Open sealing cap. Set heater control to maximum temperature.
Set blower to low level. This opens the heating valves and sets the
auxiliary water pump in operation. Run engine and briefly press
accelerator pedal three to four times (approx. 4500 to 5000 rpm)
to flush engine cooling circuit. In doing so, do not run engine for
longer than approx. 30 seconds; otherwise coolant will heat up
and expand. If the coolant level drops in the expansion tank during
this operation, top up expansion tank with coolant up to edge.
Screw on sealing cap and warm up engine until thermostat opens.
