Where is the engine coolant temperature sensor on my 2008 Malibu LTZ, with 2.4L Ecotec engine? I've checked online and can't seem to find a good video or guidance. I thought it would jump out at me once I removed the engine cover. No such luck. I would appreciate any help I can get.
Once you get the cover off, the sensor is located towards the back of the engine on the right side (as if you're sitting in the vehicle - passenger side for people in the States). I've clipped a couple of images from this video (very crappy quality, but it gets the point across). It is for a 2011 Malibu, but seeing as how it's the same 2.4L Ecotec engine, location and all should be about the same.
The silver thing at the bottom of the image looks to be an exhaust shroud, but I'm not sure.
Dude was nice enough to tell us you'd need a 19mm deep well socket to get to it. This image shows the sensor with the plug disconnected. This image would be if you rolled over the engine a little farther into the engine compartment from the first image. Hopefully you can make out where it's at.
