What feature does the Gen 5 oil/coolant module have that the GHG17 does not?

The Gen 5 oil/coolant module incorporates an oil pressure control valve, which is a significant advancement over the GHG17 design. This feature allows for improved management of oil flow under varying conditions, enhancing engine efficiency and performance. The oil pressure control valve helps maintain optimal pressure levels, which is critical for ensuring adequate lubrication of engine components and for regulating the temperature of the oil. This not only extends the longevity of the engine but also contributes to more efficient operation by preventing both over-pressurization and under-lubrication scenarios.

In contrast, the other options—including an oil temperature sensor, a coolant pressure sensor, and a bypass valve—while important for engine management, do not specifically characterize the Gen 5 module as distinguishing from the GHG17. These features may be present in both designs or serve different functions that do not directly enhance the control of oil pressure in the same way the oil pressure control valve does.

By integrating the oil pressure control valve, the Gen 5 design addresses some of the limitations of the previous generations, leading to better overall engine performance.
