Another question from a new duramax owner. The cord to plug for the engine coolant heater (engine block heater? same thing??) is short and right now I am draping the cord over the edge of the body under the hood in one of those notches on the inside of the body panel. This means I have to open the hood everytime I want to plug the heater in. This is a 2006 Silverado LB7 engine. My old '96 Sierra 6.5 just had the cord hanging down in front and I accessed it through the left front wheel well. Is there a way of threading the cord down into the right front wheel well a way that won't damage anything and I don't have to open the hood?
