Winterize Your Vehicle
Check or have a mechanic check the following items on your car:
Antifreeze levels - ensure they are sufficient to avoid freezing.
Battery and ignition system - should be in top condition and battery terminals should be clean.
Brakes - check for wear and fluid levels.
Exhaust system - check for leaks and crimped pipes and repair or replace as necessary. Carbon monoxide is deadly and usually gives no warning.
Fuel and air filters - replace and keep water out of the system by using additives and maintaining a full tank of gas. A full tank will keep the fuel line from freezing.
Heater and defroster - ensure they work properly.
Lights and flashing hazard lights - check for serviceability.
Oil - check for level and weight. Heavier oils congeal more at low temperatures and do not lubricate as well.
Thermostat - ensure it works properly.
Windshield wiper equipment - repair any problems and maintain proper washer fluid level.
Install good winter tires - Make sure the tires have adequate tread. All-weather radials are usually adequate for most winter conditions. However, some jurisdictions require that to drive on their roads, vehicles must be equipped with chains or snow tires with studs.
