It’s Getting Hot Out There. Is Your Fleet Ready?

Maintaining a fleet of semi-trucks is challenging, especially during the hot summer months when high temps do a real number on vehicles and drivers. Here are a handful of practical tips to ensure your fleet remains healthy and operational throughout the summer, regardless of how hot it gets. 

Practice Regular Cooling System Maintenance

Inspect and Maintain Radiators: Heat is the number one enemy of engines, and healthy radiators keep engines cool. Do what you need to do to make sure radiators are free of debris and functioning properly. Regularly flush the cooling system and check for any leaks or damage.

Check Coolant Levels: Coolant levels should be checked frequently. Low coolant can lead to overheating, which can cause severe engine damage. Use a coolant mixture suitable for high temperatures and check the concentration to ensure it provides adequate protection.

Monitor Tire Health

Check Tire Pressure: Hot weather causes tire pressure to increase, leading to blowouts. Regularly check and adjust tire pressure according to the manufacturer’s recommendations. Over-inflated or under-inflated tires can be dangerous, plus they don’t do fuel efficiency numbers any favors.

Inspect for Wear and Tear: Summer heat can exacerbate tire wear. Inspect tires for signs of damage, such as cracks, bulges, or excessive tread wear, and replace tires accordingly to prevent accidents.

Keep the Air Conditioning Running

Regular AC Maintenance: Drivers need to stay cool and comfortable to remain alert and safe. Give all the air conditioning systems in your fleet a once over to make sure they’re in good working order and keeping things cool. Regularly check the refrigerant levels and have systems serviced if necessary.

Cabin Insulation: Proper insulation in the cab can help maintain a comfortable temperature, reducing the workload on the AC system. Check the seals around doors and windows and repair any gaps to prevent hot air from entering the cab.

Perform Electrical System Checks

Inspect Battery Health: High temperatures can reduce battery life and performance. Regularly check the battery terminals for corrosion and ensure they are tightly connected. Test the battery’s charge and replace it if necessary to avoid getting stranded in a hot truck.

Monitor Electrical Components: Heat can affect other electrical components, such as alternators and starters as well. Regular inspections will help identify and address any issues before they lead to problems.

Watch Lubrication and Fluid Levels

Engine Oil: Hot weather can increase the rate at which engine oil breaks down. Check and change the engine oil regularly and use a high-quality oil that can withstand higher temperatures.

Transmission and Brake Fluids: Ensure all fluids are at the appropriate levels and in good condition. Heat can cause fluid degradation, leading to poor performance and potential system failures, so keep a close eye on all of it during hot summer months. 

Make Preventative Measures a Habit

Regular Inspections: Implement a schedule of regular inspections and maintenance checks. Proactive maintenance can identify potential problems before they become costly repairs.

Driver Training: Educate drivers on the importance of regular checks and what red flags to look for during the summer. Encourage them to report any issues immediately so they can be addressed promptly.

Fleet Management Software: Utilize fleet management software to keep track of maintenance schedules, repairs, and inspections. This can help ensure nothing is overlooked and that your fleet remains in top condition.

By following these tips, you can keep your fleet of semi-trucks healthy and operational during the hot summer months. Maintaining your vehicles protects your investment and safeguards your team of drivers and the efficiency of your operations. If you’re considering expanding your fleet or you find vehicles that are not up to the demands of summer driving, there are always fleet trucks for sale that meet high standards for durability and performance, even in extreme conditions.
