On this episode of Tech Talk with TMC on Road Gang Radio, guest host Robert Braswell, Executive Director of the ATA Technology & Maintenance Council (TMC), is joined by longtime TMC contributor and Silver Spark Plug recipient Derry Stewart of DWS Fleet Management for an in-depth discussion on cold weather truck operation and maintenance.

With extreme cold impacting much of the country, Robert and Derry break down the critical systems that fail first in winter and what drivers, owner-operators, and fleets can do to stay moving and stay safe. From batteries and fuel to winterfronts, cooling systems, and brakes, this episode focuses on preventive maintenance—not roadside reactions.

Topics include:

Why winter breakdowns are often caused by summer damage

Battery maintenance, voltage loss, and electrical connections

Why batteries matter more than oil in cold weather

Fuel condensation, water contamination, and filter freeze-ups

When and how to blend diesel with kerosene

Additives, isopropyl alcohol, and moisture control

Fuel heaters: in-tank, coolant-based, and electrical options

Winterfront design mistakes that damage cooling systems

Thermostats, radiator caps, and engine operating temperature

Coolant ratios and freeze protection best practices

Air system freezing, brake drag, and alcohol use

What to carry in the cab for cold-weather emergencies

This episode emphasizes planning ahead, disciplined maintenance, and understanding how cold weather truly affects modern trucks. A must-listen for anyone operating in freezing conditions.
