It's November and there is a chill in the air, a frosty reminder that the worst is yet to come. So here is what you need to do to prepare your car for all winter has to offer:

UNDER THE HOOD
AIR FILTER Replace according to owner's manual, more frequently in dusty conditions or when dirty. A dirty filter will lower gas mileage and hurt performance. Hold it up to the light to see the dirt on it.
POWER STEERING Groaning noises or a rough feeling when you turn the wheel mean the system needs attention. It could be low on fluid. Leak anyone?
BELTS Make sure drive belts are adjusted for proper fit and are not cracked, glazed or frayed. Check both sides of serpentine belts.
SPARK PLUGS If your car is approaching time for a tune-up, replace the spark plugs for improved starting in the cold.
PCV VALVE Replace this pollution-control device, usually located in the valve cover, at least as often as you replace the spark plugs.
HOSES Check for leaks, bulges or cracks, and make sure clamps are secure. This includes air intake hoses or ducts.
BATTERY Clean the terminals with a solution of baking soda and water. Make sure all connections are secure.
COOLING SYSTEM Check the protection using a hydrometer or test strips. Change as required. If low, add a 50/50 mixture of antifreeze and water to protect to 35 degrees below zero. You may want to flush before installing fresh antifreeze or at least every two years.
WINDSHIELD WASHER Keep your windshield-washer reservoir full using the premixed blue stuff or mix your own from concentrate.
THE EXTERIOR
WINDSHIELD-WIPER BLADES Replace worn, streaking or damaged blades. Consider installing winter blades that won't pack with snow to stay in contact with the glass.
WINDOWS Apply water repellent to windshield and all windows to keep them free of slush, salt and muck. This also makes ice easier to remove.
DOORS, HATCHES AND TRUNKS Apply silicone oil or grease to all door, hatch and trunk-lid gaskets to preserve the rubber and keep them from freezing shut.
