Fleet Maintenance Checklist: Keeping Your Vehicles Running Efficiently in Summer

June 16, 2025

Summer heat isn’t just tough on people, it’s tough on fleet vehicles, too. At Action Supply, we understand how critical fleet reliability is to your operations. Whether you're hauling heavy loads, navigating tight job sites, or servicing offshore projects, extreme temperatures and humidity can take a serious toll on your equipment.



Now’s the time to make sure your vehicles are prepared to handle the demands of summer. Use this practical maintenance checklist to help avoid costly breakdowns and keep your fleet running smoothly all season long.


1. Check and Top Off All Fluids

Hot weather causes fluids to evaporate more quickly, which can lead to overheating or system failure.


Make sure to check:


  • Engine oil
  • Transmission fluid
  • Brake fluid
  • Power steering fluid
  • Coolant/antifreeze


Keep extra fluid on hand and make topping off a regular part of your fleet inspections.


2. Test the Battery

High heat can shorten a battery’s lifespan by evaporating internal fluids and increasing corrosion. Inspect terminals for buildup and ensure batteries are fully charged and securely mounted. If a battery is more than three years old, consider replacing it before summer puts it to the test.


3. Inspect Belts and Hoses

Belts and hoses are especially vulnerable to cracking and failure in high temperatures. Look for:


  • Soft spots
  • Bulges
  • Fraying or cracking
  • Loose connections


At Action Supply, we stock a wide selection of industrial hoses and hydraulic fittings so your crew can get what they need without delay.


4. Ensure the Cooling System Is Working Properly

Your engine cooling system is the frontline defense against heat-related breakdowns. Inspect the radiator, water pump, thermostat, and hoses for signs of wear. Make sure the coolant is clean, filled to the correct level, and mixed according to manufacturer specs.


5. Inspect Tire Condition and Pressure

Hot pavement can cause under inflated tires to flex more than usual, increasing the risk of blowouts. Check:


  • Tread depth
  • Tire pressure (often affected by heat)
  • Sidewall condition


Don't forget spare tires and trailer tires, too.


6. Stock Up on Emergency Supplies

Every fleet vehicle should carry a summer-ready emergency kit including:


  • Extra water
  • First-aid kit
  • Reflective triangles or flares
  • Jumper cables
  • Fire extinguisher
  • Portable fan or cooling towels


Need supplies? Action Supply offers PPE and safety gear designed for Texas heat and demanding environments.


7. Schedule Preventive Maintenance in Advance

Don’t wait until a problem arises. Schedule preventive inspections and servicing now to beat the summer rush. Routine checkups can catch small issues before they become major disruptions.

The start of a new year is more than a calendar reset, it’s an opportunity to strengthen the systems that keep your business running efficiently. For industrial, commercial, and maintenance-driven operations, having the right supplies in place at the right time can mean the difference between staying productive or falling behind. Building a smarter supply strategy early in the year helps businesses control costs, reduce downtime, and remain competitive in an increasingly unpredictable supply environment. Here’s how to evaluate your needs, forecast usage, and put reliable systems in place for the year ahead. Why Strategic Supply Planning Matters Reactive purchasing often leads to higher costs, rushed decisions, and inconsistent inventory levels. Without a clear supply plan, businesses risk overordering, stockouts, and delays that impact operations and customer commitments. Strategic supply planning allows organizations to: Improve operational efficiency Reduce emergency purchases and downtime Stabilize pricing through better forecasting Build stronger supplier relationships When supply strategy is aligned with operational goals, purchasing becomes a competitive advantage, not just a necessity. Step 1: Evaluate Your Current Supply Usage The foundation of any effective supply strategy is understanding what you actually use. Reviewing historical purchasing data provides valuable insight into patterns, seasonality, and inefficiencies. Key questions to ask: Which products are used consistently throughout the year? Where do usage spikes or slowdowns occur? Which items frequently require rush orders or last-minute replenishment? Identifying high-use and critical items helps prioritize where planning and standardization will have the greatest impact. Step 2: Forecast Demand with Operational Input Accurate forecasting requires collaboration across departments. Operations, maintenance, and procurement teams all play a role in anticipating demand. Consider factors such as: Planned maintenance schedules Production volume expectations Seasonal workload fluctuations Equipment upgrades or expansions By incorporating operational insight into forecasting, businesses can better align inventory levels with real-world needs, reducing both excess stock and shortages. Step 3: Standardize Products and Vendors Standardization simplifies purchasing, improves consistency, and often reduces costs. Evaluating opportunities to standardize frequently used supplies—such as safety products, fasteners, tools, or consumables—can streamline procurement and inventory management. Working with a trusted supplier also provides access to product expertise, availability insights, and alternative solutions when supply challenges arise. Step 4: Set Systems in Place Early Establishing purchasing systems early in the year creates stability throughout the months ahead. This may include setting reorder points, implementing blanket orders, or coordinating scheduled deliveries for high-use items. Proactive systems reduce the need for emergency purchases and allow teams to focus on operations rather than constant supply management. Step 5: Build a Supply Partner, Not Just a Vendor A strong supply strategy goes beyond transactions. Partnering with a knowledgeable supplier adds value through product recommendations, inventory support, and responsiveness when challenges arise. The right supply partner understands your business, anticipates needs, and helps you adapt as conditions change throughout the year. How Action Supply Supports Smarter Supply Planning Action Supply works with businesses to develop supply strategies that support efficiency, reliability, and long-term success. By helping customers evaluate usage, identify opportunities for standardization, and implement dependable supply systems, Action Supply helps operations stay prepared, not reactive. Whether planning for routine maintenance, large-scale projects, or day-to-day operations, Action Supply provides the products and support businesses need to stay competitive all year. FAQs Why is supply planning important at the start of the year? Early planning helps businesses forecast demand, stabilize costs, and reduce disruptions caused by shortages or emergency purchases. How can businesses improve inventory efficiency? Evaluating usage data, forecasting demand, standardizing products, and working with a reliable supplier are key steps toward more efficient inventory management. What should a supply strategy include? A strong supply strategy includes usage evaluation, demand forecasting, product standardization, purchasing systems, and a trusted supply partner.
