Keep battery backup. It takes more electrical power to start a car in cold weather, yet those chilly temperatures also drastically reduce the battery's cranking power. To compensate for the increased need and reduced output, keep a good set of jumper cables or a portable power pack in the trunk.
Check climate controls. Make sure the heater and front and rear defrosters are working properly. If it takes more than a few minutes to feel or see a change, take the car in for service. In addition, take the extra time in the mornings to wait for the windows to defrost completely.
Replace wiper blades. Windshield wiper blades should be replaced every six months to a year, depending on the climate (although most drivers only replace them once every few years). Well-made, effective blades are essential for maximum visibility in bad weather.
Change the oil. Consider switching to a different grade of oil to help protect your engine in the cold. Base your decision on the lowest temperature you expect to encounter; for example, use 0W-30 in climates where the temperature drops below zero. While there are many differing opinions about which grades of oil to use, a good rule of thumb is to choose a multi-grade with the narrowest range of viscosity possible (meaning, the smallest difference between the low number and the high number on the label). Make sure to check the owner's manual for specific guidelines for your car.
Check filters, hoses, fluids. Inspect hoses to make sure they're properly connected and free of damage or leaks. Also check the oil, gas, and air filters. Coolant should be changed every two years (five years for extended-life coolant). Also check the radiator or coolant tank pressure cap.
Keep a full tank. A sudden storm or unexpected car problem could leave a driver stranded for hours. Get in the habit of filling the tank when it reaches the half-full mark to ensure there will be enough fuel to run the heater for a long period of time in case of emergency.A recent AAA survey names some of the most common -- and potentially dangerous -- auto ailments. Fortunately, all of these maladies can be prevented with a little care and attention. Here are the top culprits:
5. Worn-out windshield wiper blades. Old, torn, or cracked wiper blades can greatly reduce visibility when driving in bad weather. Experts recommend changing blades at least once a year, or when streaking begins.
4. Low or dirty oil. Low oil levels can cause overheating and severe engine damage, since there is not enough fluid to lubricate all of the engine's moving parts. Dirty oil contains debris and deposits, which increases engine wear. Check oil levels at least once a month and perform regular oil changes according to the manufacturer's recommendations. Many newer cars come equipped with sensors that alert drivers when the oil needs topping off or changing, but it's not a bad idea to check manually, too, when possible.
3. Worn tires. Road tires should have a minimum of 3/32" tread depth. A good way to check: Insert a penny into the tread groove with Lincoln's head turned upside down. If all of Lincoln's head is visible, it's time to get new tires. If only one or two tires need replacing, make sure the replacement tires match the size, model, and tread pattern of the existing tires on the car.
2. Clogged air filter. Decreased airflow through the filter will rob a car of horsepower and decrease gas mileage. Check the car's owner's manual to find the appropriate replacement interval. On many cars, changing the air filter is a pretty simple, do-it-yourself job.
1. Incorrect tire pressure Proper tire pressure ensures road safety, preserves tire tread life, and helps to maximize fuel economy. Tires lose air naturally over time, but they can also lose large quantities of air suddenly when hitting a pothole or a curb. The National Highway Traffic Safety Administration (NHTSA) recommends checking the air pressure on each tire at least once a month. To ensure accuracy, measure when the tires are cold.
Other problems mentioned in the survey include low transmission fluid and engine coolant levels, worn or corroded battery cables, clamps, and terminals, and low windshield washer fluid levels. Survey results are based on inspections conducted on 6,082 vehicles by 25 different AAA clubs nationwide.
