Is your car fitted with a block heater? In case it is either necessary to have a cord long enough to reach or have it facing in.
If it is an older or finicky vehicle you can cut cardboard and slide it under the grill leaving only some of it exposed. Make sure the car isn’t low on gas letting it run for 10 to 20 min is good if its below freezing and sometimes you have poor quality gas watered down or impure and it could freeze next time you fill up consider buying some Heet to top off the tank.
Also seen some people use an old blanket to cover the hood and sometimes the windshield. Gives a little protection from snow blowing in crevices a layer of insulation and can make removing snow as easy as pulling off the blanket. I’ve never done it but to each his own. If you don’t have a proper snow remover an old broom makes quick work of it and it has reach.
Edit block heater is a pas that your battery and a dew other parts are hooked up to you plug it into your house.. Like an electric blanket for your vehicle
