<h3>Key features</h3><ul> <li>REPLACEMENT ENGINE COOLANT TEMPERATURE SENSOR : Engine Coolant Temperature Sensor is a sensor that is screwed into the engine's block or cylinder head. Common symptoms of a bad ECT sensor are overheating, hard starting conditions, poor idle, black smoke coming from the engine, Check Engine Light ON and the electric fans do not work properly. Be aware that coolant will gush out when removing the old plug so have the new sensor close and ready to attempt to reduce the amount of coolant loss.</li> <li>COMPATIBLE WITH BMW VEHICLES : 2011 BMW 1 Series M | 2008-2013 128i | 2008-2010 135i | 2014-2016 228i | 2013-2018 320i | 2001-2006 325Ci, 325i, 325xi | 1999-2000, 2007-2016 328i | 2009-2016 328i XDrive | 2007-2008 328xi, 335xi | 2001-2006 330Ci, 330i, 330xi | 2007-2010, 2014-2015 335i | 2014-2016 428i, 435i | 2004-2007 525i | 2006-2007 525xi | 2008-2016 528i | 2008 528xi, 535xi | 2004-2007 530i | 2006-2007 530xi | 2008-2016 535i | 2004-2005 545i | 2006-2016 550i coolant temperature sensor.</li> <li>REPLACES PART # : TS10270, 158-0792 Coolant Temperature Sensor.
