14) Start the engine and run at idle speed for approximately 1 minute.
15) Bring the engine speed to 2000 rpm for approximately 15 seconds, then allow the engine to return to
idle speed.
16) If necessary, top up to the MIN level indicated on the expansion tank.
17) Warm the engine up by running at 2000 rpm until the thermostat valve opens/cooling fans activate
(water temperature approx. 90°C), then allow the engine to return to idle speed.
18) Top up if necessary.
19) Open the heater circuit (TGK valve_1 open and idle speed pump running) by setting the maximum
temperature for one "zone" only of the air conditioning system.
20) Bring the engine speed to 2000 rpm for approximately 1 minute, then run at idle speed for 30
seconds.
21) Invert the temperature settings for the two air conditioning system "zones" (TGK valve_2 open and
TGK valve_1 closed).
22) Bring the engine speed to 2000 rpm for approximately 1 minute, then run at idle speed for 30
seconds.
23) Close the heater circuit and top up if necessary.
24) Repeat the procedure twice from step 19 to step 23.
25) Open the heater circuit, setting the maximum temperature for both "zones" of the air conditioning
system (TGK valve_1 and TGK valve_2 open); bring the engine speed to 2000 rpm for approximately 1
minute, then run at idle speed for 30 seconds.
26) Bring the engine speed to 2000 rpm, close the heater circuit (TGK valve_1 and TGK valve_2 closed
and idle speed pump not running), then let the engine return to idle speed after 1 minute.
27) Switch off the engine and allow it to cool (water temperature 40-45°C) for approximately 1h 30 min.
