The winter-summer door provides a means to mix warm air from the engine cab with cold outside air to prevent ice crystals from clogging the baggy air filters as well as to maintain warmer engine manifold air temperatures during cold ambient temperatures.

2
00:00:16,167 --> 00:00:21,875
The winter-summer door is located in the floor area of the combustion air filter compartment.

3
00:00:21,875 --> 00:00:29,792
In warm weather conditions, the door is in the down position and closed to block the air passage that leads to the engine cab area.

4
00:00:29,792 --> 00:00:34,250
This allows full flow of air through the plastic air cleaner panels.

5
00:00:34,250 --> 00:00:46,667
In cold weather conditions, the door is in the raised position to partially block the incoming air from the plastic air cleaner panels while opening the path for the warm air to travel from the engine cab area.

6
00:00:46,667 --> 00:00:50,708
The winter-summer door requires no routine running maintenance.

7
00:00:50,708 --> 00:00:56,917
However, if the door is not in the correct position for the climate, locomotive performance may suffer.
