I have no idea of the location, but I seriously doubt it is on the bottom left side. T-Stats are usually on the top side. Follow the top radiator hose back to the engine and it should be under neath where it attaches to the engine.

How to replace temperature sensor 2005 buick rainier

To get to it, you must remove the alternator and alternator bracket first. Bottom bolt on the bracket and alternator is difficult to get to. I find that using a ratcheting box end wrench is the easiest. You might as well replace the thermostat while you're in there, it's 2" below the actual sensor on the drivers side of the vehicle. Also removing the drivers side tire will make easier work of this job.
