Winter driving conditions can be hazardous enough. When the temperatures drop below zero, just getting the vehicle started can be challenging enough. While most people may only experience a few weeks or months in such conditions, having a reliable vehicle to help get us through that time is essential. It can save you from expensive repairs, but more important, it can even save your life. The key is preparation before the sub-zero temperatures occur.
Have a block heater installed or install one yourself. Block heaters provide warmth to the engine fluids, which is crucial for starting in sub-zero temperatures. They warm the coolant and engine oil by being plugged into an AC exterior extension cord. This will ensure the coolant and engine oil in the block stay warm, which will assist the engine start-up and provide quicker cab warming and defrosting.
Test the battery for cold-cranking amp output before winter. Placing a battery charger on a trickle charge setting will also provide warmth to the battery and assist it in starting the car. It will also help make sure the battery stays fully charged. Cold temperatures, especially sub-zero, can decrease the cold-cranking output of a fully charged battery by 1/3 of its potential. Have the battery replaced if the test determines the cold-cranking amp output is compromised.
Check the coolant or have it checked for temperature and pH balance. Straight antifreeze or overdiluted antifreeze can compromise the engine block. Make sure the overflow reservoir and the radiator are both full and the temperature and balance is adequate for winter weather
Check all the other fluids, such as windshield washer, oil and transmission fluid to assure the levels are topped off. A winter grade oil can be substituted during severe winter months if necessary. Use a winter-rated windshield wash and add an additional half pint of rubbing alcohol to the reservoir to prevent the lines and line connectors from icing up.
Lift your windshield wiper blades in the standing position when parked. This will prevent the rubber blades from freezing to the windshield, which can compromise their efficiency.
Charge your cell phone and have a car cell-phone charger to keep it charged if necessary before you leave.
Stock the trunk with blankets or sleeping bags, spare winter clothes and a portable car heater if desired. In an emergency, these items can help keep you warm in the interior of the car. Having a small supply of food, snacks and water will also help survival chances in the event of a catastrophe.
Place a portable air compressor, spare tools, a battery booster pack or jumper cables and simple replacement parts in the trunk as well. An extra drive belt and a set of wiper blades, in the event the ones on the vehicle fail, will help get you where you need to go.
Place a candle or candles, matches or a lighter, a flashlight; preferably crank-powered as batteries will also be compromised in severe cold; a tire pressure gauge and an emergency first aid kit in the glove box or center console.
