STANDARD EQUIPMENT
AERO SHUTTERS
Aero shutters are designed to close when operating conditions
permit. The shutters are located on the front of the A/C condenser
under hood to divert airflow around the front of the truck reducing
wind drag and improves fuel economy. When the cooling system
requires more air flow the shutters automatically reopen, ensuring
proper air flow through the radiator.
NOTE: : Aero Shutters will remain open at speeds under 30mph.
TRANSMISSION OIL COOLER
FRONT
Transmission oil is pumped from the transmission through piping
to an oil to air heat exchanger in the upper portion of the air
conditioning condenser tuning and returns to the transmission.
The air conditioning condenser is located in front of the engine
coolant radiator as part of the Cooling Fan and Radiator Module
(CFRM) assembly.
ROUTING GROMMET
Provides pass through for small number of wires and is located at
the lower left side of the front of dash. Carefully remove or puncture
