APUs provide driver comfort without engines idling
Hypothetically, let’s say you’re manager of a trucking company in Vermont. Capitalizing on the insatiable demand for maple syrup that rages throughout the southeast United States, you maintain a lucrative seasonal business hauling freshly packaged bottles of the sweet treat to Atlanta, Ga., and returning with rolls of carpeting.

Some while back, Bob Deierlein, our long-time research editor, wrote an article on cooling systems. In that article, he referenced some maintenance records of a large over-the-road fleet, which indicated that a substantial percentage of the fleet’s engine problems could be traced back to the condition of the truck’s cooling system. We published that article more than 20 years ago.
