7.11 COLD WEATHER OPERATION
For cold weather operation, cowl inlet plates and an oil
cooler plate may be installed to restrict airflow to the
engine. This will increase engine oil temperatures when
operating in colder climates. These plates must be
removed when ambient temperatures exceed 40°F OAT.
See SL0003 for Installation.
