Car Care Survival Tips From AAA

VIRGINIA BEACH, VA (May 28, 2019) – With temperatures continuing to soar into this week, AAA Tidewater Virginia issued a heat advisory to motorists regarding the threat that extreme temperatures pose on motor vehicles. “High heat can cause auto parts to fail and leave motorists stranded. AAA advises motorists to take preventive measures during extended periods of very high heat like this week,” said Georjeane Blumling, Vice President of Public Affairs for AAA Tidewater Virginia. “With each day of high heat, the number of calls to AAA for emergency roadside assistance increases dramatically. Requests for battery assistance significantly increase when the thermometer rises into the upper 90’s.”

 

AAA recommends drivers address five key areas to help their vehicle survive high summer temperatures:

 

1.    Heat Can Zap the Life from Batteries

Most drivers think battery problems occur primarily in winter, but summer heat can negatively impact your car’s battery even more than the bitter cold of winter. Heat and vibration are a battery’s two worst enemies leading to internal breakdown and eventual failure. While drivers cannot do much about the heat, they can make sure their battery is securely mounted in place to minimize vibration.

 

If a car’s battery is more than three years old, it’s a good idea to have it tested by a trained technician to determine how much longer it will last. This test can be performed at any AAA Approved Auto Repair facility, AAA Car Care Center, or AAA members can request a AAA Mobile Battery Service technician come to them and test their battery free of charge. Should the battery need replacement, the technician can usually replace it on location. For more information on the AAA Mobile Battery Service visit AAA.com/Battery.

 

2.    Keep Your Engine Cool

Automobile engines work extra hard in the summer. It is the cooling system’s job to protect the engine from overheating. In addition, additives in the coolant protect the radiator and internal engine components against wear and corrosion. Without proper cooling system maintenance the odds of long term engine damage, and a summer time boil over, definitely increase.

 

Over time, engine coolant becomes contaminated and its protective additives are depleted. That’s why the system should be flushed and the coolant replaced periodically as recommended by the vehicle manufacturer. See the owner’s manual or maintenance booklet to determine the service interval appropriate for a vehicle.

 

Between flushes, make sure the coolant is filled to the proper levels by checking the overflow reservoir. If necessary, top off the reservoir with a 50/50 mix of water and the coolant type specified by the vehicle manufacturer. CAUTION! – Never remove the radiator cap when the engine is hot – boiling coolant under pressure could cause serious burns.

 

3.    Avoid Excessive Heat Where the Rubber Meets the Road

Driving on under-inflated tires not only affects the handling and braking of a vehicle, it also can cause tires to overheat and increase the likelihood of a blowout. This problem becomes even more of a concern when road temperatures are extremely high.

 

Tires should be checked when the car has not been driven recently, and they should be inflated to the pressure recommended by the vehicle manufacturer—not the number molded into the tire sidewall. Recommended tire pressures can be found in the owner’s manual or on a sticker normally located on the driver’s door jamb. Some vehicles use different pressures for the front and rear tires.

 

While checking the tire pressures—including the spare—drivers also should inspect the tire treads for adequate depth and any signs of uneven wear that might indicate a suspension or alignment problem. 

 

4.    Cars Need Fluids during Extreme Heat Too

Engine fluids are essential to keeping a vehicle running smoothly. Most fluids not only lubricate, they also serve as coolants by helping carry heat away from critical components. When fluid levels are low, this cooling effect is reduced, and the possibility of overheating increases. Drivers should check all vehicle fluids including motor oil, transmission fluid, power steering fluid, and brake fluid to ensure they are filled to the appropriate levels. If any fluids need to be topped off, be sure to use the type of fluid specified in the owner’s manual.

 

5.    Cool Passengers are Happy Passengers

Maintaining a comfortable driving environment reduces fatigue, which can play an important part in driver alertness and vehicle safety. During extreme summer heat, a properly operating air conditioning system can be more than just a pleasant convenience. If a car’s air conditioning is not maintaining the interior temperature as well as it did in the past, it may mean the refrigerant level is low or there is another problem. Have the air conditioning system checked by a certified technician.

 

Many automotive climate control systems today are equipped with a cabin filter that prevents outside debris from entering. If present, this filter should be inspected and replaced as needed to ensure maximum airflow and cooling during the summer months.

 

Just in Case….Be Prepared for Summer Breakdowns

Even with proper preventive maintenance, summer breakdowns can still occur, so AAA recommends every driver have a well-stocked emergency kit in their vehicle. The kit should include water, non-perishable food items, jumper cables, a flashlight with extra batteries, road flares or an emergency beacon, basic hand tools, and a first aid kit.

 

Many of the maintenance tasks to prepare a car for extreme summer heat are relatively simple. These tasks can be performed by the average driver; but some are best left to a trained automotive technician. As a public service, AAA Tidewater Virginia offers a free “AAA Trip Check” where the vehicle basic systems are examined before a road trip.  For more information or to set up an appointment and a certified AAA Car Care Center, motorists can call 757-963-1222 or online at AAA.com.
