The Calorstat TE6499.97J is a precision-engineered engine coolant thermostat designed to regulate and maintain optimal engine temperature for peak performance and longevity. Manufactured by Calorstat by Vernet, a trusted name in automotive thermal management, this thermostat features a 97°C (207°F) opening temperature to ensure your engine reaches its ideal operating range quickly and efficiently.

Key Features:

• 97°C (207°F) opening temperature for precise thermal control
• OEM-quality construction meeting strict manufacturing standards
• Direct replacement for BMW part numbers 11531436823, 11531437040, and 11537509227
• Wax-element design for reliable, consistent operation
• Helps prevent excessive fuel consumption and reduces emissions
• Extends engine life cycle by maintaining proper operating temperatures

The thermostat plays a critical role in your vehicle's cooling system by controlling coolant flow to the radiator. When the engine is cold, the thermostat remains closed to allow rapid warm-up. Once the coolant reaches 97°C, the wax element expands to open the valve, allowing coolant to circulate through the radiator for optimal temperature regulation year-round, regardless of outside conditions.
