Duramax

Duramax diesel engines power heavy-duty Chevrolet and GMC trucks, and they're built differently than gasoline engines. These engines handle towing, hauling, and sustained high loads that would overwhelm lighter powerplants. Understanding how a Duramax works—from its fuel injection system to its turbocharger and cooling demands—helps you maintain it properly and catch problems before they become expensive repairs.

The articles here cover the specific maintenance tasks Duramax owners face: how to change oil in an engine designed for diesel fuel, what intervals to follow, why these engines need different service than gas trucks, and how to spot signs of wear or damage. You'll learn what makes diesel oil different, how to handle the fuel system, and what to watch for during routine checks.
