Truck air systems are under pressure in cold temperatures

TORONTO, Ont. -- Cold temperatures and water can lead to only one outcome, and ice has no place in a truck's air system. Frozen moisture can disable compressors, along with any of the multitude of air valves in the system. Plunging temperatures, like we have seen across much of the Lower 48 in recent weeks will be put air systems to the test. Hopefully your systems are not found wanting.
