If your vehicle has an alcohol evaporator, every day during cold weather, you should:

• A. verify the alcohol content
• B. monitor the alcohol level
• C. inspect the evaporator hoses
• D. check and fill the alcohol level

Answer: (D)

In cold weather, some air brake systems use an alcohol evaporator to prevent moisture in the compressed air from freezing. The alcohol is consumed as the system operates, so the level can drop. Because of this, you should check and fill the alcohol level every day to ensure there’s enough alcohol to prevent freezing and to keep the air dryer functioning properly. Verifying content or inspecting hoses aren’t the daily actions that guarantee the system stays protected; only daily replenishment ensures the alcohol supply remains adequate.
