Genuine 059115201B Engine Oil Thermostat OEM VAG Oil Temperature Regulator

The Genuine 059 115 201 B is an Original Equipment Manufacturer (OEM) engine oil thermostat designed to factory specifications for Volkswagen Audi Group (VAG) vehicles. Also known as an oil temperature regulator or oil cooler thermostat, this component plays a critical role in engine lubrication system management by controlling the flow of oil through the oil cooler based on operating temperature.

When engine oil is cold, the thermostat bypasses the oil cooler, allowing the oil to reach optimal operating temperature quickly. Once the oil reaches the designed threshold temperature, the thermostat opens and routes oil through the cooler to prevent overheating and maintain consistent viscosity. This protects critical engine components and extends engine life.
