Air Baffles and Seals
WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
The cooling system uses deflectors, air baffles and air seals in order to increase system cooling. Deflectors are installed under the vehicle in order to redirect airflow through the radiator which increases cooling. Air baffles are also used in order to direct airflow into the radiator and increase cooling. Air seals prevent air from bypassing the radiator and the A/C condenser. Air seals also prevent recirculation of the air for better hot-weather cooling and A/C condenser performance.
