“Hello everyone and welcome!” On this episode of engineering explained we see what it looks like to warm up an engine in temperatures below freezing. He uses a thermal camera to show what it looks like when you start a completely cold engine. In this demonstration, he uses a Subaru Crosstrek so it’s just a small 4 cylinder engine. It takes a few minutes for an engine to idle up to operating temps from 20 degrees and you can see what gets hot first we the thermal camera!
