Where is the Coolant Temperature Sensor located on the 2006 Chevy Malibu, V6 3.5L The temperature gauge stopped working and the car is having a hard time starting without giving the car gas, and from what I've read, this is the best place to start.
Do you

Either everyone who has responded to you is assuming that they know your particular model and year of Malibu, or they just don t know what they are talking about. A more accurate answer is that it depends on the aforementioned variables. For instance, on a 2006 Chevy Malibu MAXX - LTZ, the sensor is ON THE LEFT side of the block.
