CAUTION:
You can be burned if you spill coolant on hot

When the coolant in the coolant recovery tank is at or
above the COLD mark, start your vehicle.
If the overheat warning continues, there's one more

Wait for the cooling system and radiator pressure
cap to cool if you ever have to turn the pressure cap.
