MAHLE 31319608 Engine Coolant Thermostat C - 90

The MAHLE BEHR 31319608 is an engine coolant thermostat with a 90-degree Celsius opening temperature, designed to maintain optimal engine operating temperature for efficient performance and reduced emissions. This thermostat regulates engine temperature with coolant, keeping the temperature as constant as possible to minimize wear and emissions.

Key Features:

• 90°C (194°F) opening temperature for precise thermal regulation
• Maintenance-free and durable expansion element design
• OE-quality construction from MAHLE BEHR, a leading OEM supplier
• Precision-engineered to meet original equipment specifications

The thermostat's expansion element contains wax that expands when heated to move the piston, allowing coolant flow; when temperature drops, it reduces in size and a spring returns the piston to its starting position. The thermostat blocks coolant flow to the radiator until the engine warms up, then opens to allow proper circulation, preventing both overheating and inefficient cold running conditions.
