Cold weather can quietly do serious damage to diesel engines if drivers don’t understand what’s happening under the hood. In this episode of Maintenance Matters on Road Gang Radio, Kevin Lindsey of TravelCenters of America joins Jimmy Mac to break down what winter really does to your engine — from cold starts and oil viscosity to electrical connections, batteries, belts, and air intake issues.

Kevin explains why diesel engines need extra care in freezing temperatures, how contraction and windchill effects inside the engine can create hidden problems, and what drivers should not do when starting a truck on a cold morning. The conversation also covers preventative maintenance strategies, battery testing, belt tension, lubrication, and why taking your time during startup can reduce long-term wear.

If you drive, manage, or maintain diesel equipment in winter conditions, this episode offers practical insight to help you mitigate damage, extend component life, and stay on the road during the coldest months of the year.
