Summer is approaching, and with that, many will be gearing up for long drives and adventurous road trips. For a stress-free summer drive, it is essential to take proper care of your car. Heat, dusty roads, and constant driving can slowly wear it out and put it at risk for breaking down at any moment.
Before you hit the road, here's a smarter idea. If you're moving across the country or sending a car to a family member this summer, why put all those hot highway miles on your vehicle? Let us ship your car with our nationwide car shipping service. Skip the drive, avoid the wear and tear, and let us handle the transport while you relax.
Higher temperatures put additional stress on critical parts of the vehicle, including the engine, battery, tires, and fluids. In simple terms, overheating is one of the leading reasons why many cars suddenly give up in summer. While you are on your way to a fun trip and don’t want an interruption from a sudden engine malfunction or a tire blowout, here are some easy tips to follow. These small steps go a long way in ensuring your vehicle’s safety.
Your vehicle’s cooling system works overtime in summer heat. If coolant/anti-freeze levels are low, it can quickly lead to overheating, especially when you are driving through long highways or steep grades. Negligence over time can lead to costly damage, which could be prevented with a little care.
To take care of it, check the coolant reservoir when the engine cools down, and top it off if needed. If you're constantly adding coolant, but the level seems too low, have a mechanic check for leaks and other potential issues.
Along with regular checks of coolant level, also watch the radiator, hoses, and belts for cracks or leaks. Even a small issue can escalate into a major breakdown if ignored.
Hot weather affects tire pressure more than most drivers even realize. When temperatures go higher, the air inside your tires expands. That can lead to overinflation, or worse, a blowout. Overinflated tires wear unevenly. On the flip side, underinflated tires overheat faster. Neither one is good.
So check the tire pressure regularly. Not sure what it should be? Look for a sticker inside your driver's door jamb, doorpost, glove box, or fuel door. It'll tell you the right PSI. And while you're taking care of tires, take a look at their tread depth as well. Worn tires and summer rain don't work well.
What to check:
Proper tire pressure — Follow the manufacturer's manual as the recommended PSI level can differ for most vehicles; however commonly remains between 30-35.
Signs of uneven wear or damage — If you notice uneven wear or damage on wheels, it may be a call for wheel alignment.
Tread depth — Insert a penny upside down into the tread. If you can see the top of Abraham Lincoln’s head, your tires are too worn for safe driving.
Don’t forget your spare tire. Also, it’s a good idea to rotate tires to extend their life span. For a more worry-free summer, it’s ideal to change winter tires.
Don't wait until the first heatwave to find out your AC is broken. Turn it on. Does cold air come out? Do you feel any strange smells or noises coming from the AC? If yes, there may be an issue.
If the AC feels weak or warm, you might be low on refrigerant, or there may be a leak. Get it serviced before you're stuck sweating in traffic, because a working AC system isn’t just about comfort; it helps you stay alert and focused on the road.
In case of malfunctioning, the AC may need a refrigerant recharge, leak inspection, and filter replacement. Testing it early ensures you enjoy a comfortable drive through the heat of summer.
Many people associate battery issues with winter, but summer heat can be just as damaging. Heat speeds up battery corrosion and fluid evaporation, which is why a battery that struggled through winter might die completely in summer. Proper battery care is essential in hot weather, as high temperatures can shorten its lifespan.
Ensure tight connections. Check the terminals for white or blue crusty buildup. Clean it off with a wire brush. If the battery is over three years old, have it tested, or better yet, replace it.
Windshield wipers work a lot through the winter, keeping the snow, road salt, sleet, and rain off your windshield. When transitioning into summer, inspect their condition and replace them if necessary.
Dried-out or unchecked wiper blades will streak and skip. It will reduce visibility when you need it most. It’s recommended to replace them every six months or as soon as you feel they are not cleaning the windshield evenly. It's a cheap fix that keeps you ready for a sudden summer thunderstorm.
Summer often means longer drives, which puts extra pressure on the car’s braking system. While driving, listen and feel for squealing or grinding noises, reduced braking performance, and vibrations. If you feel any of them, it’s time for a maintenance check.
Also, inspect belts and hoses as they crack faster in extreme heat. A snapped serpentine belt or burst radiator hose will leave you stranded. Also, look for cracks, fraying, soft spots, or bulges. If any of them look worn, replace them before they fail.
Heat causes fluids to evaporate or thin out. Checking coolant is mandatory, but beyond coolant, also check:
Oil — Heat breaks down oil faster.
Brake fluid — Low fluid affects stopping distance.
Power steering fluid — Keeps the steering smooth.
Windshield washer fluid — Summer bugs and dust mean you'll use more.
If the air filter is clogged, it requires more force on the engine to work harder. Ultimately, it reduces performance and fuel efficiency. Among various reasons, dust, pollen, and debris are commonly seen as some causes to clog the air filter. For a better airflow, improved fuel economy, and reduced engine strain, regularly unclogging air filters is a vital step.
Engine oil breaks down comparatively faster in summer heat than in winter cold. If you're due for an oil change, don't prolong the wait. Change it as soon as possible. Fresh oil keeps your engine cooler by reducing friction. It's the single most important thing you can do for engine health.
The summer sun throws intense heat. UV rays fade paint and damage clear coats over time.
A good wax job can work as a shield. It adds a layer of protection and makes it easier to wash off summer bugs, dust, and tree sap. No matter whether you do it yourself or just pay an expert for the job, either way, your car will be saved.
And here's something else to think about. Even with the best maintenance, unexpected breakdowns can still happen. That's why having a Car protection plan matters. Learn more in our blog: Reasons to Get an Extended Car Warranty Protection Plan.
If you've done all the summer prep but still want extra protection, paint protection film might be the thing you are looking for. PPF is a clear wrap that goes over your vehicle's paint to shield against dust, dirt, road debris, and UV rays. It's not very cheap and is mostly used on new, luxury, classic, or exotic cars, but if you want to protect your car, it’s the investment you will never regret. It can be applied to the whole vehicle or just high-risk areas like the front bumper and hood. It’s easily removable, at any time, but can last up to 10 years. After that, it may turn yellow, but the original paint underneath stays looking showroom-ready.
Enjoying road trips in summer is exciting, but breaking down your car is intimidating. But that’s not something that can be prevented. By following the instructions in this article, you can not only enjoy a smooth summer ride, but also extend your vehicle’s life span and maintain its resale value.
