Tips For Maintaining Heavy-Duty Truck Engines In Arizona's Hot Climate

Heavy-duty truck receiving engine repair in Arizona

Arizona has a reputation for being an incredibly hot place for the vast majority of the year. This constant and intense heat is generally cause for alarm with respect to maintaining an adequate engine temperature in your heavy-duty truck. After all, the more your coolant system has to work to cool your engine, the more it has to be maintained to avoid potential failure. In this article, we’ll be discussing the various ways in which you maintain your heavy-duty truck engine, as well as the system that cools it, to adequately combat Arizona’s hot climate. 

If you’re looking for a heavy-duty repair shop in Prescott, Valley, to maintain your truck’s coolant system, you’re in luck. Give us a call here at Arizona Fleet Service today to schedule an appointment. 

Heavy-Duty Diesel Truck Coolant Systems 

Every heavy-duty diesel truck on the road has a coolant system designed to keep its engine’s temperature under a certain threshold. This system essentially allows for a heat transfer to take place. In other words, heat is absorbed from your engine and released into the outside air. In order to make this heat transfer happen reliably, maintenance must be done on a regular basis. Before we get into how your coolant system is physically maintained, let’s jump into how it works. 

Understanding Your Coolant System 

To understand your coolant system, you must understand what coolant actually is. Some confuse coolant with your engine oil, but coolant is actually an entirely different liquid altogether. Rather than lubricating components to reduce friction, the coolant absorbs the radiant heat from in and around your engine. To ensure this happens, a component called a water pump pushes your coolant through your engine block. 

At this point, a significant amount of heat created by your engine is absorbed. From here, your coolant flows through your radiator, where it encounters a series of coolant channels. While your coolant flows through these coolant channels, outside air is pulled across the fluid lines, effectively dissipating the heat. The air that’s pulled from the outside of your vehicle is pulled in using what’s called a fan clutch. A fan clutch is essentially a thermodynamic device responsible for activating and deactivating your cooling fan when necessary. 

How Hot Climates Impact Your Coolant System

Hot climates can significantly impact a truck's coolant system, leading to several potential issues. One primary concern is the risk of overheating. In a hot climate, the engine works harder to maintain an optimal operating temperature, placing additional strain on the coolant system. If the system isn't working efficiently or is low on coolant, the engine can easily overheat, causing severe damage.

Coolant Evaporation 

Furthermore, hot temperatures accelerate the rate of coolant evaporation, which may lead to low coolant levels quicker than in milder climates. If the coolant levels are not regularly checked and topped off, it can again result in overheating.

Component Degradation 

Additionally, consistent exposure to high temperatures can degrade the components of the cooling system, including the radiator, hoses, and water pump, leading to leaks or failures. The thermostat can also become less effective over time, impairing its ability to accurately control the flow of coolant through the system. The heat can also cause the coolant to break down faster, reducing its effectiveness and potentially leading to corrosive damage within the cooling system.

How Arizona Fleet Service Can Protect Your Coolant System 

Coolant Flushes for Optimal Performance in Arizona’s Climate 

One of our mainstay services is coolant flushing. This process involves removing the old coolant, cleaning the system to remove any build-up of rust or scale deposits, and then refilling with fresh coolant. A coolant flush is an excellent way to extend the life of your cooling system, prevent corrosion, and keep your engine running smoothly.

Fan Clutch Repairs for Adequate Cooling in Arizona’s Climate

Another crucial component we service is the fan clutch. The fan clutch engages and disengages the cooling fan at the right times, maintaining the engine's correct temperature. Our technicians are skilled in diagnosing and repairing fan clutch issues, ensuring your engine doesn’t overheat, especially under heavy loads or in our hot Arizona climate.

Plugged Radiator Flushes for Proper Coolant Flow 

Plugged radiators are another common issue that we regularly address. Over time, debris, sediment, and rust can clog the radiator, impeding the flow of coolant and leading to overheating. Our team uses advanced diagnostic tools to detect blockages and has the expertise to clean or replace your radiator as needed.
