From a mechanical aspect, winter conditions—wet, cold, and icy weather—present the greatest challenge to your vehicle’s operating efficiency. Since these conditions cannot be avoided, prepare for winter by performing a complete vehicle checkup in the fall. Our valued partner AAA suggests that you check, or have your mechanic check, the following items:
Battery – Have your alternator or generator, voltage regulator, and drive belts checked also.
Ignition System – Damaged ignition wires, a cracked distributor cap, or worn spark plugs can make starting difficult or may cause a sudden vehicle breakdown.
Lights – Make sure all your lights and lenses are clean and functioning properly. Grime on headlight lenses reduces their effectiveness by as much as 90%.
Have your brakes checked regularly and do not delay any necessary maintenance or repairs.
Make certain your tires are properly inflated and in good condition. While it is best to purchase tires in sets of four, if you only purchase two, mount them on the rear wheels.
Have a mechanic check your exhaust system for leaks in order to minimize the chances of carbon monoxide poisoning. If your car is stuck in the snow and you have the engine running, open a window slightly and clear snow away from the exhaust pipe.
Heating and Cooling System
Make sure your vehicle’s cooling system contains enough antifreeze to prevent freezing in cold weather. Keep the mixture fresh by changing it regularly and having the entire system checked for leaks.
Windshield Wipers, Washer, Glass, and Vehicle Exterior
Clean windows offer optimal visibility. An antifreeze washer solvent should be used in the water reservoir bottle.
It is also recommended that you have a winter driving kit in your vehicle. The following items will be invaluable should an emergency develop:
Bag of abrasive material (sand, salt, or cat litter)
Small snow shovel, snow brush, and ice scraper
Flashlight and extra batteries
Window-washing solvent; cloth or paper towels
Booster cables; warning flares or triangles
Gloves or mittens and blanket
