How Different Weather Affects Truck Engines

The temperatures are dropping, and warm weather seems far away. But whether you like colder or hotter weather, there are risks to both when making long trips in your commercial truck.

Let’s discuss how different weather affects truck engines to ensure you know what to do in unexpected engine situations.

Slows Engine Oil Flow

When the weather reaches approximately 20 degrees below 0, the engine oil thickens more than usual, making it more challenging for the pump to circulate.

Try checking with your mechanic to determine which type of oil is best for your truck engine. Some may suggest that synthetic oils can improve performance. They might give you tips for how to know if your diesel engine needs repairs.

Tire Deflation/Blowouts

Both hot and cold conditions can affect how your tires operate on the road. In colder weather, your tires tend to contract and lose pressure, making them easier to deflate if left untreated. Tires can blow out or catch fire during the hotter months if they’re over- or under-inflated.

Pre- and post-trip inspections can help you determine which actions to take to ensure the components on the truck don’t impact its engine.

Belts Might Crack

Although hot weather can negatively affect your truck’s engine, cold weather might be the most significant culprit in impacting the vehicle’s operation.

In colder weather, serpentine belts become rigid and harder to bend during movement, making them susceptible to cracking.

Your mechanic can perform a thorough engine inspection to ensure your belts are in good condition before and after your trip.

Reduces Battery Power

Whether you’re driving in hot or cold weather, harsh temperatures can strain your battery power, affecting performance and startup ability.

Colder temperatures tend to slow down the chemical reactions needed to build battery power, while hot temperatures increase the reaction’s speeds.

Due to thicker oil, your engine requires more power to operate, making the battery power easy to decrease in quality. Talk to your mechanic or go online to learn how to troubleshoot engine problems, so you know what to do on your trip.

You might consider purchasing a battery heater and reducing draining features like the radio cab lights.

Now that you understand how different weather affects truck engines, you can better manage your truck during long trips and prepare more efficiently.
