If your vehicle has an alcohol evaporator, what should you check and fill during cold weather?

When your vehicle is equipped with an alcohol evaporator, it plays a critical role in preventing the formation of ice in air brake systems, especially during cold weather. The alcohol evaporator uses alcohol to raise the freezing point of water in the air brake system, ensuring that moisture does not freeze and cause braking issues.

In cold temperatures, condensation can accumulate in the air lines, and if this moisture freezes, it can lead to brake failure. Therefore, it is essential to check and ensure that the alcohol level in the evaporator is sufficient. If the alcohol level is low, it needs to be filled to maintain optimal functionality of the air brake system in cold conditions.

This proactive maintenance measure helps to avoid accidents and ensures that the air brakes function properly, even in freezing temperatures.
