cold start

cold start
Getting a vehicle started which has been sitting for some time and cooled down to ambient temperature. When temperatures reach -40°, a vehicle may require three or four times as much battery power as it would during the summer. As well, the carburetor or fuel injection system needs to be much richer (more gasoline than air). Because condensation has a tendency to build up in the gas tank during the winter, the liquid going to the carburetor or fuel injectors may be diluted with water -- thus making starting more difficult. The application of isopropyl alcohol (marketed as "gasline antifreeze") removes the water from the tank.
