I work in the telcom industry and am not a mechanic. Our mechanic told us that there is nothing wrong with our derrick digger, a 2003 GM C8500 w/ caterpillar C7ACERT engine. The catch is that we were told to warm up the engine for 30 to 45 minutes before using the truck. It sounds like a joke, but they're dead serious. Has anyone heard of such a thing before, and what recommendations do you have for us users of the truck?
Thanks
