This do-it-yourself winterizing kit from CAMCO includes everything you need to get your car ready for winter weather. The kit includes a bottle of winterizing fluid, a funnel, a hose, and a scraper. Simply pour the fluid into the car's engine, turn on the water, and use the hose to spray the fluid all over the engine. Then use the scraper to remove any excess fluid. Finally, turn off the water and let the car sit for a few minutes to allow the fluid to work its magic.
