Coolant and Antifreeze Are Crucial in Hot Summer Months

June 12, 2025

Hot Summer Month = Coolant Issues

A topic that’s often overlooked but essential for your vehicle’s well-being, especially during the scorching summer months is coolant and antifreeze. Here at Automotive Magic Auto Repair and Maintenance in Kenvil, NJ, we believe in not just fixing cars but also educating our community about the finer details of car care. So, buckle up as we take you through why your engine's best friend during summer is none other than coolant (or antifreeze)!


The Role of Coolant in Summer

When the temperature outside starts climbing, your car’s engine works even harder. All that extra effort generates a lot of heat. Here's why coolant is crucial during these hot months:


Prevents Overheating

One of the primary roles of coolant is to absorb the heat from the engine and dissipate it through the radiator. When you're driving in high temperatures, your engine can become dangerously hot, leading to overheating. Overheating can cause significant damage, from warping the cylinders and pistons to blowing the head gasket, all of which are expensive repairs. Coolant ensures that the engine temperature stays within the optimal range, saving you from these costly headaches.


Lubricates the Engine Components

Coolant isn’t just about temperature regulation. It also lubricates the moving parts it comes into contact with, such as the water pump. This lubrication reduces friction, which in turn reduces wear and tear, prolonging the life of your engine components.

Protects Against Corrosion

Modern coolants contain additives that prevent corrosion and rust within the engine and the cooling system. This is particularly important during summer when the coolant is working overtime. Without these additives, the metals in your engine and radiator could corrode, leading to leaks and system failures.


Signs Your Coolant Needs Attention

Now that you know how important coolant is, it’s vital to recognize when it might be time to give it some attention. Here are a few signs that you need to check your coolant levels or that it might be time for a flush:


Rising Temperature Gauge: If your car's temperature gauge is consistently higher than normal, it could indicate low coolant levels.

Coolant Leaks:  Puddles of green, yellow, or orange fluid under your car might mean you have a coolant leak.

Sweet Smell: Coolant has a distinctive sweet smell. If you notice this inside or outside your car, it could indicate a leak.

Frequent Overheating: Regular episodes of overheating are a clear sign that your coolant system needs attention.

Regular Maintenance Tips

To keep your car running smoothly all summer long, follow these simple maintenance tips:


1. Check Coolant Levels Regularly

Make it a habit to check your coolant levels every few weeks, especially during summer. Ensure that the coolant is at the appropriate level, and top it off if necessary. Always do this when the engine is cool to avoid burns.

2. Flush Your Coolant System

Over time, coolant can become contaminated and lose its effectiveness. A coolant flush every two years or 30,000 miles can help maintain the cooling system’s efficiency. During a flush, old coolant is completely drained, the system is cleaned, and new coolant is added.


3. Inspect Hoses and Radiator

Regularly inspect your radiator and hoses for signs of wear, leaks, or cracks. The summer heat can exacerbate any existing issues, so catching them early can save you from breakdowns.


As the temperatures soar, so does the importance of maintaining your car's cooling system. Coolant (or antifreeze) is your engine's best friend, keeping it cool, lubricated, and corrosion-free. By understanding its role and ensuring regular maintenance, you can avoid the costly repairs associated with overheating.

Summer is all about adventure — beach days, weekend getaways, long road trips to places you've been dreaming of all winter. But nothing puts a damper on those big family plans faster than a surprise car issue an hour into the drive. The good news? A quick pre-trip check can go a long way toward keeping everyone safe, stress-free, and focused on the fun ahead. Whether you’re a seasoned road tripper or just heading to the grandparents’ for a long weekend, here’s a simple, smart checklist to help make sure your vehicle is ready to roll. Before You Pull Out of the Driveway, Take a Few Minutes to Check: Your Tires Tires are one of the easiest things to overlook — until something goes wrong. Make sure all four (plus the spare!) are properly inflated. Check your owner’s manual or the sticker inside the driver’s door for the right pressure. Do the “quarter test” for tread depth — stick a quarter into the tread with Washington’s head down. If you can see the top of his head, it’s time for new tires. Look for any visible cracks, bulges, or uneven wear. That kind of damage is a warning sign worth listening to. Well-maintained tires mean better handling, better gas mileage, and a whole lot less stress on the road. Windshield Wipers & Washer Fluid Is there anything more annoying than trying to see through a streaky windshield while your kids are arguing about snacks in the back? ✔️ If your wipers squeak, skip, or smear, it’s time for a new set. ✔️ Top off your washer fluid so you can clear away bugs, pollen, or sudden summer showers with ease. Visibility matters — especially when driving in unfamiliar places or late at night. All the Fluids (Yes, More Than Just Oil) Your vehicle needs more than fuel to function safely. Give these a quick look: Engine oil – clean and at the right level? Coolant – helps prevent overheating on hot summer drives Brake fluid – vital for safe stopping Transmission fluid Windshield washer fluid – yes, again! It’s worth repeating. Don’t stress if you're not sure what you’re looking at — a trusted shop can give these a once-over in minutes. Battery/Alternator Health You don’t want to find out your battery’s on its last leg in the middle of a scenic overlook. Is your car slow to start lately? That’s a sign. Check for corrosion around the terminals. If it’s more than 3 years old, it’s a good idea to have it tested before the trip. A strong alternator keeps everything running — including the air conditioning, charging ports, and navigation. Lights & Signals It's easy to miss a burnt-out bulb, but other drivers rely on your lights to predict what you're doing. Test your headlights (low and high beams), brake lights, turn signals, license plate lights, and hazard lights. Have someone help or do a quick walk-around with your lights on. It’s a fast check that makes a big safety difference, especially when traveling unfamiliar roads. Pack These — Just in Case Even with the best prep, things happen. Having these on hand keeps you ready for whatever the road throws your way: Jumper cables A portable tire inflator Tire pressure gauge Flashlight and extra batteries First aid kit Bottled water and extra snacks Charging cords Blanket or travel towel (multi-use lifesaver!) Pro Tip: Book a Pre-Trip Inspection Want total peace of mind? Bring your car over to Automotive Magic for a quick pre-trip inspection. A professional can check your brakes, alignment, belts, hoses, and everything else you might not have time (or desire) to inspect yourself. It’s fast, affordable, and worth it. We recommend scheduling your appointment a week in advance to make sure any repairs will be done in time for your trip! You’ve packed the bags, planned the route, and made a solid snack strategy — don’t let a simple car issue sideline your trip. A little preparation today means fewer surprises tomorrow and a lot more time for family fun, scenic photos, and unforgettable memories! Happy travels — and here’s to making memories (not emergency stops)!
