Arizona summers are brutal on commercial trucks. With temperatures regularly exceeding 110°F and pavement temperatures reaching 160°F or higher, your truck's systems are under constant stress.

Here are the essential maintenance practices every trucker should follow during the hot months:

Cooling System Maintenance

Your cooling system works overtime in the desert. Check coolant levels weekly and inspect hoses for cracks or bulges. Consider flushing your cooling system before summer hits. Look for any signs of leaks around the radiator, water pump, and hose connections.

Tire Pressure Management

Heat causes tire pressure to increase. Check your tire pressure in the early morning before the tires warm up. Under-inflated tires generate more heat and are more prone to blowouts. Over-inflated tires have less contact with the road and wear unevenly.

Air Conditioning System

Your A/C isn't just about comfort—it's a safety issue. Driving in extreme heat without functioning air conditioning leads to fatigue and poor decision-making. Have your A/C system inspected and recharged as needed.

Battery Care

Heat is actually harder on batteries than cold. Inspect battery terminals for corrosion, ensure connections are tight, and check electrolyte levels if applicable. Most batteries last 3-5 years, but Arizona heat can shorten that lifespan significantly.

Oil and Fluid Checks

High temperatures break down oil faster. Consider using a higher-viscosity oil during summer months. Check transmission fluid, power steering fluid, and brake fluid regularly.
