Summer heat accelerates battery decline, thins engine oil, and increases tire pressure—all of which can lead to dangerous situations on the road. In fact, an overheated motor is the number one cause of summer breakdowns. The risk of overheating especially skyrockets during the summer months, and as temperatures climb into the 80s and 90s, your tires are at a higher risk for a blowout.

Whether you're planning a road trip through Utah's scenic highways or just commuting to work, a little preventative care now can save you from being stranded in triple-digit heat. The good news? Many summer maintenance tasks are simple enough to do yourself, while others require professional attention.

Your Essential Summer Car Maintenance Checklist

The scorching summer sun in Utah can be beautiful, but it's also tough on our vehicles. High temperatures can put additional strain on your engine and accelerate wear and tear on various components. This section will detail the core components that need attention during hot weather, explaining why each is critical for safety and performance.

Keep Your Engine and Battery Cool

One of the biggest threats to your vehicle in summer is the risk of overheating. Rising outdoor temperatures already heat your car’s engine, and when combined with the internal heat generated by the engine itself, it creates a perfect storm for trouble. An overheated motor is, unfortunately, the number one cause of summer breakdowns.

Our car’s cooling system is its primary defense against this heat. It circulates a mixture of coolant (antifreeze and water) through the engine to absorb heat and then dissipates it through the radiator. If your cooling system isn't functioning optimally, the risk of overheating skyrockets, especially during Utah’s hot summer months.

Beyond the engine, the summer heat can also significantly impact your car's battery. While many of us associate dead batteries with frigid winter mornings, summer heat is actually tougher on your car’s battery in the long run. High temperatures can evaporate your battery's liquids faster, draining its charge and reducing its overall lifespan. This internal damage might not manifest as a dead battery until the colder months, but the damage is done in the heat.

To keep your engine running smoothly and prevent costly repairs, regular checks are crucial:

• Check Your Engine Oil: High temperatures can thin out engine oil, making it less effective at lubricating moving parts. This can lead to increased friction and decreased fuel efficiency. Regularly checking your oil is a simple, yet highly effective step in your summer car maintenance. It helps avoid extreme wear, overheating, and engine issues in the long-run. We recommend checking your engine oil once a month. To do this, simply pull the dipstick out (while the car is off and cool), wipe off the excess oil with a clean cloth or paper towel, reinsert it fully, then pull it out again to check the level. Clean engine oil should appear brown or black, and the level should fall between the 'MIN' and 'MAX' lines. For a detailed guide, you can refer to how to check your engine oil.

• Inspect Belts and Hoses: The belts and hoses in your engine compartment are vital for several systems, including the cooling system and accessory functions. Inspect radiator hoses for signs of wear, such as brittleness, bulging, or excessive softness, and check for any leaks. Similarly, examine drive belts (like the serpentine belt) for cracks, glazing, or fraying. While modern multi-rib drive belts might not show visible wear as readily as older ones, a general rule of thumb is to replace serpentine belts every 90,000 miles. A broken belt can cause significant engine damage, so it’s better to be proactive.

• Battery Terminal Cleaning and Testing: Since summer heat accelerates battery decline, it's wise to keep an eye on your battery. Cleaning battery terminals once every month or two can help prevent corrosion, which can interfere with the battery's ability to hold a charge. You can easily do this with a wire brush. If your car battery is more than three years old, we recommend having its voltage tested by a professional to determine its remaining capacity. This preventative measure can save you from a frustrating breakdown on a hot day.

Key Fluids for Summer Car Maintenance

Fluids are the lifeblood of your vehicle, and their proper levels and condition are especially critical during the summer. When fluid levels are low, it significantly increases the possibility of your vehicle overheating and not working efficiently.

Here’s what we always check:

• Engine Oil: As we mentioned, high temperatures can thin out engine oil, reducing its ability to lubricate and protect your engine. For drivers in Utah facing extreme heat, synthetic oil is often a superior choice. Yes, synthetic oil is more suitable for your car’s functionality under high temperatures and offers greater protection, especially for older and high-mileage cars. It maintains its viscosity better in heat, ensuring consistent lubrication.

• Coolant (Antifreeze): Your car's cooling system relies on a proper mix of coolant and water, typically a 50/50 ratio. This mixture prevents your engine from overheating and protects against corrosion. We recommend checking and topping off your coolant levels every few weeks during the summer. You should also consider having your engine's cooling system flushed periodically as recommended by your manufacturer to ensure it's free of contaminants and functioning optimally.

• Brake Fluid: The brake system is your car's most important safety feature. In summer, increased vehicle use for road trips and activities means your brakes might work harder. Check your brake fluid; clear fluid indicates it’s healthy, while dark and dirty fluid can signal a larger internal issue that needs professional attention.

• Transmission Fluid: This fluid lubricates, cools, and helps with smooth gear shifting. Low or overheated transmission fluid can lead to shifting difficulties and potential damage. Check your transmission fluid regularly—at least once a year—to ensure it hasn't gotten low or overheated.

• Windshield Washer Fluid: While perhaps not as critical as engine oil, clear visibility is always paramount for safe driving. Summer in Utah can bring sudden thunderstorms or an onslaught of bugs. Keep your washer fluid reservoir full, and consider using a summer-specific bug remover formula. This type of fluid is specifically designed to cut through stubborn road grime and insect splatter, ensuring clear visibility even after a long drive.

Tires and Brakes: Your Connection to the Road

Your tires are the only part of your car that touches the road, and their condition is paramount for safety, especially in the summer heat. Similarly, your brakes are your primary safety system, and they need to be in top shape to handle summer driving.

• Tire Pressure (PSI): This is a big one for summer! Every temperature change of 10 degrees affects your tire pressure by around one or two pounds per square inch (PSI). As temperatures climb into the 80s and 90s, your tires are at a higher risk of a blowout. Under-inflated tires can cause blowouts, especially when the road is extremely hot, which is common in Utah during the summer months. Pavement that’s been sizzling under the summer sun can increase the chance of tire blowouts while on the road, especially if your tires are worn or underinflated. We recommend checking your tire pressure at least once a month when the tires are cool (before you’ve driven for any significant distance) for the most accurate reading. You can find the recommended PSI for your vehicle on a sticker inside your driver's door or in your owner's manual; typically, it's between 32 and 35 PSI.

• Tire Tread Depth: Adequate tread depth is crucial for traction, especially during summer rainstorms. The easiest way to check the tread on your tires is to use the “penny test”. Simply take a penny and place it upside down into one of the grooves of each tire. If you can see the top of Abraham Lincoln's head, your tire tread is worn past the point of being safe, and it may be time to consider new tires.

• Tire Rotation: To ensure even wear and prolong the life of your tires (which can save you money!), we recommend rotating your tires every 5,000-8,000 miles. Check your owner's manual for specific instructions for your vehicle.

• Brake Inspection: Your brakes work hard, especially if you're taking on Utah's mountain roads or starting on long summer road trips. Pay close attention to any squeaking or grinding sounds while braking, or if you feel a vibration. These are signs that your brakes need inspection. Before any long summer drives, it’s always a good idea to schedule a brake inspection to ensure everything is in top working order.

Protecting Your Car's Interior and Exterior

The sun in Utah is intense, and while we love the sunny days, prolonged exposure can take a toll on your car's appearance and comfort. Protecting your vehicle's interior and exterior from sun damage is just as important as mechanical maintenance.

A/C System Readiness

A properly functioning air conditioning system isn't just about comfort; in Utah's summer heat, it can be a safety measure. A car without A/C during the summer can quickly become unbearable, or even a health risk. So, ensuring your A/C is ready is a key part of summer car maintenance.

• Signs of Trouble: If your A/C system isn't blowing cool air, or if the airflow feels weak, it’s time for a check-up. Strange smells or sounds coming from the vents are also indicators of a problem.
• Refrigerant Levels: If your A/C is not working properly, it might be low on refrigerant due to a leak. Modern A/C systems are tightly sealed, so a low refrigerant level usually indicates a leak that needs professional service.
• Cabin Air Filter: A clogged cabin air filter can significantly reduce airflow and introduce allergens and dust into your car. We recommend cleaning or changing your cabin air filter (if equipped) before summer begins for optimal air quality and flow.
• Compressor Function: The refrigerant in your A/C system carries oil that lubricates the compressor and keeps seals moist. Believe it or not, running your A/C periodically, even in the winter, helps maintain these components and can reduce refrigerant loss.

Shielding Your Car from Sun Damage

Extreme heat and prolonged exposure to sunlight can seriously damage your car’s interior and exterior. Materials like leather, plastic, and fabric can fade, crack, or deteriorate over time. The sun's UV rays can also dull your paint finish.

Here are our top tips for protecting your car:

• Park in the Shade: This is the simplest and most effective defense. Whenever possible, park your car in the shade. This helps to keep the interior cooler and reduces direct UV exposure to both the interior and exterior.
• Use a Windshield Sunshade: These inexpensive accessories are incredibly effective at blocking direct sunlight from entering your car through the windshield. They can significantly reduce dashboard temperatures and protect your interior from fading and cracking.
• Apply UV Protectant Sprays: For surfaces like your dashboard, door panels, and leather or vinyl seats, consider applying UV protectant sprays. These products create a barrier against harmful UV rays, helping to preserve the material's color and prevent cracking.
• Consider Window Tinting: Professionally installed window tinting can offer additional protection by blocking a significant amount of UV radiation and reducing heat buildup inside the cabin.
• Regular Washing and Waxing: Don't underestimate the power of a clean car! Regularly running your vehicle through a car wash does more than just keep it looking great—it helps protect essential parts of your vehicle, like the undercarriage, from rust and corrosion. Specifically, regular car washes can remove contaminants that can damage your paint. Following up with a fresh coat of wax adds an extra layer of protection against the harsh summer sun, acting as a shield for your paint.

Frequently Asked Questions about Summer Vehicle Care

We often hear similar questions from our customers about preparing their vehicles for the summer. Here are some of the most common ones:

What are the first signs my car is overheating?

It’s crucial to recognize the warning signs of an overheating engine, especially in Utah’s summer heat. If you notice any of these, pull over immediately and shut off your engine:

• Rising Temperature Gauge: This is the most obvious sign. If your car’s temperature gauge starts creeping into the red zone, your engine is getting too hot.
• Steam from Under the Hood: This is a clear indicator that coolant is boiling and escaping the system.
• Strange Engine Smells: A sweet, syrupy smell (like maple syrup) often indicates a coolant leak, while a burning smell could be oil or other fluids.
• Loss of Power: An engine that's too hot may struggle to perform, leading to sluggish acceleration or a noticeable loss of power.

If your car starts to overheat while driving in hot weather, pull over immediately to a safe location, shut off the car for about 15 minutes, and call for assistance. Continuing to drive an overheating engine can cause severe, long-term harm and costly repairs.

When is the best time to get my car serviced for summer?

The ideal time to get your car serviced for summer car maintenance is in late spring, before the first major heatwave hits Utah. Preparing early on gives you the perfect opportunity to address any major issues and prevent being caught off guard by delays or unexpected breakdowns. It’s also wise to schedule a comprehensive check-up prior to any long summer road trips you might be planning. This proactive approach ensures your vehicle is reliable and safe for all your summer adventures.

How often should I change my oil during the summer?

The frequency of your oil changes depends on several factors, including your car's make and model, the type of oil used, and your driving habits. Most modern cars today can easily go 5,000-7,500 miles or more between oil changes. We always recommend checking your vehicle's owner's manual for the manufacturer's specific recommendation.

However, summer driving conditions, especially in Utah's high temperatures, can put extra strain on your engine and oil. If you frequently:
