As the fall season approaches, truck fleets across the country are gearing up for the seasonal shift. The crisp air and changing leaves signify more than just the arrival of autumn; they serve as a reminder that it’s time to adjust your fleet’s maintenance schedule. Preparing your trucks for the cooler temperatures, potential road hazards, and increased demands of the season is crucial. A well-crafted maintenance schedule not only ensures the reliability of your fleet but also minimizes downtime, which can be costly as we get close to the holiday season. So, let’s dive into how to prepare your fleet for the fall effectively.
Before we get into the nuts and bolts of creating a fall maintenance schedule, it’s important to understand how this season uniquely impacts your fleet. The cooler temperatures can affect everything from tire pressure to engine performance. Additionally, the increase in wet conditions from rain and early frost can put extra strain on your truck's braking systems and tires. This means that changing to winter tires early will help increase road safety.
As temperatures begin to drop, certain fluids in your trucks become more viscous, which can affect the performance of critical components. Start by checking the coolant. During the fall, you need to ensure that the coolant has the correct antifreeze mixture to prevent the engine from freezing as temperatures plummet overnight. Coolant levels should be topped off, and it’s wise to consider flushing and replacing it if the fluid is old or contaminated.
Next, examine the engine oil. Cooler weather can cause oil to thicken, reducing its ability to lubricate the engine effectively. If your fleet operates in regions where fall temperatures can get quite low, consider switching to a lower-viscosity oil to ensure smooth engine operation.
Don’t forget about transmission fluid or oil. It should be inspected for signs of contamination or wear. It’s best to get high-quality oil like synthetic oils. Not only will your transmission wear less but the oil is specifically designed for the transmission to work efficiently. If it’s been a while since the transmission was changed, now is the time. Or stick with manufacturer recommendations. Our shop recommends every 30,000 to 60,000 miles as it may degrade after long periods.
Your tires are the only point of contact between your truck and the road, making their condition critical as road conditions worsen in the fall. Start by checking the tread depth on all tires. Worn tread can lead to poor traction on wet or icy roads, increasing the risk of accidents. The tire pressure should also be checked regularly. As temperatures drop, tire pressure decreases, which can lead to uneven tire wear and reduced fuel efficiency.
Consider swapping out summer tires for all-season or winter tires if your fleet operates in areas where fall can bring snow or ice. These tires offer better grip in cooler conditions. There will be no decrease in wear during operations but an increase in safety on icier roads.
The fall season can be tough on batteries, especially as cooler temperatures require more power to start the engine. Inspect each truck’s battery for any signs of corrosion or wear. It’s a good idea to test the battery’s charge to ensure it’s holding a proper charge and won’t fail as the weather continues to cool down.
In addition to the battery, check all electrical systems including lighters. The shorter days of fall mean more nighttime driving, so ensure all lights are functioning, windshield wipers, and h correctly. Windshield wipers should be checked for wear, as they’ll be dealing with increased rain and possibly early snow. You should always check to see if your dashboard works properly. These signs will let you know when other aspects of your heavy-duty vehicle get damaged or at risk.
As fall weather can be unpredictable, your fleet’s HVAC systems need to be in top shape. Test the heating system to ensure that it is working properly and capable of keeping the cab warm. A functioning heater is essential to keeping the windshield clear of fog and frost. It’s especially important to have it checked if you haven’t already during the summer as the weather transition may impact your HVAC system.
Drivers should also get their defroster checked to make sure it can quickly and effectively clear the windshield. A malfunctioning defroster can significantly impair visibility, which is dangerous when driving conditions are less than ideal.
Your brakes will be under increased stress during the fall, particularly in wet and slippery conditions. This makes it crucial to inspect the brake drums for wear. If the drums are thin or the slack adjusters show signs of damage, replace them before they fail.
Ensure that the brake lines are free from leaks and that the air system is working correctly if your fleet uses air brakes. Fall is also a good time to check the ABS (Anti-lock Braking System) sensors to ensure they are functioning properly, as they play a vital role in preventing skidding during emergency stops.
The driveline and suspension components must be in top condition to handle the rigors of fall weather. Inspect the driveshafts, U-joints, and differential for any signs of wear or damage. The suspension should also be checked to ensure it can handle the added stress from rougher road conditions and heavier loads that might be more common in the fall. Fall is a great time to lubricate these components as part of your preventive maintenance routine. Regular lubrication can prevent premature wear and reduce the risk of costly repairs down the road.
Creating a comprehensive fall maintenance schedule is only half the battle, implementing it effectively is crucial. Utilize fleet management software to track the maintenance tasks for each truck, ensuring that nothing falls through the cracks. Schedule inspections and maintenance well in advance to avoid the last-minute rush that often accompanies the change of seasons. Train your drivers to recognize early signs of issues such as unusual noises, decreased braking efficiency, or difficulty starting the engine. Encourage them to report these issues immediately so they can be addressed before they lead to bigger problems.
Despite your best efforts, breakdowns can still occur, especially with the challenges that fall weather brings. Make sure each truck is equipped with an emergency kit that includes items like road flares, a jack, a spare tire, and basic tools. Consider adding cold-weather gear like blankets and extra gloves in case of an emergency. Or if the damage is too large for a DIY repair, have contact with reputable mobile, roadside, or towing shops to reduce downtime.
Creating a fall maintenance schedule for your truck fleet is an essential step in ensuring your vehicles remain reliable and safe as the season changes. By paying close attention to the unique challenges that fall presents, from cooler temperatures to wetter road conditions, you can minimize downtime and keep your fleet running smoothly. Regular inspections and proactive maintenance are the keys to success. With these tips from Brant Jones, you’ll be well on your way to navigating the fall season with confidence.
