71°C Engine Coolant Thermostat

The Wahler 4249.71D is an OEM quality engine coolant thermostat, manufactured in Germany, designed to regulate your vehicle's engine temperature. It opens at 71°C and includes an aluminum housing and gasket. This thermostat plays a crucial role in the cooling system. When the engine is cold, the thermostat remains closed, restricting coolant flow and allowing the engine to reach its optimal operating temperature more quickly. Once the coolant reaches the thermostat's opening temperature, it opens to allow normal coolant circulation, preventing overheating and maintaining consistent engine performance. Wahler is a leading OEM manufacturer of thermal solutions for various automotive brands, including Porsche. Their replacement parts are identical to the original equipment, ensuring the same quality, service life, and operational reliability. This specific thermostat is designed for a range of Porsche Boxster, 911, and Cayman models, with detailed fitment information available for specific year and engine configurations.
