Once you have protected your plants, outdoor faucets, and pets, the parked car is next. Reynolds says every owner should check their tires when temperatures dip below freezing. Deflated tires hurt mileage, and they cut traction, which makes them a real risk on the road.

Fluids come second. Antifreeze keeps the radiator from freezing, so look for cracks or leaks that could turn a bad day into an expensive nightmare. AMSOIL has a step-by-step blog on checking fluid levels at home. Cold can also make car parts brittle, especially ones that already have small cracks or fractures.

Nobody wants to be running late when it's 20 degrees out and the car refuses to start or the tires sag. Batteries and heating round out the advice, and the full list of winter tips lives on The Car Pro website.

A few minutes of checking before the freeze can save you a costly breakdown after it.
