Getting Your Vehicle Ready for Winter
Mechanical failure, an inconvenience any time it occurs, can be deadly in the winter. Preventive maintenance is a must. Besides, a well maintained vehicle is more enjoyable to drive, will last longer, and could command a higher resale price.
Some of the following tips can be performed by any do-it-yourselfer; others require the skilled hands of an auto technician.
First things first: Read your owner's manual and follow the manufacturer's recommended service schedules.
Engine Performance: Get engine problems (hard starts, rough idling, stalling, diminished power, etc.) corrected at a good repair shop. Cold weather makes 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 that a gas tank which is kept filled helps keep moisture from forming.
Oil: Change your oil and oil filter as specified in your manual--more often (every 3,000 miles) if your driving is mostly stop-and-go or consists of frequent short trips.
Cooling Systems: The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of the coolant should be checked periodically. (A 50/50 mix of anti- freeze and water is usually recommended.)
Do-it-yourselfer: 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 pro.
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.
Heater/Defroster: The heater and defroster must be in good working condition for passenger comfort and driver visibility.
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.
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 floor boards 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 pressures 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.
Emergency Gear: Carry gloves, boots, blankets, flares, a small shovel, sand or kitty litter, tire chains, and a flash light. Put a few "high-energy" snacks in your glove box.
