Battery
Very cold temperatures will reduce a vehicle’s battery power. If your vehicle battery is older than three years, have it tested at a certified automotive repair facility. Also, make sure the posts and connections are free of corrosion.

Exhaust system
Be sure to check the muffler and exhaust pipes for leaks and for their general condition each Fall. Corrosion or perforations in the exhaust system can permit leakage of lethal carbon monoxide fumes into the passenger compartment.

When there’s snow on the roads, ensure your exhaust tailpipe isn’t obstructed by it when starting the engine, and never back into snow banks.

Belts and hoses
The belts and hoses in modern cars lead long lives, but that doesn’t mean they don’t die. Cold temperatures can accelerate the wear to belts and hoses. Part of your winterization should include having the belts and hoses inspected.

Block heater
Consider using a block heater to pre-warm your engine before operation in cold weather. It only needs to be plugged in for three or four hours before start-up, so hook it up to an electrical timer. A block heater helps both your battery and your oil to do their jobs.

Emergency kit
Before the season starts, assemble the things you would need if stuck somewhere on a remote winter road. Include all the usual emergency gear, but also extra items for the longer trips.

Here is a list of supplies you should always have in your car during winter:

1.Flashlight
2.Flares
3.Blankets
4.Shovel
5.Gloves
6.Fuses
7.Booster cables
8.Sand bags
9.Traction pads
10.Scraper and brush
11.Matches and candles
12.Gas line antifreeze
Extra equipment for longer trips: First aid kit, extra clothing, tow rope, chocolate bars (they won’t spoil and they provide food in an emergency, and you’re pregnant wife will be super impressed that you bought her chocolate), tire chains, crowbar.
