The objective of this study was to develop, build and test a vehicular engine cooling module that is lower in air flow resistance and higher in both air-conditioning and engine cooling performance than the experimental vehicle's OE system. These improvements were accomplished using airflow management techniques. The vehicle under study was a 1989 four door sedan, with a 3.0 liter V-6 engine and automatic transmission. The developmental method consisted of four phases: (1) Understanding the effects of front end components on engine compartment airflow; (2) Improvement of airflow characteristics through shroud design; (3) Improvement in heat exchange capabilities and (4) Evaluation of air conditioning and engine cooling system performance on the road.
