MAHLE Engine Coolant Thermostat with O-Ring

The MAHLE engine coolant thermostat with O-ring helps your engine reach operating temperature quickly and hold it there. It regulates coolant flow between the engine and the radiator. A thermostat that works properly supports efficient combustion, steady cabin heat, and long engine life. This product line is also called a coolant thermostat or engine thermostat.

Key Features:

• Opens and closes at a calibrated temperature to control coolant flow and engine operating temperature
• Supplied with an O-ring for a leak-resistant seal at the thermostat housing
• Built by MAHLE, a well-known OE supplier of engine and thermal management components
• Designed as a direct-replacement part to restore proper cooling system performance
• Helps prevent overheating, and also helps prevent running too cold, which can hurt fuel economy and increase engine wear

Replace the thermostat when you service the cooling system, or whenever it sticks or responds slowly. Common signs of a failing thermostat include overheating, slow warm-up, temperature gauge swings, and weak heater output. Refill the system with the correct coolant and bleed out any air after installation.
