About this episode

The episode discusses the importance of proper coolant maintenance in diesel engines and common mistakes truck owners make regarding their cooling systems.

Modern diesel engines generate a lot of heat, and keeping that heat under control puts a huge demand on the cooling system. But how often should you actually change your coolant, and what happens when you leave it in too long? Rislone joins us to talk about diesel cooling systems, proper coolant maintenance, and some of the common mistakes truck owners make. We discuss corrosion and contaminants that can build up over time, how coolant condition can affect heat transfer, best practices when changing coolant, and why maintaining the cooling system is so important on modern Cummins, Duramax, and Power Stroke engines.
