Cooling Testing: Operating Conditions and Temperature Goals 820048

Cooling testing conditions and temperature goals have been established based upon critical high ambient temperature field sites in the southwestern U.S. Mountain grade-climbing, level highway, build-up, city traffic, and idle tests are included. They are used for the evaluation and development of engine and transmission cooling systems and various underhood and underbody components and systems.
The procedures are designed for testing in a climatically-controlled wind tunnel, but are also suited, with appropriate adjustments, for road testing.
Substantial reductions in product weight and cost have been achieved while maintaining customer satisfaction by the application of these procedures which replaced previous unrealistically severe test conditions.
