ECMs and Thermostats

Why in the world is the drain plug for the radiator on a 2010 Chevy Aveo LT located at the very bottom on the side. Not just in a annoying place but behind some A/C lines and sits right behind the core support. So after fitting your hand into space about three inches wide you then have to put a 13mm wrench on it to break it loose. Well after that struggle the radiator can be trained and the thermostat can be removed from its housing. Make sure to spray down the bolts on the housing. Hate when manufacturers connect aluminum parts to cast iron parts with aluminum bolts. Welcome to snap city! ECMs oh the good and hard to find ECMs. You figure they would be mounted inside the cab or another location where they wouldn't be exposed to the elements. But nope not on a 1191 Freightliner FLD. Right inside the frame is where you can find it, covered with dirt and grease. Along side labeling the sensors and outputs, finding the J1939 wires can be a challenge in the dirt and grease. But my team and I did.
