mark
Attention! Do not open one or more valves (ov) to bleed air while the engine is running.
Close the expansion tank cap when the engine is hot.
K4M and F4P engines
The location of the bleed valve on the thermostat block is shown in the figure.
