Let’s Get Your Rig Ready to Beat the Heat
Summer brings longer hauls, higher temperatures, and new challenges for heavy-duty trucks. Whether you're an owner-operator or manage a fleet, preparing your vehicles for hot weather is essential to avoid unexpected breakdowns, improve safety, and extend the life of your equipment.
Here’s your handy checklist for summer maintenance—with helpful reminders of how Road Choice can keep you ready for whatever the season throws your way.
1. Cooling System Maintenance: Your First Line of Defense
The cooling system becomes your truck's most critical system during summer months. Start with these essential checks:
• Inspect radiator and hoses for cracks, leaks, or bulges that could lead to overheating.
• Flush cooling system to remove built-up deposits that reduce cooling efficiency.
• Replace coolant with the appropriate summer-grade formulation.
• Check cooling fans for proper operation and inspect fan clutches for signs of wear.
• Examine water pump for leaks or unusual noises that might indicate impending failure.
Cooling system failures account for nearly 40% of summer breakdowns, so keep Road Choice in mind for premium coolants and cooling components designed specifically for heavy-duty applications––and backed by our quality guarantee.
2. Air Conditioning System: Driver Comfort Equals Driver Safety
A properly functioning HVAC system isn't just about comfort—it's about safety and productivity:
• Inspect cabin air filters and replace if dirty or clogged.
• Check refrigerant levels and recharge if necessary.
• Test AC operation for proper cooling and airflow.
• Clean condenser fins to ensure maximum heat transfer.
• Examine belts and hoses connected to AC components.
Road Choice carries a complete line of HVAC components and refrigerants that meet or exceed OEM specifications at competitive prices.
3. Battery and Electrical System: Hot Weather Challenges
Summer heat is particularly hard on batteries and electrical components:
• Test battery strength as heat accelerates chemical reactions and water evaporation.
• Clean terminal connections to prevent resistance and voltage drop.
• Check alternator output to ensure proper charging.
• Inspect all wiring for heat-related deterioration or rodent damage.
• Verify proper operation of all lights and electrical accessories.
Road Choice batteries are engineered for extreme temperatures and lasting performance in demanding conditions. Check out our selection if your current battery doesn’t measure up.
4. Tires and Brakes: Safety Under Stress
Higher temperatures mean additional stress on tires and braking systems:
• Check tire pressure regularly as heat causes pressure to increase.
• Inspect tires for uneven wear that might indicate alignment issues.
• Examine brake pads and drums for wear beyond manufacturer specifications.
• Check brake fluid levels and condition to prevent vapor lock in high temperatures.
• Test air brake system for leaks that might become more problematic in hot weather.
Road Choice offers a range of brake components and maintenance products designed for the demands of commercial trucking.
5. Fluids: The Lifeblood of Your Truck
Summer heat places additional demands on all vehicle fluids:
• Check and top off engine coolant. Ensure it's at the proper level and the correct mixture
• Change engine oil to a viscosity grade appropriate for higher temperatures.
• Check transmission fluid for proper level and condition.
Inspect power steering fluid for contamination.
• Top off DEF (Diesel Exhaust Fluid) for emissions systems.
Road Choice offers a comprehensive selection of heavy-duty fluids specifically formulated for summer operating conditions.
6. Filtration Systems: Protecting Your Engine
Summer brings dust, pollen, and increased air particle content:
• Replace air filters to maintain optimal engine breathing.
• Change fuel filters to prevent contamination issues.
• Install fresh oil filters during your summer oil change.
• Consider upgrading to high-efficiency filters for extreme conditions.
