Attention. Check the cooling system for leaks.
Install a coolant bottle on the filler neck (4).

The coolant fill bottle must be filled to the 1 liter mark to properly bleed the system.
Start the engine.
Set the engine to run at 1500 to 2000 rpm until the end of the second cooling cycle (turning on/off the electric fan), maintaining a level of 1 liter in the cylinder for filling the coolant. Stop the engine.
Remove the coolant fill bottle (4).
Quickly screw the cap onto the tank to remove air bubbles. If necessary, bring the coolant level to the maximum mark (engine must be cold).
