Question: 1 / 400

If your vehicle is equipped with an alcohol evaporator, what should you check daily during cold weather?

Oil level

Brake fluid level

Alcohol level

In vehicles equipped with an alcohol evaporator, especially those using air brakes, it is critical to check the alcohol level daily during cold weather. The alcohol evaporator plays an essential role in preventing moisture buildup in the air brake system, which can lead to ice formation in low temperatures. When temperatures drop, any moisture present in the air lines can freeze, impairing the brake system's function and potentially leading to dangerous driving conditions.

Maintaining an adequate level of alcohol ensures that the evaporator can effectively add alcohol into the air system, assisting in the removal of moisture. This prevents freeze-ups that could compromise braking ability. Therefore, daily checks on the alcohol level are crucial for ensuring safe operation in cold weather conditions.
