Keep Your Fleet Moving: The Importance of Block Heaters in Heavy-Duty Trucks
As winter tightens its grip on the Northeast, fleet managers and truck operators face a familiar challenge: keeping diesel engines running smoothly in freezing temperatures. At Kenworth Northeast, we know that uptime is everything—and one of the most effective tools for cold-weather reliability is the humble block heater.
Why Block Heaters Matter
Diesel engines require significantly higher cylinder temperatures to ignite fuel compared to gasoline engines. In cold weather, this can make starting a diesel truck difficult, especially after it’s been parked overnight. A block heater warms the engine coolant and, in some cases, the oil, helping the engine reach optimal starting temperature faster and more reliably.
Benefits of Using Block Heaters
- Improved Cold Starts: Reduce wear and tear on your starter and battery by making cold starts easier.
- Fuel Efficiency: A warm engine reaches operating temperature faster, improving fuel economy and reducing idling time.
- Reduced Emissions: Cold starts can lead to incomplete combustion and higher emissions. Block heaters help mitigate this.
- Extended Engine Life: Less strain during startup means less long-term damage to engine components.
Best Practices
- Use a Timer: Plugging in your block heater 2–4 hours before starting your truck is usually sufficient. Timers help save energy and reduce costs.
- Check Connections: Inspect cords and plugs for wear or damage before each use.
- Pair with Anti-Gel Additives: Diesel fuel can gel in extreme cold. Use additives like Diesel 911 to keep fuel flowing freely.
