This part fits in the engine cooling / oil cooler circuit. It is used as a control and regulating valve for the oil cooler coolant flow, helping manage the temperature relationship between the engine coolant system and engine oil cooler.

Functions
• Regulates coolant flow through the oil cooler circuit
• Helps control engine oil temperature during operation
• Supports correct thermal management of the engine and oil cooling system
• Helps the engine reach and maintain the correct operating temperature
• Assists with efficient cooling under load and warmer driving conditions
• Provides factory-correct control valve operation
• Helps maintain OE Porsche cooling system performance and reliability.

The oil cooler control and regulating unit is exposed to constant heat cycles, coolant flow and pressure changes. Over time, the valve or thermostat mechanism can stick, leak, fail internally or stop regulating flow correctly. A faulty unit may affect oil temperature control, cooling efficiency or engine warm-up behaviour. Replacing it with a Genuine Porsche OE control and regulating unit helps restore correct cooling system regulation and protects the engine by maintaining the intended oil and coolant temperature balance.

When to replace
•   If the oil cooler control valve is leaking
•   If there are fault codes or symptoms linked to coolant/oil temperature regulation
•   If engine oil temperature is unstable or higher than expected
•   If the engine is slow to warm up or cooling regulation is poor

•   During oil cooler, coolant thermostat or cooling system repairs
•   If the original unit is cracked, damaged or seized
•   When replacing earlier superseded versions of the component.
