Genuine BMW 11-42-7-573-051 Engine Oil Thermostat

The Genuine BMW 11-42-7-573-051 Engine Oil Thermostat is an OE-quality replacement component designed to regulate engine oil temperature for optimal performance and longevity. This thermostat maintains ideal oil viscosity by controlling coolant flow through the oil cooler, ensuring proper lubrication across all operating conditions.

Key Features:

• Genuine BMW OEM part for guaranteed fitment and quality
• Regulates oil temperature to maintain optimal viscosity
• Controls coolant flow through the engine oil cooler
• Prevents overcooling during warm-up and overheating under load
• Precision-engineered to OE specifications
• Direct replacement for worn or failed original thermostat

This engine oil thermostat is a critical component in BMW's engine cooling system, working in conjunction with the oil cooler to maintain proper oil temperature. When oil temperature is too low, the thermostat restricts coolant flow to allow faster warm-up. When oil temperature rises under heavy load or high ambient temperatures, the thermostat opens to increase coolant flow and prevent overheating. Regular replacement ensures consistent engine protection and performance.
