Is Your Car Ready for Summer? Here’s What Every Driver Should Check Before the Heat Hits

Summer in Clarksville is no joke. We’re talking triple-digit heat indexes, stop-and-go traffic on Wilma Rudolph, and weekend road trips to the lake. Every summer, our team at A&R Complete Auto Care sees the same thing: cars that were running fine all spring start breaking down right when drivers need them most. 

The good news? Most of those breakdowns are completely preventable. Here’s exactly what you should check, and why it matters, before the heat hits hard. 

1. Air Conditioning System 

This one’s obvious, but it’s also the most overlooked until it’s 95 degrees and your AC is blowing warm air. 

Your AC system relies on refrigerant to cool the air inside your cabin. Over time, refrigerant levels drop,  and even a small leak can cause the system to lose efficiency fast. Before summer peaks, have your AC inspected and recharged if needed. Our technicians can also check the compressor, condenser, and cabin air filter, all of which directly affect how well your system performs when temps spike. 

What to watch for: AC that takes too long to cool down, weak airflow, or a musty smell when the system kicks on. 



2. Coolant (Antifreeze) 

Your engine generates enormous heat, and in summer, it’s working harder than ever. Coolant is what keeps your engine from overheating. If your coolant is low, old, or contaminated, you’re at real risk of an overheated engine, which can mean thousands of dollars in damage. 

We recommend checking both the coolant level and the condition of the fluid. Old coolant loses its ability to regulate temperature effectively. A coolant flush and refill is inexpensive protection against a very costly repair. 

What to watch for: Temperature gauge running high, sweet smell coming from the engine, or visible fluid under the car. 

3. Tires 

Heat is hard on tires. Hot pavement dramatically increases the risk of a blowout, especially if your tires are underinflated, worn, or aging. In fact, tire pressure actually increases as temperatures rise, so a tire that was fine in March may be overinflated by July. 

Check your tread depth and look for uneven wear, cracks in the sidewall, or bulges. And don’t forget to check your spare. A blowout on I-24 is the last place you want to discover your spare is flat. 

What to watch for: Tread depth below 2/32”, visible cracking or bulging, or pressure that’s consistently off. 

4. Battery 

Most people associate dead batteries with winter, but summer heat is actually harder on your battery than cold weather. Heat accelerates internal battery corrosion and evaporates the fluid inside, significantly shortening battery life. 

If your battery is more than three years old, have it tested before summer. A quick load test tells us whether your battery is holding a charge the way it should. Catching a weak battery before it fails completely is a $0 fix compared to a jump start or tow on a 100-degree day. 

What to watch for: Slow engine crank when starting, dashboard warning light, or corrosion visible on the battery terminals. 

5. Oil and Oil Change Interval 

Motor oil lubricates and also helps cool your engine. In extreme heat, thinner or degraded oil has a harder time doing its job. Make sure you’re not overdue for an oil change, and consider whether your oil viscosity is appropriate for summer driving. 

If you do a lot of stop-and-go driving in Clarksville traffic or plan on towing this summer, your engine is working extra hard, and staying current on oil changes matters even more. 

What to watch for: Dark, gritty oil on the dipstick, oil change reminder light, or more than 5,000 miles since your last change (depending on your vehicle and oil type). 

6. Belts and Hoses 

Heat accelerates the breakdown of rubber components. Belts and hoses that are cracked, brittle, or swollen are far more likely to fail when your engine is running hot. A snapped serpentine belt or a burst coolant hose doesn’t just leave you stranded; it can cause serious engine damage. 

A visual inspection during a routine service can catch these before they become an emergency. It’s one of the simplest and most overlooked things we check. 

What to watch for: Visible cracking, fraying, or softness in hoses and belts. Squealing sounds at startup. 

7. Brakes 

Summer driving often means more road trips, more traffic, and more braking. If your brakes are already marginal, added heat and use will accelerate wear quickly.

 

Have your brake pads and rotors inspected, especially if you’ve noticed any squealing, grinding, or a pulling sensation when you brake. Brakes aren’t an area to defer, both for your safety and the safety of everyone around you. 

What to watch for: Squealing or grinding when braking, vibration in the pedal, or a car that pulls to one side when stopping.
