Are you, Thinking of buying a Duramax?
We get calls every week from someone thinking about buying a Duramax, so we put together a video on the basics when looking for a Duramax.

 

Another good tip is to ask that the truck is cold when you arrive to look at it. I generally stress to the potential seller that when I get there to look at it, I would like to be the first person to start it that day. This gives me a chance to look at the upper radiator hose and make sure there is no pressure.
