How to Take Care of your Car in the Heat

Summer is just around the corner…Is your vehicle prepared to “Take the Heat”?

When outside temperatures rise, vehicles feel it too. High temps can destroy car batteries, stress their cooling systems, and wear on their tires. As a precaution, vehicle owners should periodically check these components to help avoid breakdowns and car problems.

Battery Safety & Precautions:

Excessive heat and overcharging shorten the life of a battery. Heat causes battery fluid to evaporate, which then damages the internal structure of the battery. A malfunctioning component in the charging system, usually the voltage regulator, allows too high a charging rate, which will eventually destroy a battery.

To get the most life out of a battery, the council recommends having the electrical system checked to make sure it is charging at the correct rate. If your car’s battery is the type that needs to be topped off, check it often, especially in hot weather and add distilled water if necessary. Keep the top of the battery clean. Dirt can become a conductor, which drains battery power. If corrosion accumulates on battery terminals, it becomes an insulator and inhibits the current flow.

Cooling Systems and You:

The cooling system also works harder during hot temperatures to prevent overheating of the engine. To keep the cooling system working effectively, the coolant and distilled water mixture for a vehicle’s radiator should be 50:50. As a precaution, never open a hot radiator cap when checking the coolant level in the reservoir.

As a rule of thumb, the coolant should be changed annually on most vehicles. This will keep the cooling system fresh and clean inside, which helps prevent corrosion and assures that the coolant has the proper boiling point and protection. A pressure test, thermostat test, a cooling fan test and a visual inspection for leaks and corrosion should also be done annually. Hoses and drive belts should be checked for cracks, bulges or frayed edges.

The radiator should be kept clean by periodically using a garden hose and a soft brush to carefully remove bugs, dirt and debris.

Tire Life and Safety:

Tires also need special care in warmer weather as high temperatures put added stress on them. To maximize tire life and safety, check the tire condition and inflation pressure monthly, and have the tires rotated every 6,000 miles. Summer heat will cause the pressure within a tire to rise, therefore, it’s important to check the pressure when tires are cold. The owner’s manual includes the recommended air pressure for your vehicle’s tires.

“It takes very little time and money to make sure your car runs properly during summer, and although breakdowns happen, they can definitely be minimized by taking a few extra preventive maintenance steps,” said Rich White, executive director, Car Care Council.

Horizon Auto Center would like to invite anyone who does not have the time to check these components on their own to stop by our shop and allow us to perform a courtesy inspection. We want to make sure that everyone stays safe, happy, and cool during this HOT Texas Summer.
