Watching A Frozen Engine Warm Up With A Thermal Camera

In this video we’re going to be cold starting the engine of my 2016 Subaru Crosstrek, and using a thermal camera we’re going to watch the engine heat up. The ambient temperature is about negative 6 degrees Celsius or about 22 degrees Fahrenheit. As far as metrics we’ll be monitoring, we’ve got overlays of the engine RPM, which will run higher when the engine first starts to help warm things up. We also have throttle position, the coolant and intake air temperatures, the temperature of where the thermal camera is centered, and a timestamp so we know how long the engine has been running.
