Even in sunny Yuma, AZ, cold weather can still have a surprising impact on your vehicle. While we don’t face the deep freezes or heavy snow that other parts of the country endure, the cooler months bring unique challenges for drivers. Preparing your car for the seasonal shift ensures that it runs smoothly, keeps you safe, and helps you avoid any unexpected repair costs.

At Accurate Automotive Attention, we’ve been helping Yuma drivers maintain their vehicles since 1969, and we’re here to guide you through the essentials of getting your car ready for cold weather. The key points below will help ensure your vehicle is in top shape to handle whatever Mother Nature throws at us during Yuma’s colder months.

1. Battery Health: Keep the Juice Flowing

Cooler temperatures can be tough on your car’s battery, even in Yuma’s mild winters. Battery power tends to diminish as temperatures fall, which can make it harder to start your engine. A weak battery might work just fine during summer, but when the weather cools down, you may find yourself stranded with a car that won’t start.

What to do:

• Test the battery. Have the charge and voltage checked to ensure your battery has enough power to last through the season. At Accurate Automotive Attention, we offer quick battery tests to see if your battery is strong enough or if it’s time for a replacement.
• Inspect for corrosion. Check the battery terminals for corrosion or buildup, which can interfere with the electrical connection. Cleaning the terminals or tightening any loose connections can prevent issues.
• Replace if necessary. If your battery is more than three years old, it’s a good idea to have it inspected or replaced to avoid sudden failure during cooler weather.

2. Tires: Tread Carefully

Your tires are your vehicle’s only point of contact with the road, so it’s crucial that they’re in good condition for any change in weather. While snow isn’t an issue in Yuma, the cooler months can still bring rain or slippery roads. Tire performance can also decrease if the air pressure isn’t optimized for the lower temperatures.

What to do:

• Check tire pressure. Cold air causes tire pressure to drop, which can reduce traction and fuel efficiency. Make sure your tires are properly inflated according to the manufacturer’s specifications. Low tire pressure can also lead to uneven tire wear, costing you more in the long run.
• Inspect the tread. Good tire tread helps maintain traction on wet or slick roads. Use the penny test: insert a penny into the tread groove with Lincoln’s head upside down. If you can see all of Lincoln’s head, it’s time to replace your tires.
• Consider all-season tires. If you plan on taking road trips to cooler areas or mountainous regions, all-season tires might offer better performance in mixed weather conditions.

3. Engine Oil: Cold Weather, Thicker Oil

Engine oil is the lifeblood of your vehicle, but colder weather can cause it to thicken, making it harder for the engine to circulate properly. This can lead to poor engine performance or even damage over time. While Yuma doesn’t see freezing temperatures, it’s still important to ensure your oil is suited for the cooler months.

What to do:

• Check your oil. Make sure you’re up to date on oil changes, especially as the season changes. Regular oil changes keep your engine running smoothly and efficiently.
• Use the right oil viscosity. If temperatures drop, your engine might benefit from oil with a lower viscosity (thinner oil). Our team can recommend the best oil for your vehicle and climate.

4. Coolant: Keeping Your Engine Cool and Warm

The coolant in your car’s cooling system does more than keep your engine from overheating in the summer. In cooler months, it prevents the engine from freezing and protects it from the wear and tear of temperature changes. Even in Yuma’s mild winters, your cooling system plays a critical role in maintaining engine temperature which is the function of the engine’s thermostat.

What to do:

• Check coolant levels. Ensure your car’s coolant (also known as antifreeze) is topped up and at the proper mix ratio. In areas with more extreme cold, a 50/50 mix of water and antifreeze is recommended, but here in Yuma, you might be able to get away with a 60/40 mix.
• Inspect for leaks. Look for any signs of leaks in your cooling system. A small coolant leak can lead to bigger problems such as engine overheating if left unaddressed.

5. Windshield Wipers and Washer Fluid: See Clearly, Drive Safely

Clear visibility is essential for safe driving, especially during the cooler months when rain is more frequent. Over time, your windshield wipers can crack or wear down, reducing their effectiveness. Additionally, regular washer fluid may not perform as well in cooler temperatures, leaving streaks or ice on your windshield.

What to do:

• Replace old wipers. If your wipers leave streaks, squeak, or skip across the glass, it’s time for a replacement. Consider winter-grade wiper blades for improved performance in cooler weather.
• Refill washer fluid. Use washer fluid with antifreeze properties to prevent it from freezing on your windshield in cooler weather. This can also help dissolve ice or frost on those chilly desert mornings.

6. Heating System: Stay Warm and Defrosted

Even though we’re not dealing with freezing temperatures in Yuma, you’ll still want a functional heating system for those cooler mornings and evenings. Additionally, a properly working defroster is essential to keep your windshield clear of condensation or frost.

What to do:

• Test the heater. Before the cooler weather hits, turn on your car’s heater to make sure it’s functioning properly. If it’s blowing cool air or taking a long time to heat up, there could be an issue with the heater core, thermostat or coolant levels.
• Check the defroster. Make sure your front and rear defrosters are working to ensure clear visibility on cooler mornings. If you notice any problems, such as weak airflow or foggy windows, it might indicate a more significant issue that needs to be addressed.

7. Lights: Don’t Be Left in the Dark

With shorter days in the cooler months, you’ll likely be driving in the dark more often. Dim or malfunctioning headlights can reduce your visibility and make driving dangerous, especially on poorly lit roads.

What to do:

• Inspect your lights. Check that all your lights are working, including headlights, brake lights, and turn signals. If any bulbs are dim or burned out, replace them right away.
• Clean your lenses. Over time, dirt and grime can build up on your headlights, reducing their brightness. Clean the lenses to ensure you have maximum visibility at night.

8. Emergency Kit: Be Prepared for the Unexpected

Even though Yuma’s winters are mild, it’s still a good idea to keep an emergency kit in your car. Whether you’re heading into cooler areas or just want to be prepared for a roadside emergency, an emergency kit can provide peace of mind.

What to include:

• A flashlight and extra batteries
• Jumper cables
• A first aid kit
• A blanket
• A basic tool kit
• Non-perishable snacks and bottled water
