Just as you dress yourself in extra layers and winterize your house to protect it from the cold, your car needs extra preparation to make it through the winter as well.  But getting ready is only half the battle.  Winter driving conditions also mean driving differently.  Snow and ice need to be taken seriously and prepared for. 

When winter approaches there are some basic things you must do to make sure your vehicle remains reliable and safe.  Have maintenance service on your vehicle as often as the manufacturer recommends.  In addition:

• Have the radiator system serviced, or check the antifreeze level yourself with an antifreeze tester.  Add antifreeze, as needed.
• Replace windshield-wiper fluid with a wintertime mixture.  Also check your windshield wipers for wear and replace if needed.
• Replace any worn tires, and check the air pressure in the tires.  Also make sure your spare has air in it and that you know how to safely use your jack and lug wrench.
• A thorough cooling system check will include a leak test. This is where they put the system under pressure and visually look for leaks. Ask your mechanic to do this, in the event it is not part of his regular cooling system service.
• Make sure that all your radiator and heater hoses are also checked. If any of them show signs of cracking, rotting or softness replace them even if they're not leaking yet.
• Check all fan belts for cracks or wear. Replace if necessary.
• Make sure your heater, defroster and rear defogger are working properly.
• Have your battery and charging system checked for optimum performance. Don't take any chances here.
• Carry emergency equipment on board your vehicle, including jumper cables, flash light, extra batteries, flares, a shovel, first aid kit, basic hand tools, blankets and if at all possible a cell phone.
• During winter, keep the gas tank near full to help avoid ice in the tank and fuel lines.
