{"product_id":"m278-m157-v8-thermostat-103-c","title":"M278\/M157 V8 Thermostat (103°C)","description":"This unit includes the housing and seal and is rated at 103°C. It regulates the flow of hot engine coolant to the radiator for cooling, thereby maintaining the precise operating temperature required for Mercedes M278 and M157 V8 engines.\n\nThis thermostat is essential for preventing engine damage caused by overheating or under-operating temperatures. It directly replaces failed thermostats that may be stuck open, stuck closed, or unable to fully open or close. A thermostat stuck open will prevent the engine from reaching its optimal operating temperature, while a thermostat stuck closed will cause the engine to overheat. Therefore, it is recommended to replace this component if your vehicle has experienced any overheating issues to ensure proper system function.\n\nThis genuine Mercedes-Benz thermostat assembly is compatible with a wide range of models, including CL550 (2011-2014), CL63 AMG (2011-2014), CLS550 (2012-2018), CLS63 AMG (2012-2014), CLS63 AMG S (2014-2018), E550 (2012-2017), E63 AMG (2012-2015), E63 AMG S (2014-2016), G63 AMG (2013-2018), GL450 (2013-2016), GL63 AMG (2013-2019), GLE63 AMG S (2016-2019), GLS550 (2017-2019), GLS63 AMG (2017-2019), Maybach S550 (2017), ML550 (2012-2014), ML63 AMG (2012-2015), S550 (2012-2017), S63 AMG (2011-2017), SL550 (2013-2020), and SL63 AMG (2013-2019).","brand":"Mercedes-Benz","offers":[{"title":"Default Title","offer_id":52873009725752,"sku":"MB2782000615","price":467.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/m278-m157-v8-thermostat-103-c","provider":"MOTORMIA","version":"1.0","type":"link"}
