Preparing Your Car for Summer
As the summer season approaches, it’s essential to prepare your car for the hot weather ahead. Here are some tips to help you get your car ready for the summer:
- Check your car’s battery: High temperatures can affect your car’s battery, so make sure to check the battery terminals for corrosion and clean them if necessary. Also, consider getting a battery test to ensure it’s in good condition.
- Inspect your tire pressure: Proper tire pressure can improve your car’s fuel efficiency and handling. Check your tire pressure at least once a month and adjust it according to the manufacturer’s recommendations.
- Check your air conditioning system: Make sure your car’s air conditioning system is working properly to keep you cool during the hot summer months. If it’s not blowing cold air, consider getting it serviced or replaced.
- Check your cooling system: Your car’s cooling system is crucial in preventing engine overheating. Check the coolant level and top it up if necessary. Also, inspect the radiator and hoses for any signs of leaks or damage.
- Check your brake fluid: Brake fluid can become less effective in high temperatures, so make sure to check the brake fluid level and top it up if necessary.
By following these tips, you can help ensure your car is ready for the summer heat and reduce the risk of breakdowns.

Car AC Not Working in Summer
There’s nothing worse than stepping into your car on a 90° day and realizing your AC isn’t working. Sudden temperature changes caused by the air conditioner can lead to stress cracks on the windshield, especially when transitioning from a hot environment to an air-conditioned setting.
Why it happens:
- Low refrigerant
- Clogged cabin air filter
- Faulty compressor
How to prevent it:
- Run your AC regularly, even in spring, to keep it active
- Have your system inspected before the heat hits
- Replace your cabin filter annually
Let our technicians perform an AC check and recharge to keep you cool all summer.
Tire Blowouts in Hot Weather
Tire blowouts are more likely in summer due to increased road temperatures and pressure buildup. Hot air can increase the stress on tires, leading to blowouts.
Why it happens:
- Overinflated or worn-out tires
- Driving on hot pavement for long stretches
How to prevent it:
- Check tire pressure weekly (including the spare)
- Keep tires inflated to the recommended PSI—not higher
- Inspect for cracking or bald tread

Battery Failure in Summer Heat
People often associate dead batteries with winter, but battery failure in summer heat is just as common—if not more so. High temperatures can significantly impact the performance and lifespan of car batteries, including both absorbent glass mat (AGM) batteries and flooded batteries. The heat causes battery fluid to evaporate, leading to a decrease in the car battery's efficiency and an increase in corrosion on the terminals. This can severely affect a car's battery, making regular inspections and maintenance crucial.
Why it happens:
- Heat causes battery fluid to evaporate
- Corrosion builds up on terminals
How to prevent it:
- Inspect terminals and clean off corrosion
- Have your battery tested—especially if it’s 3+ years old
- Park in shaded or covered areas when possible
A quick battery test at Kunes Buick GMC of Stoughton can help you avoid getting stranded.
Car Fluid Issues in Summer
Fluids break down faster in high temperatures, affecting your vehicle’s performance and longevity.
Regular inspections of the brake system are crucial, as heat can negatively impact braking efficiency. Ensure the brake fluid, pads, and rotors are maintained for safe and effective braking performance.
Fluids to check:
- Engine oil (consider synthetic for better heat tolerance)
- Transmission fluid
- Brake fluid
- Power steering fluid
- Windshield washer fluid (for bug removal)
How to prevent issues:
- Follow your manufacturer’s maintenance schedule
- Top off or flush fluids before summer road trips
- Look for leaks and discoloration

Tire Pressure Fluctuations
Temperature spikes can cause sudden changes in tire pressure, leading to reduced traction or wear.
How to handle it:
- Monitor tire pressure early in the morning
