{"product_id":"thermostat-and-housing-assembly-2","title":"Thermostat and Housing Assembly","description":"When the engine is cold, the thermostat remains closed, restricting coolant flow and allowing the engine to warm up more quickly. Once the engine reaches its operating temperature, the thermostat opens, facilitating normal coolant circulation to prevent overheating.\n\nThis component is critical for preventing two common failure modes: being stuck open, which leads to an engine not reaching operating temperature, poor fuel economy, and potential catalytic converter damage; or being stuck closed, which restricts coolant flow and can cause severe engine overheating and damage. Symptoms of a faulty thermostat include an overheating engine, an engine that never reaches optimal running temperature, or a radiator fan that fails to engage.\n\nThis thermostat assembly includes the necessary housing and gasket for a complete installation. It is designed as a direct replacement part for the specified Audi and Volkswagen models.\n\nThis thermostat fits a range of Audi and Volkswagen vehicles, including:\n- Audi A6 Quattro (Base Sedan, 4.2L V8) from 2007-2011\n- Audi A8 Quattro (Base Sedan and L Sedan, 4.2L V8) from 2007-2010\n- Audi Q7 (Base, Premium Sport Utility, 4.2L V8) from 2007-2010\n- Audi S6 (Base Sedan, 5.2L V10) from 2007-2011\n- Audi S8 (Base Sedan, 5.2L V10) from 2007-2009\n- Volkswagen Touareg (Base Sport Utility, 4.2L V8) from 2007-2009","brand":"Mahle\/Behr","offers":[{"title":"Default Title","offer_id":52687224701240,"sku":"079-121-115-BK","price":82.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662155341.jpg?v=1784881587","url":"https:\/\/store.motormia.co\/products\/thermostat-and-housing-assembly-2","provider":"MOTORMIA","version":"1.0","type":"link"}
