Tip 7: Replace Windshield Wipers and Wiper Fluid
Low visibility can make driving in cold weather extremely dangerous, so it’s important to make sure the wiper blades are up to par. Your wiper blades are made out of rubber, and with time they’ll crack, split and deteriorate. It’s suggested that you replace your windshield wipers every six to 12 months. Keeping your wiper fluid filled up is also a plus, as fluid can assist in breaking up snow and ice on the windshield.
Tip 6: Check Your Defrosting and Heating Units
When our windshields fog up in the winter, it’s because moisture from inside the car condenses on the glass and makes it very difficult to see. Water vapor coming in from an open window — or even from your own breathing — can fog up a window. Defrosters solve this problem by blowing warm, dry air over the glass. If you’re sure your defroster unit is functioning properly but there’s still a problem with too much fogging, have your car checked for air leaks around the doors and windows bringing in extra moisture.
It’s also important to stay warm and comfortable while driving, since shivering makes it difficult to steer or pay attention to the road. If your heater isn’t working, you may have a faulty heater coil. Although heater coils are expensive to replace, it will be worth it during cold winter mornings if you don’t want to freeze behind the wheel.
Tip 5: Keep Your Fuel Tank Full
Do you ever let your gas tank run on fumes until the very last moment, only to fill it up with about $15 worth of gas? Although it’s never a great idea to do this any time of the year because you run the risk of getting stranded, the damage you might inflict on your car with a near-empty tank during winter is much worse. Cold and constantly shifting temperatures can cause condensation to form on the walls of a gas tank in the red, and soon water will drip down and into the gas. It will eventually sink to the bottom, since water is heavier than gas, which is bad news — if water finds its way into the fuel lines, it will freeze up, blocking any flow of gas to the engine and effectively halting your travel plans. Any repairs that have to be made can be costly, too, so despite gas prices, keeping your tank full will help both your car and your wallet.
Tip 4: Put in the Right Amount of Antifreeze
Antifreeze protects your engine from both freezing in cold weather and heating up on hot days, and it also cuts back on corrosion. It’s important to keep equal parts antifreeze and water in your radiator — a 50:50 ratio is considered the norm and will keep fluids from freezing at temperatures as low as -34 degrees Fahrenheit. Fortunately, you won’t have to stand over your engine with a measuring cup — you can buy pre-mixed bottles of antifreeze and water at gas stations. If you don’t pay attention to the amount of antifreeze, the coolant can freeze, and the engine will get extremely hot. Chances are you’ll blow a gasket or two, and the cost of replacing them with labor can be expensive.
Check Your Oil
Oil lubricates the metal surfaces of your engine and stops them from grinding together and causing a lot of damage. The viscosity — or thickness — of the oil greatly affects your engine’s performance. If the oil is too thick, it will flow too slowly between parts and your engine will get too hot. In the winter time, cold temperatures cause oil to thicken, but you can overcome this problem by filling your engine with an oil of a lower viscosity. Your owner’s manual should tell you the ideal type of oil you should use, and it also might specifically suggest a thinner oil type depending on the season. Remember, most technicians recommend that you change your oil every 3,000 miles or once every three months.
