Summer is here, and while the weather is perfect for road trips to the beach, it can also be perfect for car trouble. High heat can take a toll on your vehicle, causing problems such as an overheating engine or a malfunctioning air conditioning system. By doing a little maintenance before the summer heat arrives, you can ensure you’re ready for the summer. Here’s what should be on your summer vehicle maintenance checklist:

1. Check Your Coolant Level

Coolant is one of the most important fluids in your vehicle, as it protects the engine during hot weather. Coolant helps keep your engine from overheating by circulating through the engine block and absorbing heat. If your vehicle doesn’t have enough coolant, high temperatures can make it overheat and damage the engine. Ensure the coolant level is between the minimum and maximum levels of the reservoir.

2. Change Your Cabin Air Filter

Is your vehicle's air conditioner no longer blowing cool air, or does it seem weak? A dirty cabin air filter can result in reduced airflow and a musty scent coming from your air conditioning system. The cabin air filter traps dust, pollen, and debris and can become clogged, restricting airflow. It is generally recommended to change your cabin air filter every 12,000 to 15,000 miles; however, you may need to do it more frequently if you suffer from allergies, as a dirty air filter can worsen allergy symptoms. 

3. Keep Your Car Clean

Not only does washing your car regularly make it look good, but it also helps to protect the finish by reducing the buildup of dirt and grime. Left over time, that dirt and grime can eat away at your vehicle’s finish and undercarriage, leading to rust and corrosion. Summer heat, humidity, and sunlight can cause your paint to fade, crack, or peel. Regular washing and applying quality wax can help keep your car looking its best all year long. 

4. Create an Emergency Kit

In case of an emergency, such as a breakdown or traffic congestion, it’s important to have an emergency kit prepared. In your summer car emergency kit, you should keep the following essentials: water bottles, non-perishable snacks, a first aid kit, sunscreen, jumper cables, a phone charger, a flashlight with extra batteries, and a tire repair kit. 

5. Inspect Your Wiper Blades

Summer storms can strike without warning, so your wiper blades need to be ready when they do. Inspect the rubber squeegee for cracks, tears, or signs of wear. If your wipers skip, squeak, or streak, it’s time for a replacement. Heat can cause the rubber squeegee to stick to the windshield and tear when turned on, so you should lift your wiper blades away from the windshield after parking in hot weather or direct sunlight.  Also, remember to check the rear wiper blade for any problems. 

6. Change Your Engine Air Filter

Your engine air filter keeps dirt and harmful debris from entering and damaging your engine. A dirty or clogged engine air filter can restrict airflow, reduce fuel efficiency, and make your engine work harder. It is typically recommended to change your filter at least once a year or every 12,000 to 15,000 miles. If you live in a dusty or urban environment, you may need to change it more often. 

7. Inspect Your Tires’ Air Pressure

Hot weather can impact your tire pressure because as the temperature rises, the air inside your tires expands, causing the pressure to increase. An overinflated tire can put more stress on your tire wall, leading to poor handling or even a blowout. If your TPMS (Tire Pressure Monitoring System) light is on, check to ensure that all your tires are inflated to the proper pressure. Don’t forget to check your spare tire, as well. 

A little pre-summer maintenance can ensure your vehicle is ready for all your summer adventures. Simple tasks, such as checking your coolant, wipers, and air pressure, as well as creating an emergency kit, changing your cabin and engine air filters, and keeping your vehicle clean, can make a big difference.
