What does Generation 5 oil/coolant module lack in design?

The Generation 5 oil/coolant module is notable for its streamlined design, aiming to enhance efficiency and reduce complexity compared to earlier designs. One key characteristic of this design is the lack of an external crossover pipe.

In older oil/coolant modules, an external crossover pipe was often utilized to facilitate the transfer of oil and coolant for better thermal management. The removal of this component in the Generation 5 design means that it can achieve many of the same temperature regulation goals without the additional part, which helps reduce potential leak points and overall system weight. This design choice aligns with advancements in engine management and cooling strategies that prioritize integrated and compact solutions.

The absence of the external crossover pipe reflects a shift toward more advanced thermal management systems, where the integration within the module allows for improved performance and reliability without the need for extra external components.
