Engine Performance -- Have engine driveability problems (hard starts, rough idling, stalling, diminished power, etc.) corrected at a good repair shop. Cold weather will make existing problems worse. Replace dirty filters -- air, fuel, PCV, etc.
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 in the first place.
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, allow the radiator to cool down completely before removing the cap. (Newer vehicles have coolant reservoirs.) 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. But do-it-yourselfers can do routine maintenance. 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: Be sure to avoid contact with corrosive deposits and battery acid. Wear eye protection and rubber gloves. Note too that removal of cables can cause damage or loss of data/codes on some newer vehicles so refer to your manual for instructions.
Lights -- Inspect all lights and bulbs; replace burned out bulbs; periodically clean road grime from all lenses with a moistened cloth or towel. 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.
The National Institute for Automotive Service Excellence (ASE) was founded in 1972 as a non-profit, independent organization dedicated to improving the quality of automotive service and repair through the voluntary testing and certification of automotive professionals. ASE-certified technicians wear blue and white ASE shoulder insignia and carry credentials listing their exact area(s) of certification, while their employers often display the blue and white ASE sign. They can be found at all types of repair facilities from dealerships to independent garages and franchises. Visit www.ase.com for more information.
