Washington freeze risk for cars

Washington is hard-freeze country: Spokane logs about 132.0 nights at or below 32°F and 33.7 days that never thaw, enough to freeze any water left in the battery, coolant and washer fluid.

Winterizing a car before the Washington freeze

  1. Fill the tank, add stabilizer and drive to circulate it.
  2. Test coolant strength and change the oil.
  3. Inflate tires high or use cradles against flat spots.
  4. Keep a battery maintainer on or pull the battery.
  5. Wash, wax and plug the exhaust and intake against rodents.
  6. Book move-in before October 5.

Washington car winterization questions

When should I winterize a car in Washington?

NOAA's 1991-2020 median first 32°F night is November 23 at Seattle and October 12 at Spokane; winterize by September 28, two weeks ahead of the earlier date. By our car rule Seattle stays driving through November and Spokane through September, then 3 months of dry-day drives follow at Seattle. 12 Washington listings offer indoor or climate-controlled space.

How many months is a car garaged in Washington?

None at Seattle and 5 at Spokane (October to April), plus 3 and 2 months of dry-day drives. Those garaged months hold 44.0 of the 45.4 inches of snow Spokane averages a year (97%), which is the load on a cover or carport roof. At Seattle a car is driving from March to November (9 months), against 5 at Spokane.
