Heatwave Hacks: Car Care & Safety Tips for Missouri’s Summers

Things are mild right now–many of us Missourians are enjoying the “calm before the storm”, or rather, the “cool summer weather” before the humidity and heat really start. It looks like we’ve got a hot summer full of heatwaves ahead of us, so now is the perfect time to prepare your vehicle for all things hot weather! In this blog, I’ll talk you through some of the things I suggest to our customers when it comes to getting that car ready for vacations, road trips, or just being parked on hot asphalt while you work. 

Cooling System Maintenance Is Number One

One of the most critical aspects of summer car care is ensuring your vehicle's cooling system is in optimal condition. Missouri's heat can push engines to their limits, making them more prone to overheating. Regular maintenance checks are paramount, including coolant level inspection, radiator flushes, and thermostat assessments. Additionally, keep an eye on any signs of coolant leaks and address them promptly to prevent engine damage.

Tire Care Is Key 

High temperatures can significantly impact tire pressure, leading to underinflation and blowouts. To combat this, it's essential to regularly check your tire pressure, especially before embarking on long journeys. Consult your vehicle's manual for the recommended pressure levels, and invest in a quality tire pressure gauge for accurate readings. Also, check tires for signs of wear and tear, like cracks or bulges, and replace them if needed to ensure you have the best grip and safety on Missouri’s roads.

Air Conditioning System For Comfort

A reliable air conditioning system is a lifesaver during Missouri's scorching summers. Before the heat waves hit, have your AC system inspected by our certified specialists at The Auto Shop. They'll check for refrigerant leaks, clean the condenser coils, and ensure proper airflow within the cabin. A well-maintained AC keeps you cool and comfortable and prevents excessive strain on your engine, improving fuel efficiency in the long run.

Battery Health Is Crucial

Extreme heat can accelerate battery fluid evaporation and lead to corrosion, ultimately affecting your vehicle's starting power. To avoid being stranded on a sweltering day, inspect your battery regularly, especially if it's over three years old. 


The experts at The Auto Shop can perform a thorough battery test to assess its health and recommend replacements if necessary. Keeping the battery connections clean and corrosion-free is also essential for optimal electrical conductivity.

Interior and Exterior Protection

Protecting your vehicle's interior and exterior from the sun's harmful rays is essential for maintaining its aesthetic appeal and resale value. Consider investing in a quality car cover or parking in shaded areas whenever possible to minimize sun exposure. 


Furthermore, apply a UV protectant to your dashboard, seats, and trim to prevent fading and cracking. Regular waxing and polishing can safeguard your vehicle's paint from oxidation and sun damage.

Fluid Checks To Round It All Out 

Aside from coolant, other fluids in your vehicle play crucial roles in maintaining optimal performance, especially during summer. Regularly check engine oil, transmission fluid, brake fluid, and power steering fluid levels. Mechanical problems can happen when there is a low fluid level, especially when the temperature is high.

Emergency Kit Preparation

No matter how well you care for your car, emergencies can still happen, especially when the weather is terrible. As part of your summer car care routine, assemble an emergency kit tailored to Missouri’s climate. Include essentials such as water, non-perishable snacks, a first-aid kit, jumper cables, a flashlight with extra batteries, a multipurpose tool, and a reflective vest. Stash the kit in your trunk for easy access in roadside emergencies.

Engine Air Filter Replacement If You Travel Often 

Missouri‘s dusty roads and pollen-rich air can clog up your engine air filter faster than usual, impeding airflow and reducing engine performance. Check your vehicle's maintenance schedule and replace the engine air filter as the manufacturer recommends. A clean air filter saves you money on gas and keeps your engine safe from dangerous contaminants, so it runs smoothly all summer.

Watch Those Driving Habits

Lastly, your driving habits significantly preserve your vehicle's health and safety, especially in hot weather. Avoid aggressive driving maneuvers such as sudden accelerations, hard braking, and high-speed cornering, as they can put unnecessary strain on your vehicle's components and increase fuel consumption.
