Battery and Charging System – Have the battery and charging system tested by a trained technician. A fully charged battery in good condition is required to start an engine in cold weather. AAA members can request a visit from a AAA Mobile Battery Service technician who will test their battery and replace it on-site, if necessary. AAA Approved Auto Repair shops can also test and replace weak batteries.
Battery Cables and Terminals – Make sure the battery terminals and cable ends are free from corrosion and the connections are tight.
Drive Belts – Inspect the underside of accessory drive belts for cracks or fraying. Many newer multi-rib “serpentine” belts are made of materials that do not show obvious signs of wear; replace these belts at 60,000-mile intervals.
Engine Hoses – Inspect cooling system hoses for leaks, cracks or loose clamps. Also, squeeze the hoses and replace any that are brittle or have an excessively spongy feeling.
Tire Type and Tread – In areas with heavy winter weather, installing snow tires on all four wheels will provide the best winter traction. All-season tires work well in light-to -moderate snow conditions provided they have adequate tread depth. Replace any tire that has less than 3/32-inches of tread. Uneven tire wear can indicate alignment, wheel balance or suspension problems that must be addressed to prevent further tire damage.
Tire Pressure – Check tire inflation pressure on all four tires and the spare more frequently in fall and winter. As the average temperature drops, so will tire pressures – typically by one PSI for every 10 degrees Fahrenheit. Proper tire pressure levels can be found in the owner’s manual or on a sticker typically located on the driver’s side door jamb.
