Beat the Heat: Pro Tips for Semi-Truck Maintenance & Driver Safety
As temperatures rise and the days get longer, it’s essential to ensure your semi-truck fleets are protected. Summer presents unique challenges not only for semi-trucks, but also for the drivers who operate them. High temperatures can exacerbate existing mechanical issues and significantly affect driver health, making preventive measures and proper preparation vital in the summer months.
In this article, the experts at TLG explore essential summer safety tips for fleet managers and drivers, from keeping cooling systems in check to ensuring drivers stay hydrated and alert. We’ll cover the critical aspects that contribute to a safe and efficient operation throughout the warmer months, and whether you’re overseeing a fleet or behind the wheel, these tips will help you navigate the summer safely and smoothly.
Summer Semi-Truck Maintenance Practices
Soaring temperatures can take a toll on the mechanical integrity of semi-trucks, making it essential to focus on preventive maintenance to ensure your fleet remains reliable and efficient during the hottest months of the year. There are a few specific maintenance areas that are particularly important in the summer, from the cooling system to the air conditioning, to help fleet operators keep their vehicles in peak condition regardless of the weather.
Cooling System Maintenance
Having a well-maintained cooling system is vital for preventing engine overheating, a common issue during summer. Start by checking the radiator for any signs of blockage or damage, as even minor debris can impact airflow and cooling efficiency. Ensure that the coolant level is adequate and consider replacing old coolant that may no longer be effective. You should also regularly inspect hoses and clamps for wear and leaks, as these are often the first points of failure in a semi-truck cooling system. Finally, check the water pump functionality to ensure it is properly circulating coolant to all the necessary systems and components.
Tire Maintenance and Care
Tires are severely affected by high temperatures, which can increase the risk of blowouts on the road. Begin each trip with a tire pressure check, adjusting it according to the manufacturer’s recommendations and considering the increase in air pressure as temperatures rise. Inspect your truck’s tires for uneven wear patterns, cuts, or bulges in sidewalls, and rotate tires regularly to promote even wear, replacing any that are worn beyond safety margins. Also, consider using tire covers when parked for extended periods to protect your tires against UV damage and excessive heat.
Brake System Check
The brake system’s efficiency can decline if components overheat. Ensure that all parts of the brake system, including pads, linings, drums, and rotors, are checked for signs of excessive wear or damage. Brake fluid levels should be topped off before every trip, and the fluid should be changed if it appears dirty or contaminated, as it can absorb moisture and reduce braking efficiency. Additionally, ensure that air brakes are moisture-free and don’t have any air leaks to maintain optimal performance.
Battery Care
High temperatures can lead to faster battery degradation by speeding up the chemical reactions inside and causing essential fluids to evaporate. Throughout the summer months, check the oil level regularly and change the oil and filter according to the manufacturer’s schedule (or more frequently if operating in extremely hot or dusty conditions). You may also consider using a higher viscosity oil for the summer months, as it is less prone to thinning at high temperatures.
Air Conditioning and Ventilation
Keeping the air conditioning system in top shape is vital for both the comfort of the driver and the safe operation of electronic components, which can malfunction or degrade if overheated. Ensure the refrigerant level is sufficient and that the system is free of leaks. To improve airflow and cooling efficiency, it’s also recommended to clean or replace the cabin air filters regularly, and to check the compressor and belts for wear and functionality.
Summer Safety Tips for Semi-Truck Drivers
While the maintenance of semi-trucks is critical, the health and safety of the drivers are equally important, especially during the intense heat of summer. High temperatures can lead to dehydration, fatigue, and heat-related illnesses, which can significantly impair a driver’s ability to operate a vehicle safely. Here are the best ways to ensure drivers maintain their well-being and safety while driving during the summer months:
Hydration and Nutrition
Staying hydrated is essential in preventing heat-related health issues. Drivers should carry and consume ample amounts of water throughout the day, aiming for at least 64 ounces. However, if the temperature climbs or you are physically active, you should consume more than 64 ounces per day. It’s also recommended to avoid caffeinated and sugary drinks because they can lead to dehydration. Nutrition also plays a vital role in maintaining energy and hydration levels; snacks like fruits, vegetables, and nuts are ideal as they contain water, vitamins, and minerals that help keep hydration levels up and provide sustained energy.
Managing Fatigue and Heat Stress
Extended exposure to heat can cause fatigue, making it essential for drivers to take regular breaks. Utilize air-conditioned rest areas to cool down, and before you get back on the road, ensure you’re fully rested to avoid exhaustion. Heat exhaustion can significantly impact your overall health, so be aware of the symptoms to watch for, which include heavy sweating, weakness, pale and clammy skin, fainting, and vomiting. If you begin experiencing the symptoms of heat exhaustion, take immediate action by moving to a cooler environment, and seek medical attention if symptoms do not improve.
Dress Appropriately
Choosing the right attire can greatly influence a driver’s comfort and safety. Opt for lightweight, loose-fitting clothing that allows your body to breathe and cool effectively. Light colors are preferable, as they reflect rather than absorb the sun’s rays. Sunglasses should also be worn to protect your eyes from harmful UV rays, and a broad-brimmed hat can provide additional protection to reduce the risk of sunburn. Finally, don’t forget to apply sunscreen with an SPF rating of at least 30 to all exposed skin, as you are susceptible to sunburn even in the cab of your truck.
Prepare for Emergencies
Like any other haul, it’s essential to have a well-equipped emergency kit for summer driving. This kit should include extra water for hydration, non-perishable food items, a first-aid kit, a flashlight with extra batteries, a reflective sunshade for the windshield, and basic truck maintenance tools. In the summer specifically, it’s also helpful to include coolant and engine oil for vehicle-related emergencies. Knowing the signs of vehicle distress and having the resources to manage minor breakdowns can prevent a bad situation from becoming worse, but if you need assistance on the road, you can always contact your local TLG Peterbilt dealership or utilize TLG’s Road Guru mobile service fleet for your semi-truck repairs.
