Winterize Your Vehicle
Get your hybrid/electric car ready for winter driving the same way you’d winterize a non-hybrid car. Start with checking the condition of things like:
Anti-freeze: With an inexpensive tester, you can test its level of freeze protectant. (Learn more about how to test coolant.)
Oil and filter: Your oil could thicken during winter, so stay on top of regular oil changes.
Tire pressure: Check your tire pressure frequently. Your tires may get low before your indicator light gives a warning.
Engine performance: Have your car serviced before fall ends. Make sure spark plugs and ignition wires are cleaned or replaced. If your area gets really cold, you might want to consider keeping an engine block warmer on hand. Just be sure you’ve purchased a model that’s indicated for your vehicle type.
Insulate Your Grill
In extremely cold temps, some green vehicle owners recommend Cut sections of foam pipe insulation and fit the pieces into the grill to help preserve fuel economy. You may even be able to use old pool noodles instead of buying new pipe insulation. Depending on the make and model of your vehicle, and the degree of cold you experience, you may want to block both the top and bottom grill. Blocking is not recommended for warm weather driving.
