Fuel -- Put a bottle of fuel de-icer in your tank once a month to help keep moisture from freezing in the fuel line. Note, too, that a gas tank that’s kept filled helps prevent moisture from forming.
Oil -- Change your oil and oil filter as specified in your manual -- more often (every 3,000 miles or so) if your driving is mostly stop-and-go or consists of frequent short trips.
Cooling System -- The cooling system should be flushed and refilled as recommended. The level, condition, and concentration of the coolant should be checked periodically. (A 50/50 mix of anti-freeze and water is usually recommended.) If you’re doing your own work, never remove the radiator cap until the engine has thoroughly cooled! The tightness and condition of drive belts, clamps, and hoses should be checked by a certified auto technician.
Heater/Defroster -- The heater and defroster must be in good working condition for passenger comfort and driver visibility.
Windshield Wipers -- Replace old blades. If your climate is harsh, purchase rubber-clad (winter) blades to fight ice build-up. Stock up on windshield washer solvent; you’ll be surprised how much you use. Carry an ice-scraper.
Battery -- The only accurate way to detect a weak battery is with professional equipment. Routine care: Scrape away corrosion from posts and cable connections; clean all surfaces; re-tighten all connections. If battery caps are removable, check fluid level monthly.
A word of caution: Removal of cables can cause damage or loss of data/codes on some newer vehicles. Check your manual. Be sure to avoid contact with corrosive deposits and battery acid. Wear eye protection and rubber gloves.
Lights -- Inspect all lights and bulbs; replace burned out bulbs; periodically clean road grime from all lenses. To prevent scratching, never use a dry rag.
Exhaust System -- Your vehicle should be placed on a lift and the exhaust system examined for leaks. The trunk and floorboards should be inspected for small holes. Exhaust fumes can be deadly.
Tires -- Worn tires will be of little use in winter weather. Examine tires for remaining tread life, uneven wearing, and cupping; check the sidewalls for cuts and nicks. Check tire pressure once a month. Let the tires “cool down” before checking the pressure. Rotate as recommended. Don’t forget your spare, and be sure the jack is in good condition.
Emergencies -- Carry gloves, boots, blankets, flares, a small shovel, sand or kitty litter, tire chains, a flashlight, and a cell phone. Put a few “high-energy” snacks in your glove box.
