What is the purpose of the oil pressure control valve on a Gen 5 oil/coolant module?

The purpose of the oil pressure control valve in a Gen 5 oil/coolant module is to manage excessive oil pressure by relieving it to the oil pan when it is not necessary. This function is crucial for maintaining optimal oil pressure throughout the engine's operation.

When the oil pressure exceeds a predetermined level, the valve opens and allows excess oil to flow back into the oil pan. This helps to prevent damage that could occur from excessively high oil pressure, such as seal failure or damage to engine components. It ensures that the oil system operates effectively while providing the necessary lubrication where it is needed, and helps maintain efficiency within the engine.

This functionality is particularly important in modern engines, which often have a more complex oiling system that can be subject to variable oil pressures. By effectively managing these pressures, the oil pressure control valve plays a vital role in the overall health and performance of the engine.
