Over at Smart Buy Auto, mechanics have been slammed with hot car problems.
Among them, dirty and damaged radiators.
"You can see where somebody has taken a car wash and when they wash the front of their car, they bend these fins over, that's a restriction for the air flow," said Doug Smart.
"Today's radiators are made out of plastic and they don't take the heat like older vehicles will because they were made out of brass and aluminum. So what happens is the radiator gets hot and cracks and you will need to repair or replace it to keep your automobile cool."
Here is an edited press release from AAA:
AAA recommends drivers address five key areas to help their vehicle safely 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.
Another potential summer problem is faster evaporation of the battery fluid, leading to corrosion on terminals and connections. Clean any corrosive build up from the battery terminals and cable clamps, and ensure the clamps are tight enough that they will not move.
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, 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, and 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. Older coolants used to require changing every two years or 24,000 miles, but most modern formulations are good for at least five years and 50,000 miles. 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.
Rubber cooing system components also are susceptible to deterioration caused by extreme heat. Inspect hoses and drive belts for cracking, soft spots or other signs of poor condition. Worn parts are more susceptible to failure in hot conditions and should be replaced.
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.
More than half the vehicles on the road were found to have at least one under-inflated tire, according to the Rubber Manufacturers Association, and 85 percent of motorists do not know how to properly inflate their tires.
