When summer temperatures rise, so does the risk of your truck overheating. For hardworking drivers and fleet operators, a breakdown due to engine heat isn’t just inconvenient—it can cost valuable time, money, and even damage your rig.
At Blaine Brothers, we’ve seen firsthand how high temps can wreak havoc on trucks that aren’t properly prepared. Whether you’re hauling cross-country or handling short routes in the Midwest heat, here are our top tips to keep your truck running cool all summer long.
🔧 1. Check and Maintain Your Cooling System
Your cooling system is your first line of defense. Make sure to:
-
Inspect hoses and belts for cracks or wear
-
Check for coolant leaks
-
Top off coolant levels and ensure it’s the proper 50/50 antifreeze-water mix
-
Flush the system at the recommended service intervals
If you’re unsure, schedule a cooling system inspection with our experienced techs before summer hits full swing.
🌬 2. Keep the Radiator Clean
Dirt, bugs, and debris can block airflow and reduce the radiator’s ability to cool your engine. Pressure wash the radiator fins regularly, and if you’re driving through dusty or buggy areas, consider doing it even more frequently.
Bonus tip: Make sure the radiator cap is functioning properly to maintain pressure in the cooling system.
🌡 3. Monitor Engine Temperature
Always keep an eye on your temperature gauge. If the needle creeps too high:
-
Reduce your speed
-
Turn off the A/C
-
Pull over and let the engine cool down before popping the hood
Never ignore warning signs. A few minutes of cool-down can save you thousands in repairs.
🛠 4. Test the Thermostat and Water Pump
These two components work together to regulate engine temperature. A stuck thermostat or failing water pump can lead to sudden overheating. If you’re seeing fluctuating temp readings or hear odd noises from the engine, don’t wait—bring it in for a diagnosis.
💨 5. Maintain Your Fan Clutch
Your fan clutch controls airflow across the radiator. If it’s not engaging properly, your engine may not cool down efficiently at idle or low speeds. If your fan is constantly noisy or not turning on when hot, it’s time for a check-up.
🧰 6. Be Prepared with Backup Fluids and Emergency Gear
Keep extra coolant, a funnel, and emergency repair tools on hand. It’s also smart to carry a digital temp gun and basic mechanic gloves for roadside checks.
