• Cooling systems protect engines from overheating and should be flushed periodically, as recommended by the vehicle manufacturer.
• Between flushes, make sure the coolant is filled to the proper level 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.
• Cution — Never remove the radiator cap when the engine is hot. Boiling coolant under pressure could cause serious burns.
• Rubber cooling system components are susceptible to heat-related deterioration, so periodically inspect hoses and drive belts for cracking, soft spots or other signs of poor condition.
Just as driving on underinflated tires is dangerous, over-inflated tires can cause uneven wear, reduce vehicle handling and make tires susceptible to road hazard damage.
• Check tire pressure often as tires lose pressure naturally (typically 1-3 psi per month) because a tire’s sidewall is permeable.
• Low tire pressure results in poor handling and braking, reduced gas mileage and excessive wear. So be sure to check your car’s tire pressure at least once a month — especially before a long trip.
• Check the tread depth. A tire’s ability to stop within a safe distance becomes compromised when its tread depth reaches 4/32 inch. An easy way to determine if a tire is worn out is to place an upside-down quarter (not a penny) in a tire tread. If you can see the top of Washington’s head, it’s time to replace the tire.
• Know the tire’s age. As a tire ages, its rubber becomes hard and brittle, losing elasticity and strength. Therefore, the older a tire, the higher the risk for failure. The age of your tire can be found by checking the last four DOT numbers stamped on a tire’s sidewall; for example, 0419 means the tire was manufactured in the fourth week of 2019. AAA recommends replacing any tire that’s six years old or older.
For more tire safety tips, drivers can visit AAA.com/TireTips. Even with preventive maintenance, summer breakdowns can still occur, so AAA recommends drivers have a well-stocked emergency kit in their cars. 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 maintenance tasks needed to prepare a car for extreme summer heat are relatively simple and can be performed by the average driver, but some are best left to a trained automotive technician. AAA offers a free public service to assist motorists seeking a qualified auto repair facility.
AAAApproved Auto Repair facilities must meet stringent professional standards and maintain an ongoing customer satisfaction rating of 90 percent or better.
