During cold weather, what should be done regarding the alcohol evaporator level?

Maintaining the proper alcohol evaporator level in cold weather is crucial for ensuring the effective operation of air brakes in heavy vehicles. Alcohol evaporators are designed to prevent moisture from accumulating in the air brake system, which can lead to ice formation and brake failure. In colder temperatures, the risk of moisture freezing increases, making it essential to keep the alcohol level adequate.

Checking and filling the alcohol level every day is necessary during the winter months because fluctuations in temperature can cause changes in moisture levels in the air brakes system. Daily checks ensure that any depletion of the alcohol is promptly addressed, thereby maintaining optimal function of the braking system and enhancing safety on the road. Keeping the alcohol level filled ensures that the brakes remain free of moisture-related issues, which are more prevalent during cold weather.

Other options suggest less frequent checks, which may not adequately ensure the safety of the vehicle's braking system during winter conditions. Regular monitoring helps prevent potential brake failures and maintains reliable operation, making daily inspections a best practice in cold weather.
